Where's the ground? Losing battery volts.
Our 2002 7.3 Excursion is a month old to us and when it sits for over 3 days, it's a bear to start; sluggish turnover.
Last week I started comparing this truck to our other Excursion with a voltmeter and found that the batteries are fine, and they hold a charge when disconnected. connect them back up and the volts start to drop like rocks.
First question would be to find the ground strap and make sure everything is tight. With my bad back, I'd rather have an idea of how to get to it the first time, so any help locating it would be appreciated.
Second is that this new truck had a lot of extra electronics added to it. How can I test to learn whether the volts are leaking through an appliance instead of from a bad ground?
