I've been running a 10si for several years without a problem using just the stock amp gauge on my '40 with a 235. I don't draw that much amps but what happens if I discharge the battery a lot? Like if I have starting problems and have had to crank it too much. Or, if I left the lights on for a while? Would that make the alternator put out its max trying to charge the battery?
