How do I switch to 1 wire alternator?

Once tripped, does the voltage sensing circuit charge the system according to amp/voltage demand and vary constantly or is the amperage and/or voltage a fixed number? That is what you need to ask Powermaster. If they say no, then don't do it. Oem's don't use a 1-wire...must be a reason.

If no, what would go wrong? Again, I'm a dummy and am just asking so as to learn. If damage would occur, why would they be selling it that way?

Once the alternator turns on it puts out 14.5 volts. The current level it puts out should increase with RPM just like any other alternator. I thought they used to have a graph in their ads but I couldn't find it on their website.

One thing to note is you CAN wire up their 1 wire alt to turn via the ignition switch like a regular alternator. Some models will run on 1 wire or 2/3 wire configuration.

How can I hook my one-wire alternator up as a three-wire alternator?

Some Powermaster one wire alternators (i.e., pn/n's 17127, 17294, 37294, 47294, 8002, 58005) can be hooked up as a three wire ...IF the vehicle is equipped with the two spade GM or aftermarket wiring harness. The Powermaster one-wire alternators have a black plug cover on the side of the alternator. This can be removed and the GM or aftermarket two-spade wiring harness can be plugged in for three-wire operation. See your alternator instruction sheet for further details.
