Customer Question

I have a 4.3 cobra... I just hear a click when trying to start... It turned over previously but had dead battery. Now I charged the battery and it just clicks? Battery has plenty of voltage. I jumped the sylanoid and still just a click. Any advice

Hi, Kerry again

Either power isn't getting past the solenoid or the motor itself is bad.

It's usually just the solenoid, you can find out buy by-passing the solenoid.

If you jump across the two large terminals on the solenoid, the motor will kick in if it's good.

You need to be careful doing this, there will be a heavy spark.

Another way is to jump from the positive terminal on the battery to the bottom large terminal on the solenoid

with a battery cable.

Just do it for a second, if the motor is good it will spin right away.

What do you mean by the motor is bad? Could it be a starter itself?
Expert:  K. Kergan replied 10 months ago.

Sorry for the delay,

Either the solenoid or the starter motor is no good,

the easiest way to rule out the solenoid is to bypass it as I explained.

When I say the starter motor is no good, I mean that when you put power directly to the motor, it doesn't do anything or, in some cases makes a groaning noise and doesn't turn.

If the solenoid is no good, when you engage it just clicks.

If the motor is no good, the solenoid will also just click when you engage it, but if the motor is good, it will spin if you bypass the solenoid.

Do you know what I mean by by-passing the solenoid?

Expert:  K. Kergan replied 10 months ago.

Yes it could be the starter itself, but it could be just the solenoid that needs replacing.

Expert:  K. Kergan replied 10 months ago.

Sorry, I assumed some mechanical knowledge on your part.

Here's the thing, there are two solenoids.

One is on the engine harness and one is right on the top of the starter.

There is a solenoid mounted on the engine which engages the solenoid mounted on

the starter.

Either one could be the problem, or the starter motor itself, we need to figure out which it is.

The easiest way to determine if it's a solenoid or the motor is to jump power directly to the motor, if the motor is good, it will spin.

If it doesn't spin, the motor is no good, if it spins, one of the solenoids is no good.

If you aren't understanding this, shoot me some more questions.

If the motor spins, we need to figure out which of the solenoids is bad.

Look up "slave solenoid" and do a little reading and get back to me, please.

Expert:  K. Kergan replied 10 months ago.

There will be a yellow wire with a red stripe going from the slave solenoid large terminal to the starter

solenoid small terminal marked as the 'S' terminal.

Do you have test light or voltmeter?

You have not accepted any of my answers, there won't be more.
