1938Re: battery chargers and dc dc converters
- Apr 10, 2006Tha bad news about the Solectria DC-DC converters is that it puts out
only 12 volts. So your headlights will be very dim. You need one that
puts out around 13.8v.

batteries it is programmed for. Is is 120V or 240 Volt? I am looking
to buy a 120 volt and get it reprogrammed for my car. Let me know, if
