Will be putting coach inside storage 2 months. has a 25 amp plug I will be hooked to I will go down to 1 inverter set, electric aquahot to 50 never goes below 60 in the hangar it will be in, question is do I leave the engine start batt switch on so charge will bleed over to it. AND do I turn off main coach power at exit, or will the main just defeat all I just did thx in advance

If you have shore power just leave it plugged in per normal. As for the engine start to battery switch I think you are referring to the switch that toes the house batteries to the chassis battery in a no start situation. This is mot a method typically used for long term connection of the battery banks. My two coaches this has been a spring loaded switch that only engages while you hold it. There are devices made for maintaining the two bank together or simpler to just put a separate trickle charger on the chassis battery.

sorry I wasn't clear I mean the chasis 2 battery switch at the rear compartment outside the coach that is next to the def fill thx will the inverter still charge those when disconnected during storage when plugged in to 25 amp plug

A subject of discussion in another thread...several said no...I said Ted Cook told me yes. Call Entegra and ask, or use a trickle charger, to be safe.

got it dave I will put an end to it by taking a test meter there test it kick it off then on plug in then unplug shouldn't be questionable then. thx

That should work, but my understanding is that the inverter moves charging towards the chassis batteries after the coach batteries are fully charged. If the inverters truly do operate that way, and at this point I don't know who is truly correct, you'll have to make sure your fully charged topside.

You know, the interesting thing is there are a few things tied directly to the chassis batteries and consume power. If the inverters didn't work that way, why, when you are on shore power for long stays, wouldn't you have to do something to recharge your chassis batteries. I haven't found that need to be the case. My experience is that they stay fully charged day to day.

I was told years back at a Spartan class that the Allison transmission has a memory and learns how you drive for proper shifting and economy. If the chassis power is turned off that memory is erased.

I put a float charger from Harbor Freight on my Chassis batteries as the TS inverter did not charge chassis batteries and left both power switches turned on .

When I did that test on the TS, I charged overnight, unplugged, tested with a volt meter, turned the headlights on for about 20 minutes to draw the battery down. Tested with a volt meter at the batteries, then plugged in and tested again. The TS failed and I rechecked every few minutes for 20 minutes and no increase in battery voltage. I hope the Entegra jumps to 13v when you plug in.

Please do post what your test comes up, I am anxious to find out if the inverter does charge the chassis batteries, I sure hope so.
