'82 C 105 - Lights just stopped working

Recommended Posts

Lights on my C 105 simply stopped working. One day they worked...next they didn't. Everything else works fine. Fuse is ok. All connections appear to be good. 

 

Not an electrical type guy so any help appreciated. (My bright (pardon the pun) idea of "fixing" it is simple - go straight to the battery...but I have other things on my to do list...:D)

 

Thoughts?

may be a faulty switch. Get a test light out and check for power to the switch.

Since both lights went out at the same time I wouldn't suspect the bulbs. If it's not the fuse, I would have to guess it's a bad ground. Since the lights are grounded through the hood, my guess is that the hood ground is bad. I'm not sure where the hood ground point is, but on earlier models it was through the pivot assembly.

I started running a wire from one of the hood hinge bolts to an engine mounting bolt to assure a better ground.  Put  a disconnect in it so you can remove the hood if you need to.

Thanks for all the input...

 

Even baseball pointers...:deadhorse: (although this emoji appears to only address the potential problem with the "tail" lights...)

Related  question to this topic. If my lights keep blowing the 3 amp fuse. What should I check? I have a 75 C-120

Found where the 101639 fuse is listed as SAE 20 but likely should be SFE-20 amp fuse for the lighting circuit.

 

Not knowing the gauge of the wire maybe try a 10 amp fuse.

For some reason I thought the 3 amp fuse was what WH used to run the headlights and taillight.

Yes fans! No ground issue. The PO threaded the wire THROUGH the hinge for the hood. Over time the rubbing motion at the hinge wore through the wire. Wasn't noticeable from the visible side. Cut, spliced and nutted together and all is good!

 

Thanks again for the input!!!
