Lower output in measured DC Amps. For the more electrically savvy, higher ripple as now you have less than 6 diodes rectifying.
On a better quality and higher output alternators, like balmar, amptech etc, you can see them built into the body, shiny circles with numbers on them, sometimes 3 are marked with red dot and 3 are marked with black dot indicating polarity. There is a great alternator handbook in pdf floating around on the web. URL escapes me. It gives details of all types of alternators. On a cheepo and lower output alternators they might be in a form of an IC. (integrated circuit) The issue is the back emf which all inductive parts have. If your alternator has no place to dump the current and you disconnect the batteries while engine is running, high voltage spikes are generated. If diodes are not specified to withstand these voltages which could be in the order 500V or higher (usually the case with rectifying ICs as they are cheaper and smaller form factor) they tend to fail. Hope that helped clarify what’s going on inside the alternator casing.

I am, electrically challenged, admittedly. Bill Walker CnC 36 Sent from my HTC
