Gryphon killing battery

[Jackpine]

I'll add to what Longshot posted. I've determined I have a 0.05 Amp parasitic draw in my truck with it in the "stock" configuration. This is all "keep alive" power for things like the radio, clock, seat position, power door openers, PCM and so on. The monochrome Gryphon pulls an additional 0.05 Amps for its keep alive needs. This is a total of 0.1 Amps, or 2.4 Amps per day. This will kill a fully charged battery in 21 days.

Most batteries are not fully charged. When you shut your truck off, there is a period during which there is a much higher draw on the battery - the interior lights stay on, the headlights may stay on, etc. And, if you open a door or unlock the truck during this "off" time, it creates an additional spike in battery draw for a period.

Your battery may be on its way out - it would be worthwhile to have it load tested.

My truck is a bit of a "Garage Queen", so it lives in my garage with a battery tender plugged in at all times it is parked there. You may want to try a similar solution.
