Starter Sticking

[ilovemyblazer]

My starter keeps sticking and its pissing me off. Just put the new gear reduction starter in yesterday, had put in a new relay (CUCV Electric) before that. The starter work a few times without sticking, but then just started to. Now I cant reconnect the batteries because the starter engages instantly.

Have you replaced/upgraded your under-dash starter relay? (aka, doghead relay mod)

Yes agreed to do this, first mod I do one any CUCV I buy.

The under dash relay has been replaced? Could also be the starter itself as it too has a relay solenoid but they usually fail open, not closed like the under dash unit.

Pull the under dash relay and see if the starter still engages with reconnection of the battery. A battery disconnect switch would be beneficial in this test to avoid vaporizing battery terminals.

 

[doghead]

A battery disconnect switch, used incorrectly in this case, will cause more damge that it will prohibit.

Replaced the under dash relay with the one I ordered from CUCV Electric. To my understanding that is the same thing at the doghead relay mod? I do not have a battery quick disconnect, but since this is happening I was thinking of it. The starter is not even 24 hours old, and it works as it should other than the sticking.

Just checked their website.

The relay that CUCV electric sells is the stock unit, NOT the modified one.

Your new relay has failed in the closed Position.

This is what you need.

Did you accidentally allow the wires on the starter to touch? Small one to the big one?

Post a pic of the relay you installed. I don't know what CUCV E has or what you received.

The under dash starter relay from CUCV Electric is not the same as the Doghead mod. The CUCV Electric relay is a heavier duty replacement for the stock relay. The Doghead mod is a much *heavier* duty relay.

Couldn't a battery disconnect switch be placed on the cable that runs from the positive side of the 24v buss to the starter? I don't see how this could cause any problems like those seen when placing the disconnect switch directly on the battery cables. This would allow for isolation of the starter.

As mentioned before, try disconnecting the under dash starter relay and then reconnect the batteries. If the starter still engages at that point, than the solenoid mounted on the starter is bad. Are you certain that the solenoid is rated for 24v? That is a common mix up with replacement starters.

You'd need to do more. Once the Bendix has the starter(mounted) relay closed, you have a circuit there(small purple wire) that could continue the action/load. That would be devastating.

Also need to disconnect the negative on the front and rear battery during a run-on, to eliminate any damage.

 

[doghead]

Just do the Doghead relay mod, and you'll be fine(no worry about starter run-on).

 

[ilovemyblazer]

Here is a pic or the relay, it looks just like the old one only shinier. The starter is from DB Electrical and is 24v and made for the cucv's, even said so on their page. I did ALL of the electrical work with the batteries disconnected and did not cross any wires.

I do not understand how a relay can go bad after like 10 starts. If my ****ty luck continues with this truck you guys might see a cheap M1008 in the classifieds..

 

[doghead]

Read the forums. I didn't dream up the DH relay mod, just to keep people busy...

It resolves a fatal flaw with the stock system.

Why do you see so many "new" cars in the dealer service department? Things break.

So with you being 18, take it from some old timers, an older vehicle will require constant work. Some more than others.

If you go back to your thead on 7-24-12, "New starter confusion" In my post #9 and the last in the thread, I had advised you to perform the doghead mod before you install a new starter. That being said, You purchased the same original equpment crap relay from CUCV electrical. The doghead relay is a 200amp relay, It snaps when the starter is ingaged, it does not sizzle like a 4th of July sparkler like the original. Your choice, sizzle and burn, or start. I did this mod a few days after I got my truck.

 

[ilovemyblazer]

Ok, I did the doghead mod and it works great. Thanks for the advice. Next thing is when I turn the key the starter spins but does not engage with the flywheel, I can here it and it sounds like it spins nice and freely but it just doesnt go out to meet with the flywheel. Did I just burn through my new starter?

 

[wayne pick]

Well I hope not. Go back and check to see if you wired the doghead mod solinoid properly.

 

[wayne pick]

You must have wired the solinoid right as the starter is spinning. Tap, I mean tap on the starter lightly with a medium sized ball peen hammer while trying to start it. In park, E brake mashed to the floor. You may have gotten the starter solinoid hot, now IT sticks. See how you have to listen to advice? I didn't at your age but learned quickly and expensively. Be careful when working under the truck.
