Also, you should be getting charge from your alternator if you are connected to tow vehicle and the engine is running.
The Interstate vans do not use a converter. Steve's 2012 has a TrippLite inverter/charger, which is a better burner in it's own right!!!!!! Another piece of garbage brought to you by Airstream! They have intelligently replaced them with the Magnum MMS-1012 units.
Back to the problem.
I have a AI 2011 and now on an extended cross country trip. My house batteries not staying charged and have noticed a clicking sound in rear curbside rear corner and assume this is related to my issue. Has anyone had a similar problem?
It is entirely possible that the TrippLite has fried the batteries, which IIRC are mounted vertically in a metal box under the lounge on the passenger side. Randy's suggestion of using a volt meter to ascertain the battery voltage is a good one, as you really can't rely on the on-board voltage readings.
Do you have 120VAC in the coach when on shore power or generator? If not your inverter/charger might not be getting the 120VAC into it's charging section to charge the batteries. What type are they and how old?
That clicking sound might be your Battery Isolation Solenoid trying to connect the 2 battery banks if your house batteries are low and you are running the engine. Very difficult to determine where the sound is actually coming from.
You might need to remove the rear section of the electrical area (6 screws) to see the exact location.
Your lack of charge might be inverter/charger related. Only way to test this is with shore power/generator connected and use a DC volt meter to see if the batteries are getting any charge.
Check it out and report back.
