Ive got some major problems with the starter / starter solenoid getting to hot.
Usually have to sit in the truck and wait for 30mins for it to cool down after a drive. The starter is a 24V Delco starter and im trying to figure out how to remove some of the hot-contributing stuff..

On my current setup the starter always have 24V present on the battery connector... I wonder if this is contributing to the heat? Should i maybe only give the starter power when im starting the truck?

All help is massivley appreceated..

 

Have you checked to make sure that the starter is disengaging properly?

 

no sir.. how would I test that?

I absolutley dont think that its not disengaging.....

Its just sometimes when hot it wont do anything. Leaving the truck for 15-30 mins then trying again always works..

 

today the car started fine 5-6 times while driving around to diffrent stores, then later after beeing still for 40mins when i was going home from the garage the truck started fine, i turned it off, then i tried to start it again, and it was dead.

Its getting frustrating... maybe its time for a new starter ?

 

I think if it's not disengaging you should be able to hear it trying to crank.
I think this is probably caused by a short in your ignition tumbler or ignition switch

 

bypassing all the ignition just putting power to Start and Bat on the starter also fails, that should rule out the ignition system...

solenoid just wont close the bridge when its too hot.

 

Try a starter heat shield blanket.
