Charging EI backup battery ?
I purchased duel ignition units for SDS CPI system. Ross sent me a schematic for a 7AH battery to power the second unit as backup. My question is, can I use the main buss alternator voltage to charge TWO Earthex batteries. The second to power one ignition as backup if needed.
