No 12v in coach when switched to battery?

[parkgt]

I have a 2006 Great West Van with an upgraded system including solar and two AGMs. Been working fine for the last year plus since upgrade.


Today I pulled it out to find that the 12v side running on 12v is dead. When plugged in 12v works fine. Batteries are up have 12v on both side of my Blue Sea disconnect but no 12v to coach when not plugged in.


Suspecting failure in the OEM Progressive Dynamics Charger/Inverter. It has never been replaced; not sure of the model since it is buried in a wheel well housing. It is the common one for that vintage van. Does this sound like a reasonable place for the issue.


If there is no quick fix, is there a suggested replacement that will fit the same footprint; not much room in there for much bigger. Is there a newer Inverter/charger that would take better care of the AGMs? The two Full River AMGs are topped off by a Victron charge controller when out if that makes any difference.


Any input appreciated.

Thanks,

Solved: Missed a circuit breaker between switch and inverter.

Thanks for posting the update / solution. Great that it's all working again!

Now that the issue is solved, I hope you don't mind if I mention more accurate descriptions of components. The solution should be easier to find in future searches.

Progressive Dynamics units are known as Converters or Converter/Chargers. Converters change (convert) 120VAC to nominal 12VDC. - described here: https://www.progressivedyn.com/

If all original, a 2006 GW van could also have an Inverter as it was a listed Option back then. Inverters change (invert) nominal 12VDC to 120VAC. It's probably worth noting that GWV listed an Inverter as an option and not an Inverter/Charger which combines Charging and Inverting alternately not typically simultaneously. Hybrid Inverter/Chargers can do both simultaneously.
