I have a ProStart replacement alternator for some recent GM SUV type
vehicle.  I was told it was a one wire unit, but it has a four pin plug in
addition to the output terminal.
Is the plug just for indicators or lights, or does this unit actually need
an external regulator?
Please email me direct if you cna help.
Thanks,
Wilson

No external regulator required.

that's a "CS" series alternator, which should help you finding
info/wiring diagrams etc.

good luck,

Re: Alternator Wiring





I recently had the local alternator shop fix up a CS (yes, Chicken S&&&)
unit
as a single wire application for my tractor, and the original plug cavity
was filled with silicone rubber, since those terminals are no longer
needed.

You normally just run one wire from the B+ terminal on the alternator to the
starter
terminal (not the solenoid) or to the battery +.

In the tractor application, the rpms are low, the alternator is in open air,
and current requirement is minimum, so maybe the CS will hold up.
So far, so good.
