Hello,
I recently purchased a high-output (140 amp) alternator from AES (thanks to the info provided by OutlawMike), and am getting ready to install it in a '96 Corolla. The new alternator has a main power connection, and a 3-prong female socket. I plan to run 2-gauge welding cable for both the power and ground, but can't figure out how to hook up the ground. Are these alternators usually grounded through the frame, without any wires? I can't see any wires emanating from the current (stock) alternator that could safely carry 70 amps (its full rated output). I'm just looking for the best way to safely ground the new unit.


thanks!

 

You don`t need to ground it, just hook it up and your done. Just make sure that the engine is grounded to the frame and from the frame to the body and then to the battery, as long as those grounds are good you won`t have any problems.
