The best part was 'did you know that some solenoids have to be grounded to work? But, it is finally mounted after almost 3 weeks. One, in the center, will be the big red cable from the battery. The 1G starter looks like this and only has two connections. Please hang with me during the read, I am far from an electrician and it is not one of my favorite or knowledgeable areas with vehicles. The wire that goes from solenoid to starter motor is hook up and the small wire to the small bolt is hooked up. Scrape to bright metal as best you can.
A related topic there is two windings in the solenoid the Pull in and the Hold in windings. Remove the starter retaining bolts then the starter. You must bring number 1 cylinder up to top dead center on the compression stroke … then lift the distributor cap and see which tower the rotor is pointing to. I am going to try and explain some key items with the starters of our earlier model trucks. You should only need to wires to starter.
Our starters on earlier trucks came in 2 versions, Which one should we be using? This wire makes its way to the alternator and is the location of the charging system fuseable link. Look for a Heavy Battery Cable typically Red and a Red Wire to energize the Solenoid. Mine just happen to be the cold weather that hit the hardest, in addition to aged engine and some older wiring. All other trademarks and names are the property of their respective owners. I think the large on goes to the top starter bolt ground and the smaller one goes to the alternator, however, I'd try and track them back to the battery ground prior to connecting the battery. Also is the small wire a ground that should go over one of the starter bolts? That should pretty much do it. Symptom was that the starter would turn over very slowly when the engine was hot.
In addition to this wire, many vehicles have a wire or pair of wires going to the solenoid housing on the starter. The last wire which is purple in color mounts to the small stud on the solenoid, and is held on by a 9mm or 10mm nut. I thought when I disconnected them, they each had a location but I cannot figure out which goes where. I have diagrams if you need them. The last wire which is purple in color mounts to t … he small stud on the solenoid, and is held on by a 9mm or 10mm nut. Connection 4 is the I connection on the starter solenoid and it feeds current back into the ignition, and it is not used on a lot of vehicles after 1981, but if your vehicle has it it will be a small push on connector that will not have any power from it at all, and it will usually be a black wire with a white stripe, but that is not always so.
Disconnect all these wires, remembering which terminal they went to. Believe me, I have read many forum arguments that were debating amongst themselves on this subject and everyone felt they were right. The coil should have a small black … wire coming from the distributor attached to the post marked neg on the coil. There do not appear to be any wires coming from the startermotor itself, here's what goes to the solenoid:. There are two large terminals on the starter and two large wires going directly to + and - on the battery.
It is a large cable from another big lug on the solenoid to the motor. This kind of amperage stresses all of the components in the starter circuit, including the battery, battery terminals, the battery disconnect switch, the cables including the ground path, and any remote solenoids. Going through the resistor wire the spark would be too weak to fire the plugs well enough to start under some conditions, like cold winter weather. This is overloading the starter cable as it is not designed for that sort of load and is cooking itself. This energizes the starter motor windings and turns the starter. He tested the starter and it tripped the breaker on the tester two 2 times.
The ground is provided by the bolts into the bellhousing. The hold in winding goes between S and ground and always draws current. If the engine has no ignition during cranking, then the wiring of the coil is going to require an R terminal signal. Problems with these components are hard to find because they appear fine at rest or under a light load, but generate high resistance under heavy amperage draws. One from the battery and one from the harness. Hi guys, I just finished up installing a wiring for my '03 Chevy K1500 and I have a question a out the solenoid. If it is rather stout then that would be your battery cables.
Occasionally you will see a smaller gauge black wire leading down to the starter as well. Starter Cable Testing First of all if the car is a manual tranny put it in neutral and set the parking brake firmly. I could replace the positive battery cable, but come on, my language above zeroed in on the former negative battery cable being the problem. Place the old starter side by side with the new one on a table and compare them for similarities and differences. Depending on the application, there could be a few different types of connections transferring power from the electrical system of the vehicle to the starter. Information is subject to change and offered as is without any warranties or guarantees.
Yet another way, but more expensive also. See it in Louisville next week the Street Rod Nats! Track the wire attached to the negative battery terminal to wherever it goes. I have never messed with any chevy starters before only chrysler ones. If it's anything like earier 80's there will be 2. The problem was a weak spark and I chased the problem with money for a long time. Tighten motor retainers to 20-25 ft.
We're talking a good 3 hours of pulling my hair out. There is one small wire which actually activates the starter, that one is plugged in the right spot. A big cylinder shaped object, with a smaller cylinder shaped object attached to it, with wire running into it. These solenoids are located in the engine compartment close to the battery, which makes it much easier to wire. When connecting an on-starter solenoid, be sure to rest the solenoid somewhere convenient while wiring it, since it is heavy and awkwardly shaped, making delicate connections difficult to wire if holding the device in one hand.
