You have probably heard this before but from my experience, the PROBLEM
sometimes is very simple instead of going off the deep end. It is usually a
simple fix with these BIRDS. Just start with the very basics first
etc.......good luck.....

If the charger reads (or is expected to read) 14 to 14.5 volts, then it must be
a "smart" charger. If it is a smart charger, then it should show a high voltage
when connected to a discharged battery, but with no battery connected it should
automatically show a lower voltage.

If the charger is not a smart charger, then disregard.

In either case, you might try disconnecting the the battery bank(s)from the bus
and borrow/beg/rent/buy a 40-50 amp portable charger that has a battery
reconditioning function to see if you can bring the batteries back. I've had
some good luck with this, getting extra months or years from batteries that had
experienced a complete discharge.

The corollary to trying a reconditioning charger on the batteries is to try a
different battery on the charger. Any available partially discharged battery
connected to the bus charger will tell you if the charger and isolator are
working. Use a specific gravity tester to see if the battery gets charged.
(Also, use the tester on the bus batteries to see how badly discharged they
are.)

Finally, going back a step or two, did you check the voltage at the batteries
with the charger on/charger off? If the voltage at the battery post(s) does not
go up when the charger is turned on, then there is a problem with the charger or
between the charger and the batteries.

Load test each battery individually, possibly a bad cell, then recharge, with a
shop charger.

Make sure that your main DC switch by the door in ON

Make sure that you AUX BATTERY on the dash is ON



See if that will work



I found out the hard way these need to be done on my coach to charge both bank\s of batteries

Go to Walmart and buy a cheap Hydometer and check your battery water. Simple
easy to use and you can see if what condition your battery is in. Good site to
use if not familier with what a Hydromter does and how to use it.
http://www.batterystuff.com/tutorial_battery.html

[Chuck Wheeler]

Most smart chargers will operate "current limited" into a discharged battery so the voltage will only be as high as possible within the current limits of the charger. Once the battery terminal voltage gets to the point that the current is below the charger's rated current limitthe chargerwill go to "voltage limited" operation. At this point you would see the voltages you would expect. If you immediately see 14-15 volts across a discharged battery then you have a weak or bad battery. A good discharged battery has a very low internal resistance. As batteries age this internal resistance increases.

Any available partially discharged battery connected to the bus charger will tell you if the charger and isolator are working. Use a specific gravity tester to see if the battery gets charged. (Also, use the tester on the bus batteries to see how badly discharged they are.)

Finally, going back a step or two, did you check the voltage at the batteries with the charger on/charger off? If the voltage at the battery post(s) does not go up when the charger is turned on, then there is a problem with the charger or between the charger and the batteries.

Sounds like you did the same thing I did. I have the Progressive Dynamics 80 amp charger, I found out this week that when there is no power ti the charger it goes in to monitor mode.My batteries were doing the same as yours. Out of 4 have two bad. The voltage dropped to 0 and suffocated the plates. Take yours to a parts store that does free battery testing. just checking for voltage on indicates what it is charged to not the actual condition of the battery need a load to do that.
