Ratings & Reviews
I installed the unit to charge an auxilliary battery in a 1940 Cadillac Lasalle. After making sure all the leads were secure, I tested the charge at each battery. The primary battery was receiving a charge of 13.6 volts from the alternator, whike the secondary battery registered. 13.2. The unit seems to function as advertised
