Re: Chassis Battery Problem

A better way is to make the test connection before disconnecting the negative cable. 3 or 4 hands might be needed unless you have alligator type clips or similar.

How is it done, how is the test connection done before disconnecting the negative cable?

Make before break is the idea.

A switch is often used: http://www.mastertechmag.com/pdf/2009/J ... cdrain.pdf
from the article:

It absolutely has to be a “make-before-break” transfer to avoid sending one or more modules back into an initialization process.

You'll see it done other than “make-before-break” all over the internet but I think “make-before-break” is the better way with today's highly computerized vehicles. A clamp on ammeter makes it easy.

I just don't know about using a test light for this - it won't tell you the amount of the draw.

Was your RT plugged into grid power when the chassis battery went dead?

Took my Chevy/RoadTrek to the area Chevrolet Dealership, McGee Chevrolet in Raynham, MA today. They checked it out, worked on it for a good 3 hours, checked everything out.

Testing the battery it failed test, shorted, battery had to be replaced and was replaced with a 800 CCA battery, the original battery was 600 CCA.

They also did a free 32 multi point inspection on the vehicle.

I questioned the mechanic reason for the 800 CCA battery, and not being replaced with the same type as the original, his answer to myself and the service consultant was that the dealership was told to do so.

Seeing that I have less then 36,000 miles, (30,066 miles), less then 3 years, will be 3 years February 4, 2013 the battery was replaced at no charge, no charge for labor.

The replacement battery is a 78PG - 78-7YR, AC Delco Professional Series Battery, understand it has a 42 month Free Replacement warranty.

Will now see what happens.

If the problem returns this week Ron then you would have to suspect the Battery Separator. Everything Chevy related has been tested.

Hi Mark,

That is what I figured it could be the Battery Separator if the problem returns this week.
