1 wire alternator swap

[RJRENTON]

I believe the big 120 amp alternators from the 70s 80s were rubber mounted.. requiring a very large ground trap.

It's an over voltage (PRV or Postive Reverse Voltage) of the individual diode being exceeded, issue NOT a "ground trap"...what ever that is...???

Yes, but once you connect the original black wire to the alternator stud as well as running a 4 awg wire to the + battery post your amp gauge becomes irrelevant. It’s also a good idea to put an inline fuse between the alternator and your battery in your new wire.

There are other more serious concerns about that “under-hood” by-pass that those who promote it don’t talk about, especially without any circuit protection at all. 4ga directly between the alternator and the battery?

Haha good point. Ground "strap" .

I believe "most" alternator's have DELTA (no neutral point) connected stator windings, although maybe some of the Leece-Neville or high amp GM 12SI units have WYE (the end point is the common connection) connected stator windings. This neutral point is used to operate a field relay/indicator light system.....WHAT is this ground strap you noted?? There is nothing grounded in an alternator except the negative end of the negative diodes array. Please describe....
