Alternator question

[pontiacgp]

Most of the "one wire" alternators simply have a rubber plug where the 2 pin connectors go. You can see it in the Summit pics,

What the hell area are you in that doesn't have an electric motor shop? They aren't as prevalent as they once were, but there should at least be ONE around. You get what you pay for in electronics. Buy the cheapest you can find, and it will last and/or perform accordingly.
The red wire with the craptastic connection is your charge lead to the battery. I would fix that before changing the alternator; it might be your whole problem.

took me hours and this is what I was able to dig up.....

Hopefully there description is right and it has the more open and better cooling 12SI case. I haven't had any 10SI case high amp alternators last more than a couple of years. The only one that lasted did not put out the 100 claimed amps, more like 70 or 80. Also that fan on the one you want is inferior this one, basically copies a 12SI fan. More amps need a bigger fan and more open back for better cooling. https://www.summitracing.com/parts/tff-7127nkb12

Right, most GOOD 1 wire alternators such as powermaster just have a plug in the alternator for 1 wire use. If you choose 3 wire, remove the rubber plug and put the wire in. Cheap 1 wire alternators eliminate all the parts associated with the other 2 wires and you're stuck.
