Same sound, different cause?
Have an outside 'beep' every 30 seconds whether on SP, on House Battery, or no SP with battery off. Sound is outside, behind Generator, but varies from underneath chassis to about two feet from bottom of chassis. When I get under the coach, the sound moves up. When I stand beside coach, sound moves under. Open driver door, beep is quieter. Closing door, volume returns. Checked under hood, sound behind generator set. (did check for genset warning lights, but nothing).
Comes from driver side only. Can't hear inside or on passenger side. Checked Instantaneous WH (turned off outside), heater, etc. Fridge off. Inverter too. Propane is shut off. With SP disconnected, and isolation switch off, house batteries Voltage dropped but beeping continued. Starting battery was fine.
Checked schematics, don't see anything inline.
Any other ideas?
