Batteries dead...won't start

If your chassis batteries are testing 2 and 3 volts, I think you have found the problem.

How can you say that 100% sure, without testing them first? Does anybody on this forum know if there is a draw on the system? Wouldn't you yourself want to start with exploring the condition of your battery first, before spending money? Is there a problem with his charging system? See, things that we all don't know, not being there....

I'm not making fun or poking at you, I've noticed almost everybody on this forum goes right for the deep end of the pool first. I am not a parts changer, I'm a technician, find the real issue, and fix it at the lowest level. And do it on time, with the least amount of funds. I'm not rich, but because of this style of maintenance practices, I'm not broke either.

..Good points, but please re-read what the original poster said in the last post:

....I pulled the chassis batteries completely and measured them independently. One has 2 and the other has 3.

..If the batteries were pulled and separated completely from the chassis and still measured just 2 or 3 volts....Sorry, once a battery is depleted that badly, it is most likely not ever going to take a charge and come back. At least if it does, its life will be very short before this happens again. Especially since we're talking about batteries that are already at least 5 years old (2009 coach?). If they were newer batteries, maybe, but not ones that are already that old.

I agree that more research, diagnosis is eventually going to be needed to determine what may have depleted the chassis batteries so badly. However, at this point, regardless, the next order of business is to start looking for deals on some new chassis batteries.
