<p>There is a diode setup in the isolator that prevents power draw from the coach to drain the chassis battery. It has to be shorted. </p>

<p>We can speculate till the cows come home. Nothing if the energizer is "on."</p>
<p>A bad cell would cause that till the batterys were dead.</p>
<p></p>
<p>My suggestion is collecting every schematic we both can. Way back in the day bad Alt. Vregs could kill batteries, but that could be tested almost anywhere auto.</p>

<p><span>old style solenoid- again be certain you have a good ground were it is mounted. Follow that ground all the way back to the battery negative post clamp. Could be a waste of time, but I got more time than money! Then I'd focus on the (+) operation.</span></p>

<p>Jack Wasmuth, I noticed there are several types. If yours uses a hardwired ground separate from mounting, I would check continuity to frame. Check chassis battery's condition it may have died on its own. Lastly I have seen configurations of house batteries charged off altenator that would do this and others that wont.</p>

<p>I dont have enough info to draw a conclusion other than the obvious the isolator is bad.</p>
