On my Bailey Autograph 765 the alternator doesn't appear to be charging the leisure battery, or running the fridge on 12v while the engine's running. Has anyone got suggestions? (Sorry if this is covered elsewhere.)
Charging the battery is fine when we are booked to the mains and as far as I can tell the battery itself is in good condition. I've checked the voltages in various conditions as follows:
Battery, off-charge: 12.5v. Left for 48 hours, all lights on: still around 12.4v . Plugged into mains hook up, charging: 13.6
Engine on, fridge NOT on: 12.5v (implies not charging?) Engine on ,fridge on: 12.4v and dropping steadily down to below 12 before I decided it clearly wasn't right.
My understanding is that in order to charge ,the voltage across the battery from the charger must be more than 12.5, let's say 13.5v to 14.4v. My dealer is sort of saying the bare 12.5v we see is ok. I haven't yet convinced him there's a problem. But as it is, I need regular hook-ups and can't run the fridge while travelling.
All thoughts welcomed.
