American Coach: Indicator Lights - Fresh & Black Tank

[Bulldog96]

Long time reader, 1st time posting...I've got a 99 American Eagle that we bought last year, everything has gone pretty good so far. Today i noticed the indicator lights that tell you if the chassis batteries are fully charged as well as fresh water, gray, black and LP don't work. The surprising part to me is the indicator lights for the main battery work. I've checked all the breakers and fuses thus far and can't figure out why these lights won't work. It also appears the light right outside the main door does work. I have to assume this is something i'm over looking. Any suggestions???

Does all the other 12-volt circuits in the coach work? If not, the coach disconnect relay (aka the salesman switch) could be off or faulty. Depress the rocker switch to that relay to see if you can engage it. In fact, you should hear a “thud” when toggling it on or off. If you can’t hear it, that relay could be bad.

But if those display lights are the only system not working, I’d check 12-volt fuses one more time. (120-volt breakers shouldn’t affect this.) If your rig is like mine, there are multiple locations for fuses. I’ve got one fuse box in the bathroom and then a bunch more fuses located in the battery control center. And that’s not to mention the chassis fuse locations.

Bulldog,


Just inside the door, on wall between seat, there's 2 rocker switches, one is coach, other is chassis disconnect switches, when on a red light is on just above them.
The disconnect relays are in the battery compartment behind a panel on the left side...

The outside light could just be blown

have you found all the fuse panels?...
under the bed, on the left side of the front panel you'll see what looks like a cabinet door, the house 12 volt fuse panel is there, right next to the A/C breaker box.

There's also a 12 volt fuse box in the outside battery compartment, the one right behind the drive tires.

.....and one more fuse box under the dash panel directly in front of the steering wheel.

But since you have main (chassis) battery power showing, You may want to check the power inverter, it's located underneath the mattress. If yours still has the original Source Manager, there's a pop out fuse button on the side, but I think you'd have outlets that didn't work also if it trips....

Lots of knowledge here on those vintage American Coach, ask away!
