Default No charging

We took our first trip in our new bird this weekend. I have been working on the interior for the last 45 days and have started her a couple of times. Last monday I went to start her and nothing. The PO told me the batteries were fairly new, but I'm finding out he told me lots of stuff. So I went and replaced all the batteries on the coach with new cables, started right up. We camped from thursday to sunday with 50 amp service and this morning, dead batteries. Jump it, drove home and the alternator has recharged the batteries. I checked the voltage with the coach off, 12.3 volts. Started the generator and still 12.3. Checked the output of the charger 13.1. Followed the leads to some kind of a bus bar 13.1. I don't know how to follow the charge to the batteries after this. Any ideas?
Thanks Kip

Kip, Those bar looking things in picture one is of shunts. They measure voltage flow/drop.

From your Photos it looks like two corrugated plastic lines go below the shunts down to the black plastic covers. Have you checked the connections? Problems often get resolved by tracing and cleaning the connections.

Kip,

That Power Source 75 Amp charger should normally have an output of about 14.2 Volts - make sure it’s getting power from the 120 volt outlet it's plugged into.

I did check power to the plug its good. I thought about the plastic connection your seeing but I've got 13.1 after the plugs where it attaches to the shunts. It's from the shunts that I can't see where it's going

Hi Kip,

13.1 volts doesn’t sound right to me. My 91 Bird has 2 Power Source 75 Amp chargers. Normally only one charger is connected to the batteries but I have the option of connecting the second one to the batteries by flipping a toggle switch in the cord bay to the “High“ charge position.

Either one of my chargers puts out 14.2 volts or more anytime they are charging the batteries and when charging heavy they heat up enough to turn on their internal cooling fans. Even when my “High” charger is not connected to the batteries it’s still powered up from the 120 volt outlet and it has an output of over 16 volts with no load on the output terminals.

I'm not big on electrical so please add your thoughts to my comments;

A charged Battery by itself can have a reading of 13.4 volts (when fully charged). While its is being charged it will read higher to 14.5.......... 13.1 does not prove the charger is working only that the battery is charged/full. Is there any green corrosion or signs of heat?

Hi Kip,

I don’t know if it applies to your coach but page 149 of the 1988 wide body owner’s manual found here on the Forum has a partial Battery charge circuit drawing.

http://www.wanderlodgeownersgroup.co...s%20Manual.pdf

That drawing shows the output of the alternator as being tied to the same post of the Alternator Ammeter Shunt that the battery charger output is tied to. In that circuit the power from the alternator AND/OR the Battery chargers goes through the same Shunt and then through the Battery Charge Ammeter Shunt before it gets to the batteries. If your Bird is wired that way it would seem that if your charger was working right it would be charging the batteries through the same components that the alternator is.
