I have a small 10ah (4 Headways) aux battery and an Elcon DC to DC in my car. I don't even have power brakes, don't normally drive at night, etc ... so for the past 8-9 months, haven't had any issues with running low on aux battery power.
Last week, however, after charging up, the car didn't start. When I tested the 12v power, it was 9v ... one of the 4 Headways was at 0v ... dead. I'm not entirely surprised at this, since the cell was one I had revived from the dead. However, I wasn't sure if perhaps the DC to DC failed, and that's why this cell died. So I have a couple questions: Is there a way to ensure that the DC to DC is still working? Will it be "on" just being connected and show a voltage across the outputs? Or do I have to measure it indirectly: the aux battery should show a higher voltage after the main contactor closes?
