I've been parked for 3 days and the kitchen panel light going into amber for "battery" level running everything it does, and when idling the engine for 20-30 minutes that light returns to green WHILE THE FRIDGE/RADIO ARE RUNNING, and after another day the amber light level returns, while the fridge/radio are running. Idle is at 600rpm. I'm using the UB12220 wheel chair batteries (4) set up and have no electrical level monitoring gauges to actually tell me any specific information. I have a '90 Subaru 2.2 motor with an SVX alternator (95 amp) in the system. I also have the 1315 separator in my main battery box. Vitrifrigo fridge. Bob Stevens '87 Syncro Westy |
