Alternator Failure

[mv031161]

This is what happens to your brand new Oddissey Battery when your Suzuki Samurai Alternator Internal Voltage regulator fails and it ouputs 18 volts! I will reccomend a B&C Voltage Regulator to the RV8 Owner next!

From what I've gathered from aero electric, a crowbar over voltage module would have saved your battery

The B&C voltage regulator referred to in the original post has built in over voltage protection, which I believe is the point being made there.

Sorry, but what is a "B&C''.

Does anyone know of a supplier for a "free Standing" 14 v system over voltage protection module aside from the built in models usually included with the Alt or external regulator?

How does that wire in ? Has some pretty small looking wires on it. The wiring diagram did not open up on the B&C site.

Dennis, this module will protect an externally regulated alternator. It is connected to the field wire between the circuit breaker and regulator. When it senses high voltage it shorts the field circuit to ground which pops the breaker taking the alternator off line. This happens in milliseconds.

There is a way to use the module with an internally regulated alternator but it requires additional components. Details are in Bob Nuckoll's book, The AeroElectric Connection.

Or an overvoltage annunciator. Second most critical to a low oil pressure annunciator. Looks like that battery cooked for a long time.
