Joe,

It sounds to me like it would be worth checking your regulator as well. (As I understnad it), in a properly operating system, the regulator monitors the battery voltage and adjusts the field on the alternator accordingly. My understanding is that even a 100-amp alternator is not too much (although it is a bit of a waste) since the regulator is controlling its output. Obviously a 100-amp alternator does not "force" 100-amps into a system, it is capable of that, however.

This is true for external or internal regulators - and even the self-exciting 1-wire alternators. They ALL have a regulator in some form or another to protect your battery (and electronics) from overcharging.

Jack21 gave you good advice. Don't run the system that way. At as little as 15V, I've read you could actually have Hydrogen outgassing. That's not funny.

Let us know what happens.
