Greetings Everyone -
THANK YOU again for providing your experience and expertise. This place makes me very pleased that I chose a GMC Motorhome.
So I was working on the coach this weekend - examining things in preparation of replacing/upgrading the AC/DC electronics. Converter/charger, an inverter, and new 12V fuses...
I have two batteries up in the engine compartment - chassis and house. I expected to find a third battery back by the generator - a house battery - and plan to connect the inverter there. With that - it's a 5 foot cable run to nicely route cables to an inverter in the same cabinet as the existing electronics.
Well... I dug into the rear of the coach and was pleasantly surprised to discover two batteries back there!! 2 x 12V connected in parallel. And nicely installed too. Firmly held with a tiedown made from a piece of unistrut. Here's the questions:
I expected one battery back there... Was the factory configuration a single battery ?? What did the PO remove to squeeze a second battery in ??
I expect that two six volt batteries in series is the preferred configuration. Is there any reason that I should be concerned rather than pleasantly surprised ??
How does this affect my selection of a Progressive dynamics Converter/Charger ?? 45 amp or 60 amp or even larger ??
How does this affect any battery combiners that I've also been planning to install ??
I assume (didn't check yet) that these two batteries are also in parallel with the house battery up front. My memory certainly isn't the thing to rely on - but I sure don't recall seeing any heave guage cables connecting to the house battery up front. Could they be connected some other way ??
As from a previous posting - the chassis battery, the up front house battery, and this battery pack each have cut off switches on the negative terminals.
I've got endless questions - but that enough for tonight. Thanks again.
