Balmar has introduced a robust Alternator Protection Module which helps to protect the alternators diodes and internal voltage regulator against spikes (clamping up to 60V) and sustained over-voltage conditions (beginning around 20V for the 12V version). The APM can absorb multiple surges of such energy and can absorb surges in excess of 200 amps without failure to continually protect your alternator. Visual and audible alarms indicate if the device has been compromised and needs replacement.\u003c\/p\u003e\u003cp\u003eBalmar APM devices provide intelligent, robust, solid-state protection in a small easily mounted package at the rear of the alternator between the B+ and B- terminals.
