Loss of DC Power

[grampakoot]

I have a 1998 allegro bus.
Washed off battery bank this am..looks like I blew something...no DC power...no pump...fridge etc.

Fuse bank all ok
Any ideas as to how to reset???

I can't find where battery cable fuse is. I am still hoping someone can pinpoint where I look for breaker or fuse on 1998 Allegro Bus.

If all you did was wash off the batteries then the problem is with the batteries. You may have shorted the batteries depending on what you used to wash them. Take voltage readings at the batteries to make sure they are fully charged and make sure your connections are tight.

First: Meter the batteries, Use a digital multi-meter and measure AT THE BATTERIES, or, i you have one a 12 volt clip on trouble light (I have 2) to make sure the batteries are not, as suggested above, toast.

Now,, Even though most tap water is conductive, it's not that conductive that it would blow fuses or trip breakers in a 12 volt system. 120 volt perhaps, 12 volt no.

But you may have tripped something, specifically the AUX battery disconnect, Somewhere in your rig is a switch may be a toggle or a rocker, and you need to be very very quiet as you toggle it first to OFF or STORE, and then to ON or USE

you should hear a very clear CLUNK from somewhere inside (Unless you have a rotary switch near the batteries) both ways, If you only hear a clunk one way GOOD NEWS, it won't cost anything to fix, post for how.

Next, if that does not work, take the aforementioned test device (Meter or lamp) and follow the power.. now the lamp is best here cause the reading is easy to take (no need to actually look at it)

First, Negative to battery negative (with lamp it matters not which lead is negative but for tradition's sake, if it has one black and one red, it's the black) Positive to positive on the battery.. Light.. good, move black lead to chassis, Light good, no light bad ground connection, check both ends.

Move red lead out to the wire, then on to the other end of the wire, then on to the other side of whatever is there. and so on till you no more see the light, problem found.
