Car won't stop cranking
#1
So the car won't stop cranking, i pulled the battery cable and it still didnt stop for a good bit. Ive replaced the starter, solenoid, and battery cables and it hasnt happened recently. But it randomly happened again tonight so i pulled the ignition switch thinking that it was sticking. I tried hooking the battery back up but its still live and trying to crank even with the switch out. I just purchased the car and it seems someones done a hack job already. Ive looked over the forums and i haven't seen the same problem yet. Sorry if this is a repost guys. Any help will be greatly appreciated.

Your getting power across the solenoid either because it's stuck or wired wrong...post a pic of the wiring on it so we can see. If you disconnect the starter wire from the solenoid you can locate the problem without damage to the starter

Alright, ill get a picture and post it in the morning. I looked at one of the threads on here and by that Ive got it wired up right to my knowledge. So ill see what you guys think tomorrow. Thank you

That is really weird you pulled the battery cable and it kept cranking,

I'm thinking the harness from the alternator to the voltage regulator and starter solenoid is wrongly wired. Possible missing junction block isolator causing ground loop.

Post pics high res of that area.

I would've thought pulling the main fat + battery cable would stop everything.
I'm surprised it didn't melt the thinner alt cable if that was how it was cranking....!

This is going to be a little sketchy as it's from a weak memory of when I changed out my starter. The stock was a single wire (I think) and the new had 2. I seem to recall the instructions saying that you should not use a small jumper across the solenoid to get away with running only one wire to the starter. It said something along the lines of doing so will create a situation where the solenoid would actually store up a charge and eventually fail. Wondering if this is why yours still cranked with battery disconnected.

It's a long shot but thought it might help.

I think you have a small PM starter with an integrated solenoid fasteddie.

What MAY be going on in the OP is a bad bendix. It may engage and not want to disengage. If it were mis wired it likely would not be intermittent. When my switch went bad the starter would not disengage every time.

Like i said, I just bought the car and it seems that a backyard mechanic has gotten a hold of it once or twice.

Red cable closest to the battery was 12v, the connection beside of it which was the "I" was 12v, and the wire to the starter was 12 volts. Remember I have the ignition tumbler out because i thought it was sticking. This is the second solenoid I've had on this car.

It is mounted upside down..It should look like this below...The main wire to your starter is going to your battery and vice versa..Looks like you need to install it right side up...I would get a new one thou and install it properly..They are cheap and after it having the power going the wrong way like that, i would not trust it anymore.

A chevy guy must of installed it! hehe jk

Is that the voltage regulator underneath teh starter selenoid? Whatever it is is upside down also.... not sure if that matters. And there are 2 disconnected wires... shouldn't they be connected?
