1 more cs130 wiring question
i have a 1984 cutlass with a chevy 350 engine ,i added the serpentine set up off a 91 1500 is it okay to hook the thick red wire from the plug to the back of the alternator and run a heavy guage wire from the terminal in back of the alternator to the battery also i spliced the brown idiot light wire directly to the L wire on the plug is this correct. i turned the key to the on position to see if the light came on and it did so is it correctly wired thanks

Not sure about the wiring, but did you switch out water pumps. With a serpentine system you have to run a reverse flowing water pump. Just want to make sure before you have a heating problem.

I believe the 'F' and 'L' leads on Doc's diagram are reversed. The 'L' lead should be used with a lamp or a resistor in place of the lamp, and the 'F" should be a system when there is no charge lamp in the system. This is how an automotive electrics tech explained it to me and how I have it hooked up on my rod - has been running quite a while now with no problems.
