Guest Rustler Posted August 17, 2010 Share Posted August 17, 2010 Hi.... Just replacing my RH/Drv headlamp units with LH/Drv units for the French MOT. I'm looking at fitting uprated 100w H3 lamps in place of the original 55w on the main beam (FLOOD) side "RS2000 Type" headlamps. Question is, will the 70a alternator cope ok....??? 2 x 100w + 2 x 60w main beam = 320w, IS the output of a 70a alternator 840w ??
