We're currently in a marina, on shore power with the battery charger on.. and the starter battery (2 year old Victron 110ah) has suddenly died - showing less than 2v! and reducing 0.01v every 5 minutes).
We had our Valeo prop shaft alternator bench tested recently by a local electrician and put back. When he replaced it, the switch for the generator had been reversed.. ie 'on' was now 'off' and vice versa. I suspected the diode had been reversed or damaged in the re-istallation so disconnected the prop alternator hoping this would stop the drain - it didn't - so maybe it wasn't the problem.
The Mastervolt Chargemaster 24/100 has had intermittent display problems lately although still keeping the house batteries at 100% throughout.. could that be related?
I am at a loss at what investigate next - any suggestions?
