Chas

Great news!
I will be under the hood when I get home tonight. I was not sure where those fuses where located. Thanks for the info on the switch, my manual mentioned it's function, must have been a factory installed item.
I will let you know the outcome of my next adventure.

OK
I get home anixous to get some dirt under my nails. I look everywhere, cannot find the main 12voly pos & neg. fuses. I know that that the lead from the 12voly battery bank is dead, the univolt seems to work. When I pulled the univolt from the coach, I bench tested it and it was showing 12.8- 13.2 volts. I could not get a reading on the 12volt leg from the battery. I tried to follow the lead, it's buried under the coach.
Anyone with a 270 1985 A/S knows where the main fuses are? I looked at the front access panel, no nada.
I am thinking about running a new lead from the battery bank. A test showed that this works.

Thanks

In my coach, and I think most of the ones that use a univolt mounted by the passenger seat, the fuse panel is hidden. It is built into the riser that transitions form the main floor to the cab floor below the Passenger side seat. There is carpet covering it. If you use the left seat belt bolt as a reference, come half way down on the carpeted riser and give it a tug. It should be hinged. If you have the Magnetek brown style in the kitchen Battery Charger, the fuse panel is in the charger.

You could also have a bad battery isolator that is affecting the 12 VDC battery lead. It is normally under the hood on the right side of the firewall, and blue or red finned aluminum.

Thanks Brett for the reply

In my coach the Univolt is located under the rear coach next to the entry door. The fuse panel is located behind a hinged panel at the base of the coach, very accessable. Interesting enough, my wiring diagram shows all of the fuses etc, however, these are not standard fuses as I know them, I tried to pull off a black plate and no nada. Also my converter/ charger does not have a univolt name, however it is a 50 converter etc.
I will check the isolator. it is located as you described. I am just wondering if my coach does have a 50 amp fuses as mentioned in previous posts.

My A/S is a 27" Excella 1985, has 2 pull out couches( one front, one rear) that make into beds, rear bathroom. batteries located in side pull-out drawer. Just replaced house batteries w/ new deep cycle.

Thanks

OK,

Here is a dumb question. In the battery drawer is there a switch to disconnect the batteries from the rest of the coach? It will be a knurled silver knob with a ridge that points to the battery choice. Some are on/off others are on/off/all The last would be a boost setting.

Brett
The org. owner replaced the switch w/ one located inside thw coach. Tonight I will chech the connections, possible failure,anything is possible at this point. Regarding the booster... is that a seperate switch, there is a 2 legged switch of the solonid that has a small srew in the center. It is located on the back of the battery drawer.
Thanks
