Converted to an Alternator today
Well, thanks to Jerry(C5Farmer), I was able to get a set of alternator brackets and get it installed on our 62 tempest today. With instructions from M.A.D. electrical, the job was relatively simple. I went with a 94 amp internally regulated alternator. It is a 12SI series that is clocked at 9:00. The application is a 85 Buick Rivera with a 307. Plenty of juice to keep the electric fuel pump and electronic ignition happy now. The headlights don't look like candles anymore either. I need to go back and retape the wires, neaten it up a little bit but I was primarily interested in getting it functional today.

Alternator
Andy, Looking good and the increased charging power will make your Tempest a better daily driver. Glad all the pulleys lined up for a nice, clean installation. Any special reason you selected the Buick Riv 307 alternator?

I used a one wire alternator on my 62 Lemans and ran the wire along with the temperature sending unit wire along my valve cover back to the starter. Looks much cleaner. 9000 miles later, no problems. My electrical parts supplier made the wire to the length I told them and it looks factory.

Amp gauge
Gary, What did you do with the Amp and voltage regulator wires? I used a one wire alternator on my hot rod Tempest and wired it directly to the battery. The amp gauge wire was left hooked up and the wire disconnected at the regulator. I installed a volt meter and it always show a charge of up to 14 volts.

I chose the 3 wire because the reasons Mark outlined in this document. http://www.madelectrical.com/electri...hreewire.shtml All of the wiring in the photo isn't for the the alternator. Some of it is for the front light harness, and the rest is for the relay I wired in for my electric fuel pump. Basically the relay is connected to the oil pressure sensor, so it has to see oil pressure in order to complete the circuit for the pump to being pumping. Basically a safety item. If the car were ever wrecked and the engine shut off, it would kill the fuel pump keeping it from pumping fuel and possibly causing a fire.

I like the idea of wiring the fuel pump to the oil sensor wire, good safety tip! |
