Hey Anyone, How Do I Switch From A 3 Wire To A 1 Wire Altenator For A 283.

Doc here, :pimp:

Very Simple..

Just mount the new alternator, and run a 10 gauge wire to a PROPER Fuse link at the power terminal for the car Or the big terminal on the starter solenoid..

The old wires will get capped and insulated and tied back...not used..

Be advised..to excite the one wire alternator, you need to rev it a bit from idle to turn the regulator on..and your idiot lamp will no longer operate.

The regulator may be removed..Any of the larger RED wires that attach on the left side IIRC, should remain connected to each other..(should / Could be the horn relay and the main power buss support wires) but the others will not be used..It may be removed with the stock alternator..

There is no such thing as "Too Big" electrically..because the alternator says 100 amps, that is ONLY it's possible potental...The regulator (internal) will only run until the demand is met, than shut down..I.E. if a 30 amp load is imposed, it will put out only until that demand is met..then shut down..

The only other possible area of concern is upgrade the wire and add a fuse link..10 gauge wire and a 90 amp fuse link should do fine..

Originally, the car did not have a link..(the factory did not install them until about 1970) so you will be adding new..
