I have a 12/12-30 dc to dc charger hooked up to my battery in my car. It has worked perfectly for three months but yesterday it started cutting out. It would work for 5 min and then input voltage would drop and it would turn off then input voltage would go back to 14.2v and it would turn on again and repeat doing this over and over again.
i have 6awg wire ran from the battery to the unit and from the unit to my house batteries, fused at the starter battery and the house battery through a lynx distributor. Not sure what the issue could be so any assistance would be helpful
