I have a 93 F250 with the 460. On a semi regular basis I have problems starting the truck. I'll hear a click, No cranking. I've read about the cables, but I think the problem may be the relay located on the passenger side of the engine compartment. Is this the starter relay? If not what the heck is it.

TIA

I had a very simular problem when I was young and it cost me $200 to fix, $100 tow job, $50 tech, and $50 for a new battery. The problem came back a few days later. I found that it wasn't getting a good ground. Yup, thats it. $2 worth of sandpaper & a wire brush fixed my problems and I'm sure helped avoid many more over the years.

Maybe its time to go for the grounds. Disconnect the battery first off. Replace the battery cables if theres any signs of corrosion on them. Clean the neg cable ends to the block, frame, and body. The body is just in front of the battery and once you get the bolt off you'll see it grounds thru a painted area; sand down to bare metal is what I did/do. The engine and frame can be found by following the neg cables down.

Next take the solenoid off and clean the back of it as well as where it mounts to the body. It grounds thru to the body. Once again the fender is painted...

Next disconnect the starter and clean its cable and both surfaces where the block meets/bolts to the starter. The starter gets ground thru the block.

Hook everything back up and try her.
