Ultra Supreme Where is 2nd house battery located?

[Ray Porter]

I have a 2003 Gulfstream Ultra Supreme
2 batteries under front cover in long battery tray!
1 battery is for engine
1 battery is house
with both negative cables disconnected!
I still have power at the generator 12 volts
Not plug in to shore power
I have been told by an RV repairman that some manufactures put one under the door steps?
No batteries in any compartments ! Battery on/ off (2) switches in right front compartment.
The battery i can not find is bad and needs to be replaced!
I need someone with this model to tell me where the 3rd battery is please!
Under door steps electric motor and tons of foam!

Track the wire from the generator. I bet the battery is close by.

Hi
I have a 2004 Ultra Supreme. Ours has 3 batteries in the long tray in front. 1-12 volt Engine Battery. 2-6 volts house batteries wired in series.
no other batteries that I know of.

If plugged in, you are getting 12vdc from the CONVERTER; (I made the same mistake once, had to get the wife to point it out as I scratched my head :-)

Thanks I think that something like this happened to me? I don't think that I was pulg in to shore power ? inverter may have had a little power stored in a capactor or coil? don't know? Just drove me batty for a while. New house battery and everything seams ok!
Thanks everyone for the ideas!
