My wife & I stored our 2008 Canyon Star for a week in our garage ... I went to finish winterizing it today and found my coach batteries "Completely" discharged ... when I put it away last week we hit the battery disconnect and thought all was ok till now .. I started the engine in hopes of charging the coach batteries (let it run 1/2 hr) nothing, then I tried the battery "Boost" to attempt a generator start and ... again nothing ... any thoughts as to what to try next or do I need to hook it up to an AC source to get the batteries charged again before I can use the coach ?? ... seem svery strange ... Help .. Don

I was told years ago (by Pappy at North Trail), that there is a certain sequence to the battery thing: 1. Coach batteries; 2. Generator; 3 Engine batteries.
If the coach batteries are dead; plug in the coach or "jump" them from another vehicle. Then you can start the generator. Then you can "boost" the engine: and Pappy emphasized ONLY in that order!

Hi donwilli,
Please, do not leave the coach batteries in a discharged condition. Whatever you do, do something to get the batteries charged. You will need to bring the charging power to the batteries or the batteries to the charging power.

If you have a charger and an A/C source of power, the easiest thing to do would be to use the charger to charge up the coach batteries. Check the water, in the batteries, before you charge them.

If you have a charger, but no A/C source of power, consider taking the coach batteries out of the coach, to a place where they can be charged. Because you are winterizing the coach, maybe you could leave them out of the coach for this winter? After charging the batteries, let them sit disconnected for a week. Check each cell with a hydrometer to ensure the batteries are still good. Even with a new coach, you could easily have an internal short or dead cell. Do not let the batteries sit on the ground or on concrete for any length of time.

For my Newmar coach, when I turn the coach disconnect switch to off, everything is really off. Yours may be different. After this is all sorted out, consider running some tests, once you get fully charged coach batteries in the coach. You either have a draw, even when the switch is off or a bad battery(s).

Might be a bad battery, could be that it is not disconnecting completely. If it's a bad battery it will run down even when it is connected to nothing.

Soricobob & Gary KD ... thanks for the tips ... My wife & I are woerking on the coach today (again) ... one more question, we're trying to winterize the coach and the whole house water filter has a note to remove the filter and "replace the glass bulb" before winterizing ... I don't have a glass bulb and my pump won't pick up the antifreeze to pump through the water system ... could this be my problem ? ... thoughts ... Don
