ON CERTAIN MOTOR HOMES EQUIPPED WITH WITH A 3.2 QD CUMMINS ONAN GENERATOR, THE GENERATOR’S INTERNAL CONTROLLER MAY FAIL; HOWEVER, THE ELECTRICAL CIRCUITS WOULD REMAIN ENERGIZED. INCLUDED IN THESE CIRCUITS IS THE ELECTRONIC PREHEATED ELEMENT WHICH AIDS COLD STARTS AT AMBIENT TEMPERATURES BELOW 0 DEGREES CELSIUS. IN NORMAL OPERATION, THIS CIRCUIT IS ENERGIZED NO LONGER THAN 120 SECONDS AT 30 CELSIUS. IF THE CIRCUIT REMAINS ENERGIZED BEYOND THE DESIGNED PERIOD, THE PREHEATED ELEMENT CAN OVER HEAT.
