Hi

I purchased a sca duel battery kit some time ago and when I have come to fit it I have misplaced the fitting instructions. No problem give it a go anyway. Now it fitted and the main battery charges OK but does not seem to charge the second battery.
I can hear the relay clicking on and of when I unhook the second battery, I have a duel battery monitor in the cab so I can tell its charging the main. Anybody got a copy of the fitting instructions or if you have one fitted can you tell me which battery has the lead running from the isolator that is painted red.
