wierd Rear brake light problem

[ericindc]

So having some electrical problems.

The rear lights work, but when I depress the brake petal the passenger rear lights go out completely. The drivers side lights and brake lights work normally.

any ideas? Thanks.

Sounds like a ground issue. There seems to be a lot of these lately. Attach a jumper wire to the back of the passenger side brake light where the wire goes in. Attach the other end of the wire to a ground, then check the operation of the brake lights.

tracked down the grounding issue. Just had to replace a couple lines and sand down the taillight housing a little bit.  Sill having issues with low electric power at idle. The batteries dim unless rpm is up.

are you saying headlights dim unless RPM? that is fairly common on these cars. There are several post on relays etc. that help with that

  Check Goodies post on fitting relays, it is a must, will also take the load off of your 30+ yo headlight switch.

Well, thats good to know I was worried it was something else.  I just installed relays on my CJ7 to handle the H4 Xenon lights so it should be a similar setup.  The hard thing to find is automotive circuit breakers that will reset.

Assuming you mean breakers that retrofit into a glass fuse fusebox, don't the Dorman units self-reset?  P/N 84686 (15A)?  Or are you referring to standalone units?  Its been a while but I'm pretty sure the Dorman's we used to sell at the parts store were automatic reset units.

If the former, then Rock Auto has them, and the "Help!" line the Dorman units are part of may be available at quite a few retail locations.  They also list blade type breakers for later fuse boxes.

Well no, I meant stand alone breakers.  Once you build a relay, you have a direct battery connection so you need an inline fuse or breaker to deal with it. I will try those locations for the breakers since It sucks to blow a fuse and have your lights go out. Especially on my CJ7.   Makes nightime water crossings more nerveracking.
