On my 2002 Windsor, does the genny start off the chassis or coach battery? Thanks

On our 2000 Windsor, house batteries start the generator

Thank you

Coach batteries.

I believe that they start where ever the guy on the asm line hooked them up I have seen both ways and no reason why.

Mine starts from engine and my friends from coach. Lots of things at monaco were done weird with no reasoning I have a dynasty with all the executive options and nothing on the build sheet to say different just not what is on paper to what is as built

To be sure turn off the manual disconnect switches in turn and see which one disables the start.

My coach came, using the house batteries to start the gen. I rewired it in the rear run cabinet, to get power from the chassis batteries.
Probably not something you would want to do if your coach doesn't have a BIRD, or some other method of charging the chassis batteries while hooked to shore power.

I also rewired mine to the chassis battery.
The reason being was that the chassis battery is always at a higher voltage after 12 hours off the grid.

A friend's 5th wheel always had trouble starting his gen-set while boondocking.
He had lots of space so I wired a dedicated starting battery for his generator.

Our boat has a dedicated starting battery for the generator.

Our neighbour had a gen-set he could not start whenever the house battery was a little low.
He always would have to start the engine, boost the house battery just to start the gen-set.
We could never sort that one out, we relaced the cable connectors, remade the ground.
Must have been a bad starter as it would also blow the 150 fuse from time to time.

I changed mine after the first time trying out the AGS.

If you set up the AGS to start the gen when the house batteries get down to about 50%, there's not many amps left to run down that long cable, to crank the generator.

Maybe our 1999 Sig is the odd one out but we have two batteries for the generator, four AGMs for the house batteries and two batteries for the engine. At this point it appears this was an option or add on from the original owner we purchased rig from but sure looks like factory installed to me.

That’s the same setup I have.

Always Chassis batteries (at least should always be...).
If they were connected to house batteries and your boondocking, and run the house batteries down, you could not start the generator to charge the house batteries back up.

07 knight.............genny starts on house batteries...........i know this as the house batteries were drained once by a mechanic...............genny dead...........had to start the coach, let the house batteries charge, the fire up the genny...............i could have just held down the battery connect switch, but i wanted to make sure i got the engine started.........................only took a few minutes to get enough power to fire the genny................

I completely agree with you on this but for some reason they just did not do this all the time.
My two Monaco's both wired the Gen to the Chassis batteries.

Looking at a new Dutch Star with a friend (for him) recently, they said the 2019 Dutch Star starts from the House batteries, WHY?
