Faulty ground was ruled out. Batteries with an open cell can present with a fairly high voltage after charging but the voltage will plummet on engine start. (Note- Starter motors can fail and draw enormous loads from a vehicle’s battery before total failing). So, what was the observed battery voltage drop during engine start on a fully charging the battery (12.8)vdc?  Next, good batteries can drain down if there is an indirect high resistance (paralytic) short to ground in one of a vehicles electrical systems, or worse, a wiring harness. I did’t see a resting amperage check with all systems turned off and doors closed. If it’s over 0.1 ampere, there’s a paralytic short somewhere. To locate it, start removing fuses while observing the amperage drawn from the battery with doors closed. If an elevated current reading persists and you’re unable to isolate a specific wiring system, you’ll need to examine the wiring harness wherever you can access it, push and pull on it while observing amperage to try to locate the problem. I’ve had wood rats damage wiring over the years on vehicles, mowers and atvs. Finally,  I passed this on to my Dog, but she wouldn’t even give it a w.a.g. She doesn’t care for  Chevy or Ford Vehicles. However, if it’s a Dodge, you can’t shut her up…..[ATTACH=full]504008[/ATTACH]</blockquote>
