Do you have a main electric fan in the place of the engine fan? Or, are you talking about the ACC fan (In front of the condensor)?
The deforster takes a boat load of power, as does any resistance heat device. If you a multimeter or voltometer, check the battery voltage: Engine off Engine at idle, no loads Engine at 2000rpm, no loads 12 with engine of is normal. With the engine on, it should be between 13-14.5v |
