This a new prototype that my alternator supplier is making. This unit is based on the new Nippon Denso "Hairpin" alternators. It is 160 amp, and produces extremely well at low rpm. The electrical pulses have very little ripple, so should do very well with electronic modules. All of the major car manufacturers have gone to this style of alternator. I will be testing this alt. on my camping rig. with a 50amp Dc-Dc charger to charge my lithium battery.
