I've been a fan of the 1 wire setup for a while but was reading an article on an electrical website about the shortcomings of the 1 wire setup, and it takes me back to the theory of "GM did it that way for a reason.."
I need to wire mine back to a 3 wire...
Can't remember the site, MAD electrical or something.
Both 3 wire and 1 wire have pros and cons. I only run a 3 wire setup. Here is a link to the Mad site that has excellant Tech articles on both setups as well as other excellant electrical systems articles
YOU CAN CHANGE A THREE WIRE TO A ONE WIRE AND VISE VERSA EASILY. IF YOU WANT A ONE WIRE UNIT ALL YOU HAVE TO GET IS A SELF EXSITING REGULATOR AND INSTALL IT IN THE ALT. AND IF YOU HAVE A ONE WIRE ALT. YOU CAN GET A OEM REGULATOR AND HAVE ALL OF THE VOLT SENSING BENIFITS THAT IT OFFERS.
So I have the one wire and I can tie off the old wires that went to the alt them run a wire to either the battery the starter post or to the horn relay and be done with it right. Then just hook up the battery as normal with the positive cable to the battery and the small wire to the horn relay. I have the convervion plug for the voltage regulator. I could later return to the 3 wire if I wanted to. Right?
HEY BUD, IVE GOT A 68 WITH A 1 WIRE SET UP. ALL I HAD TO DO IS TAKE A WIRE FROM THE EXISTING HOT LEAD THAT CAME OFF THE 3 WIRE SET UP AND START THE ROUTING DOWN BELOW THE BRAKE BOOSTER, UNDER THE DISTRIBUTOR, ALONG THE INSIDE EDGE OF THE VALVE COVER TO THE BACK OF THE ONE WIRE ALTERNATOR. THEN I DISCONNECTED THE PLUG TO THE REGULATOR AND ZIP TIED IT OUT OF THE WAY. THE 3 WIRE HARNESS IS TAPED OFF AND TUCKED NEATLY AWAY BEHIND OR JUST BELOW THE BOOSTER. ALL WORKS FINE, I LIKE THE CHROME ALT ALSO SO I THOUGHT I WOULD TRY TO HELP. I USUALLY READ BETWEEN 12.9 AND 13.7 VOLTS AT THE BATT DEPENDING ON THE CHARGE IT HAS.
