sorry Chris, i got that.
Edgeman was asking about the starter solenoid, he read about in your post.
I was trying to tell him where THAT was.
RJ i will take a picture of the shut off relay and shutoff solenoid and post on here for you.
a few things to look at when you have a no start or no pull up condition.
1. shut off solenoid relay- located on the firewall just to the left of the center of truck, above fuel filter canister. there are two relays up there. its the one towards the drivers side.
2. starter solenoid relay - located in the Power Distribution Center, black box, on left (drivers) fender between battery and hood hinge. you can swap it with the trailer relay for testing.
3. connector at shut off solenoid- clean inspect, then jumper the white wire to 12v and verify the solenoid actually pulls up. if not go buy a new one.
4. clean and inspect blue wire on battery teminal of the left side (drivers) battery. also check that the fusable link is good.
a few things to check if starter continues to run or truck wont shut off.
1. starter motor contacts. remove starter and clean or replace severly burned contacts inside.
2. starter solenoid relay- located inside the PDC labeled as such. you can swap it with the trailer relay to test.
3. check both batteries with a stress test. if questionable replace
4. clean and inspect all battery cables (both sides, both teminals)
