battery drain?

[RGSMDNR]

Could the programmer be drawing current while the truck is turned off? I had a dead battery the other day and cant figure out what could be causing the draw.

thx

Correct me if I am wrong, but once you turn the vehicle off or remove the key, the gryphon is not pulling anypower, unless you turn to the on position.

Yes it does pull current with the truck off. I can't find the thread around here right now that talks about it but I remember "Jack" had measured the current it draws and its in a thread around here somewhere.

And, that thread is accurate for my truck. I have not had a single problem since using the battery tender whenever the truck is sitting in my garage.

Interestingly, I always find I have to run the battery tender (max charging current 1.25 A) about 8-10 hours after driving the truck to bring the battery to a full charge. And, my alternator supplies around 13.9-14.1 Volts when I'm driving. So, even after a full day of driving, the battery seems to be (according to the way the "tender" works, at about an 80% charge level.

I cannot explain this, and it doesn't make any sense to me. It's just the way things are.

Jack, I bet that the numbers your getting have something to do with the Voltage=Amps/Resistance formula. If the battery tender uses clamps to connect to the battery then it will read more resistance than the vehicle(because the vehicle has been bolted in since day 1). More resistance is going to make the voltage look lower without any higher amps. Could be wrong but it sounded good when it ran through my head.
