Thread: What is this???.......

Tweet

What is this. It is inline on the red wire from the positive battery cable.

This is my buddy's ride, hes in vegas and is having charging problems, replaced battery, didnt help, replaced alternator, didnt help.

This "thing" was covered up and he didnt notice it at first, he thinks it could be bad, and wants to get rid of it and try.....but i told him dont try yet, it could be a resistor.

The entire set up use to charge and work fine, now hes getting electrical gremlins.

Its 59 chevy pickem up, new wire harness, A/C, 350 chevy motor, 350trans, it has a satallite radio reciever no amps or anything crazy, i dont think it has HEI which makes me think it could be a resistor........but i just dont know what it is

It could be a very high amp fuse and/or circuit breaker.

Yep, circuit breaker. Probably about 40 amp.

Thanks you guys, this will defenitly help cuz he bought the truck already built and lost the contact info to the guy that built it , I appreciate the quick responses....thanks


Heres a pic of the culprit

That's a nice looking truck.
After looking at the picture of the circuit breaker you posted I noticed that the hook up from the battery clamp to the breaker looks a little toasty. That to me indicates a bad circuit and before you do anything else you should find the cause and eliminate it. That is way to pretty of a truck to see it burn to the ground.

Having been there, done that, I can almost guarantee that you don't have good grounds, especially after seeing all the fresh new paint. Using 2 new ground straps, grind the paint off down to bare, shiny metal on the firewall somewhere and grind a spot on the frame. Make sure these ground-off places are large enough so that the ground strap isn't laying on any paint. Either sheet-metal screw the cables down or drill through and use a bolt and nut. Same deal with the motor. Find a place on the block where you can attach the other cable and run it to the connection on the frame where the firewall cable terminates. After you've done this, coat both the outer and inner sides of the hole/screw/bolt/nut whatever on each cable end with RTV to completely seal both sides of each connection from atmosphere and water being splashed up from the road.

thanks for replying, I should have mentioned that the black stuff on the wire, is some type of sealant, it was covered in a round tube and sealed on one end.

It is a nice trcuk and hes been really happy with it, the gremlins are recent. ya his plan is to keep it off the road until it is fixed properly. hes trying to get the repairs completed by begingin of may, i guess theres a rod run in northern nevada hes heading to, it will be my first time there.

You know your right about the paint, it is really thick......and nice, i noticed that while poking around under there. This is all great info, thanks for the reply.



when its figured out and repaired i'll post an update
