Gryphon acting weird....

[Jackpine]

I'll add to this. It sounds like a weak battery to me too. Try to have your battery load tested - it can be done free at most automotive stores. I think the Gryphon is very sensitive to low battery voltage at power-on. In many ways, I see this as a good thing, an early indication of impending battery failure.

One other thing you can do is check the no-load resting voltage on the battery after any "surface charge" has worn off and the vehicle's electronics have all gone to sleep. After driving the truck, open the hood and then wait about three hours. Without opening any doors, check the voltage at the battery terminals with a multimeter. Anything less than 12.6V is an indication of a weak battery.

Thanks Bill and Jack for your quick response.....I'll keep an eye on the battery and see if that proves to be the problem. Checked it this morning after sitting all nite and it read 13 volts on the nose. I know that's getting close so maybe the battery is the villain. Everything is working fine so far today and had it out the heat for a while....

P.S. By the way Bill, I misspoke....I have an EVO that has been upgraded to a Gryphon....should it come to that does it still qualify for an RMA# ?

We can still RMA it, it's just not under warranty. If something need to be replaced there would just be parts costs.

I'm getting confused now. 13V is high for a "resting" battery. Can you confirm this was a voltage meter reading (not one from the Gryphon) that was taken across the battery terminals with the engine off? Normally, a fully charged new battery will read 12.7V in this state.

I am having the same problem as mentioned above. My gryphon is approaching two years old and it is a 05 SuperCab. But it has started intermittently with a blank screen, I thought it was the Texas heat because it did it a few times last summer, and now it has started it again. I am going to have the battery checked as recommended and see if that fixes it.
