adding relays
Anyone install relays for the headlight circuit, or any other circuit, so that full voltage is obtained? I want to but need some info. Was planning on getting relays from madelectrical.

I installed headlamp relays (along with xenon lamps) on my wife's 62. I installed them if the front of the car, close to the headlamps to minimize any voltage drop. In my case I ran a separate 12 gauge supply wire from an auxillary fuse panel under the dash to the relays. I cut the "normal" high beam/low beam wires and used them to trigger the relays. In my case I was only getting about 9-10 volts to the lights and the difference when driving at night was amazing.

If yopu are still using a generator (to keep the tach turning), all you will get is 9-12 volts at idle. It should increase to 14 volts at 2000 rpm. If you use a high output alternator, you can get 13-14 volts at idle.

I added relay's last weekend! WOW it works well!
I did it all with the advice and parts from from MAD. I Use an alternator, I added a CN1 (the terminal block) to the firewall and added another one on the little vertical lip just below the top of the fender just behind where the hood support folds into. The firewall terminal block is for car/dash accessories (like AC/heater) and the Fron Terminal block is for headlights, accessory lights or fans. The high beam and low beam wires run just below and are easily traced from the high beam low beam switch, just follow thier instructions, they work stunningly. I added a fulable link to power up the dash from here and added a "shunt" across the amp guage (as reccomened by Mark). He is a great resource to talk to if you can get through (guess I got lucky)
I am really pleased with everything, sure you will be too.
