[Chevelle-list] Electrical Short?
My 65 has an old after market wire loom. I have just noticed that the brake light circuit has a short. I have blown two 20 amp fuses for that circuit. The running and turn indicator circuits appear to be normal. I have bought a new brake light switch, but have not installed it yet. I can't see how this switch can caused the fuses to blow unless it is just a bad connection. I will check the light plugs for a ground short today. Hoping not to have to trace the wire from the fuse box. Anything I missed? Larry Everyday Is A Saturday

Larry, the switch itself should not cause the fuse to go. I rewired my 67 and as I recall, the brake light circuit is normally open and pressing the brake applies power to the circuit. So, start at the switch with a ohm meter and check it. Then with one lead of the ohm meter connected to chassis ground, check the circuit. Then the results of that reading will tell you you have eliminated or not certain parts of the circuit. you can jiggle wires and pull bulbs out and see what changes. hope this helps. mike From: Larry Williams larrydwilliams1...@att.net To: chevelle-list@chevelles.net Sent: Thu, June 2, 2011 12:33:31 PM Subject: [Chevelle-list] Electrical Short?

Re: [Chevelle-list] Electrical Short?
If you still have the original brake light sockets, I would also check them as they ground on the body and if any water has gotten into the socket itself, then the middle of the bulb connection may be the problem. Put some die electric grease if they are ok and you plan on continuing to use them. You can also but aftermarket replacements (If you are not all orig) and they utilize a ground wire that you can ground elsewhere.

Re: [Chevelle-list] Electrical Short?
The bulb socket on my '72 was shorted out (inside the plastic...) And would back feed both sides! I had replaced bulbs, brake light switch... Until I replaced the socket! We took the old socket, cut the plastic away and THERE it was... As I drive the car so infrequently, I'd just replace the bulbs Until I had a day to simply putter with it! Speaking of that... maybe a quiet night with my Chevelle is a GR8 idea!

Re: [Chevelle-list] Electrical Short?
Yea, I'm not sure when, but they went to the plastic sockets with the sep ground wire. On the earlier models (Like my 66) the sockets had only 1 wire for the positive and the socket grounded itself on the body. Makes for fun short tracing.
