1997 Winnebago Vectra Drove home. Turned MH off. Wouldnt start.Odd Part is:1. battery cables good and have continuity.2. Took battery and had it tested. is GOOD3. Get no power to front of bus. No horn, no lights, and no ignition.HERES THE ODD PART: WAS TRACING THE CABLES FROM BATTERY AND TRACED THEM INTO THE BOX MARKED "BATTERY MODE SOLENOID AND DISCONNECT RELAY LOCATED IN SIDE HERE"Opened that box up and when I would hit try and reset the "Coach Breaker Panel" fuse... I could at times get the lights , horn , and even ignition to turn on. But when I would try to turn the key to the start position... wasnt enough power. As i said the battery has been checked and is good. Now im back to where nothing will come on.thanks in advancejohn

loose/corroded battery terminal(s) or connectors? do you have a salesman's switch that got flipped? what happens when you use the 'battery boost' switch? have you tried substituting one of the 12v coach batteries to see if it will start?

What is the actual battery voltage? Battery could have shorted internally.Battery connections may "look" great but be corroded where it isn't visible. The only real way to know is to take them apart.

ShastagaryI'm looking at the engine battery. Are u saying it could actually be the "coach battery panel fuse?" As well as one of those solenoids in there behind the panel. I took the battery out and had it tested...it showed to be good

Now power to engine/lights/horn battery is good
