2007 Dynsty Electrical issue
The RV has been parked with 50amp power to it for a month. Three of the four slide outs won't operate. Drivers side bedroom does. When I turn the ignition key on I get nothing, no dash instrument indicators, no transmission panel indications...nothing.
I checked the chassis battery switch and its ON. I put a charger on the chassis batteries thinking they are dead for six hours and nothing. The Aladdin system shows XXX for engine battery voltage. I try starting the ONAN generator but it won't start nor will the slide out for it work. Battery Booster doesn't work either. The start switches in the engine compartment are in the "Front-ON" position.
I can hear a very faint "PING" sound from just above the engine compartment Fuse/Relay box coming from a 12V unit that looks like a small speaker. It must be some kind of warning annunciator, for what I have no idea. (Having been around jet engines most of my adult life I say "faint" but it might be louder to most others.)
I suspect a relay is bad but don't have any idea as to which one is common to the three slide outs, ignition and generator.
Any ideas out there?
