charging battery
 

I discovered my truck (06 F-150 5.4 S cab XLT 4x4) has a dead battery and have hooked it up to my bat charger on 2A autocharge regular. The batt was so dead the key fob wouldn't unlock the door, neither would the pin code on the door. Had to use the key. Also, the headlamps will not turn off while I'm charging it. :confused::hmmm: The Gryphon is VERY dimly flickering while on charge. Should I have disconnected the Gryphon before charging? :help:

It is usually recommended to disconnect the gryphon before doing anything to/with the electrical system. I would disconnect it and charge the battery, then drive the truck around with it disconnected to make sure the battery has a full charge, then once you are sure the battery is good reconnect the gryphon in the correct way. That should solve any flickering, unless the unit got fried... I hope not, and it shouldn't be, but it is possible.
Good luck :)

Disconnect the programmer asap.

Then let it keep charging.

Move your headlight switch from "Auto" (11:00 O'clock) to "Off" (straight up). If that doesn't turn the headlights off, I'd disconnect the negative battery cable. I don't think a 2 Amp charger can keep up with the draw from headlights. And yes, don't leave the Gryphon connected.

Yep, I quickly turned off the charger, disconnected and had batt checked, then replaced with new Autolite batt. That corrected the headlight switch malfunction and then reattached Gryphon, all happy now. :cheesy smile::embarrassed::thumbs up yellow:
