SA Idler Troubleshooting Overview: The solenoid pulls the carburetor throttle plate closed and the engine drops to idle speed RPM or less. When the idle board senses demand to idle up, it opens up the ground side of the solenoid circuit, the solenoid releases, and the governor pulls the throttle plate open and maintains weld speed RPM no load and under load. The control PC board senses demand from the reed switch on the range switch weld demand or from the reed switch on the PC board auxiliary power demand. The reed switch closes by magnetic flux. There is a transistor on the PC board acts like an electrical valve, open it up, and current flows; the solenoid pulls in.
Australia Your first test and probably the most likely cause is to determine if something is keeping power on the small wire on your solenoid. Its a little difficult as you need to be at the ignition key and the starter at the same time. Since you have already stated it operated 10 to 20 times before the problem occurred its even more of a challenge as its a intermittent fault. My suggestion would be to attach a temporary wire to that small wire and run it over into the cab of the machine.
In the cab you can wire to a small bulb and the other side to ground. With starter number four installed you can watch that light for a few weeks and you should only see the light illuminate when you are cranking the engine.
Most vehicles use a starter-mounted solenoid that functions as a high power switch to connect the starter drive pinion gear with the flywheel to start the engine. Most on-starter solenoids are easy to wire as you mount the starter on the engine. Other solenoids–mostly on Fords–are remote mounted.
That should be simple This one is on E-Bay item number: That is probably not enough as these winches will draw from 50 at low power to AMPS under maximum rated pull I like to use two Solenoids I like to take the Hot trigger wire to a dash mounted separate stand alone key switch at my winch controls I then take the second Solenoid and in a convenient place up front say near the grill but inside the engine compartment I mount the second Solenoid in line with the same Battery cable that is switched up stream from the key.
From there you have many choices to connect the two small wires that will now activate the winch line once the power is turned on via the Key Switch I personally don’t use a remote. What I do is take one wire back to the dash and mount a HD push button switch. Coming off the same terminal at the second Solenoid I put a second push button switch mounted inside the grill that you can easily reach from the front of the vehicle This dual Solenoid method also protects you in case one should ever fail or burn up
I re-located my starter solenoid inside the fenderwell on my 89 and I have wires crossed or not grounded somewhere. My battery is in my trunk so let’s get that established not like it matters. What all should be grounded to the “-” side of the solenoid? Right now I just have the thick cable from the engine block. I have another wire grounding the engine to the frame. It has been this way for 6 months with no problems.
Dec 26, · Re: is it possible to hook up solenoid wrong? On the big terminals it dosn’t matter, it’s just a big switch. Some times, the manufactuer will connect things to the “battery” side though.
How to Replace a Car’s Starter Motor Replacing a starter motor is usually a straightforward but inconvenience job. Here’s how it’s done. Jul 12, Advertisement – Continue Reading Below This gear-reduction starter left is a lightweight drop-in replacement for the older starter that failed. By spinning the armature faster and reducing its output speed with a planetary gearbox, it’s possible to get the same starter power in a smaller, lighter package.
That’s the noise your car makes when you twist the key. A few more clicks and now you’ve got a metallic screeching that makes all the dogs in the neighborhood start to bark. The dash lights are plenty bright, the headlights don’t dim much when the key is twisted, but obviously something is wrong. With the clock ticking, you resort to that old standby: A few more screeches grating enough to make you cringe, and the engine finally spins merrily.
After work, it’s the same story: Clunking and clicking, a few bars of the “Ballad of the Tortured Ring Gear,” and you get to drive home instead of ride in the cab of the tow truck.
About the only drivetrain part remaining was the original factory 3. Sparing no effort, Miracle had the frame and control arms powdercoated. I wanted a no-hassle street driver but with plenty of get up and go, so I went for a ci Rat motor from Ateco Engine in Illinois.
Jul 17, · My question I have is that when I hook up the 6 volt battery (positive ground) the starter just spins over but the car won’t start. I reversed the pos/ground cables and the car would start, although the starter turns over very slow.
When jumpstarting a car you essentially give the dead battery just enough boost to start the engine and then rely on the alternator to charge the battery the rest of the way. When using a battery charger, you allow the battery to charge all the way before it will be used again. This should answer important questions such as what the voltage requirements are for charging your battery and whether or not you should remove it from the vehicle before charging. There will be a manual with your battery charger that provides details for the appropriate use of the charger.
Working in a well-ventilated area will help dissipate the hydrogen gas that batteries generate from the sulfuric acid within their cells. Also, make sure to keep any other volatile substances, such as gasoline, flammable materials, or ignition sources flames, cigarettes, matches, lighters away from the battery at all times. Glasses, gloves, and other protective gear is a good precaution.
Hydrogen released within the battery quickly converts to a gas and expands, this can cause the battery to explode if venting mechanisms fail. These accessories draw power from the battery and should be turned off before removing or charging the battery. Most batteries will be found either under the hood of the vehicle or in the trunk. It is also possible that your battery may be under the rear seat, and sometimes the battery can only be accessed from underneath the side of the car.
There are a few ways to tell which is which: Compare the diameters of the battery posts.
When you turn the ignition key to start, the solenoid pushes out the starter gear to engage the starter ring on the driveplate and gives the motor 12V which turns the engine. If you hear a metal-metal grinding noise even after you release the key, the starter gear is stuck and grinding against the flywheel starter ring. This can be caused by excessive dirt build-up on the starter shaft or a bad bearing inside the starter. Always disconnect both positive and negative battery terminals and make sure that there are no flammable fumes or sources of ignition nearby!
Follow all precautions listed in the factory service manual. Take care to not touch the battery terminals together or let any metal object like a wrench, wristwatch, or necklace touch them together!
To wire a volt starter solenoid, first disconnect the black negative cable from the vehicle’s battery, and then connect the red battery cable to the large bolt on the solenoid. If it is a remote-mounted solenoid, you must connect a control wire between the control circuit terminal on the solenoid and the car’s ignition bypass terminal.
Try this If you have a volt meter or 12 volt tester, try this. Remove the two wires that go to S and I and don’t let them touch anything. Then go to your key switch, and turn it to on. Check for voltage at both wires to battery ground. If you have voltage at one of them, then that one has power when the key is on, or the motor is running. Turn the key to start, and read the voltage on both wires again may take 2 people to do this.
The other wire should have voltage now. That is the one that controls the starter solenoid.
How does a mechanic diagnose the P code? This enables your mechanic to determine the proper gear ratio for your vehicle. The mechanic will also: Common mistakes when diagnosing the P code Shift solenoid malfunctions are often diagnosed, and the solenoid replaced, when the problem is actually something simpler, like low or dirty transmission fluid.
How serious is the P code? Anything that causes your vehicle to shift improperly can make it difficult to drive safely.
When necessary, instructions for the 5. Raise the trunk cover using the clasp. Grab the clasp and lift the cover up. The clasp will hook onto the trunk seal. Note If your trunk seal is in poor condition, then the seal may become detached from the trunk. Rest the trunk covers clasp on the trunk seal. Remove the carpet panel.
The following information applies to the typical Nippon-Denso ND starter motors. Have you noticed your starter turning slower and slower, or worse yet, you turn the key and all you get it a loud click and a slight or no dimming of the lights? My 22R-E equipped 4Runner, had over , miles on it, and I’ll bet the starter is bone stock. The starter is actually composed of two main parts, the series-wound starter motor itself and a solenoid which serves dual functions of pushing the drive gear into the flywheel as well as making a high-current contact to supply battery power directly to the motor.
Starters can pull many hundreds of amps of current under load and the solenoid acts like a giant relay taking the low current signal from the ignition switch to control the high current for the motor. The solenoid consists of a steel plunger that is pulled into an electro-magnetic coil, that is energized by the ignition switch.
The starter solenoid hooks up as follows. There are 2 large post, the battery cable attatches to the one near the battery. The cable that goes to the starter attatches to the other post.

Squeezing hose clamps and general holding-on-to-things. Large and small flat-blade screwdrivers. Used to remove the hose clamps on the air intake. A bag of rags. You will need this.
A Ford starter solenoid is one of the key components to the starting system of most older Ford vehicles. It’s essentially a big relay, which provides power from the battery to the starter motor when the ignition key is turned over, starting the vehicle.
Are there any changes that I need to make in my wiring and connections? The points distributor used a resistance to lower the voltage to the points in the run position to prevent wear on the points. This was done with either an external ballast resistor or a resistance wire in the ignition circuit depending on the year of the car.
When converting to an HEI there are three issues which must be addressed. The first concerns the resistance in the run circuit. The second concerns the gauge of wire feeding the HEI distributor. The third concerns the starter 12 volt override and the ignition switch. When using HEI, the distributor requires a 12 volt feed. In order to achieve this the ballast resistor or the resistance wire must be removed from the circuit and replaced with a pure 12 gauge feed wire. This feed wire must be 12 gauge from the ignition switch to the bulkhead and then from the bulkhead to the HEI power terminal.
This solves the first two concerns.
Big fat gnarly wire is the main power wire, as you surmised. It comes directly from the battery. It provides power to the solenoid, not to the starter though well, ultimately it gets to the starter There are two parts to the starter in most vehicles. The larger part which actually attaches to the engine is the starter motor.
This, as the name implies, is the part which actually gets the engine to spin.
Heat soak is a condition where the heat from the engine and exhaust system heats up the starter, solenoid, and wiring which causes an increase in resistance. [ edit ] Remote solenoid The following changes will help this situation by removing the relay function of the starter solenoid to a cooler part of the engine compartment.
Back to Top Post by jeep on May 5, 1: I have the same 49cc motor with electric start built in and there’s no original ignition, wiring harness, lights, – just a pull start, and I wanted to hook up a key switch so I didn’t have to pull start it all the time. I finally got mine working so I just wanted to put this out there for anybody else who wants to do the same thing.
You need a 12v 7amp sla battery, 12 gauge wire, A 2 wire key switch for 49cc atvs, motorcycles, etc, and a universal starter solenoid. It was nowhere near as expensive as some people were saying it would be and it was pretty simple to set up. Anyway hope this helps somebody looking to set up the electric start on their 49cc instead of having to use the pull start.
