Edit: Renamed the thread because what started out as one electrical problem has led to others and I'm hoping to capture all the information in this one thread.
Initial Problem: When I turn on the 72, the red light on the dash (in the top part of the gauge on the left side of the dash) blinks and won't stop. I've made sure the e-brake is all the way off. I'm wondering where is the switch that controls this light? I've read that when the brake master cylinder is replaced, there is a switch on the MC that needs to be reset. I used a MC from Rock Auto and there is not reset switch button. Only the electrical switch that activates the brake lights. I have a brown wire that is connected to nothing in the area of the e-brake handle. I've tried grounding it but the light still blinks on the dash. Any advice would be appreciated.

ok, issues 3 (and 4) resolved.
After resolving Issue 2 - the flashing brake light, I did 2 things. I replaced the headlight relay and then put everything back together and reinstalled the upholstery. I had replaced the original 4 post headlight relay with a 5 post relay. Headlight relay post I had found some info on the Samba website that said that I should just run a hot wire to post 30, and therefore not have to run a jumper between 30 and 56. This was not the case. A JUMPER was REQUIRED. I removed the constant power to 30, put the jumper in place, and the headlights were no longer always powered regardless of the key position. (IMG:http://www.914world.com/bbs2/uploads_offsite/images.thesamba.com-11380-1487356047.1.jpg) Issue number 3 was that my brake lights were always on and, when I depressed brake pedal, I was also getting some lights on the dash and power to the coil. I caused this problem when reinstalling the interior. I had screwed the plastic housing that holds the armrest through the floor. When I did so, I went right through the main power wire, nicked the brake light wire, and possibly exposed a couple others as well. I did a lot of troubleshooting and have a much better appreciation of the electrical system and also much more comfortable reading those wiring diagrams. Really helped a lot to blow it up to 3 foot by 4 foot and stick to the wall as me and a buddy worked through the circuits. Car is all back and buttoned up. Drove it today and very pleased! |
