Using the original wire on the alternator side of the warning light to get to #1 terminal on the alternator. Which I believe is the correct way to do it. For some reason I'm only getting 7 volts to Field terminal (#1) which is not enough to excite the alternator. Don't know where the 5 volt drop is coming from as the wiring is good back to the warning light. Could the warning light be dropping that much voltage?
