No Screen

My father in law borrowed the truck and when I got it back there was no power to the unit. I have tried to unplug it and replug it. Its been a few months now and I'm afraid I might have screwed up by waiting to get around to this because I might be out of warranty now. Thats what I'd get for having a busy life and also being a procrastinator. I originally thought it was just a simple thing I could figure out and fix, but now after reading some other posts I'm worried it might have gotten fried somehow.

Any ideas?

My first thought is that possibly the OBDII port is not receiving power. Does your cigarette lighter work? If not, you probably have a blown fuse - replace it. The same fuse powers the cigarette lighter and OBDII port.

If that was the problem, you'll need to plug in the unit with the ignition key ON (engine off) to let it boot properly.

The outlet closet to the driver is out. Are you telling me that is all the problem is...that would be awesome, I will go check right now!

Yep! That is one of the most common things as to why a Gryphon won't even power on. I blew that fuse the other day, and had the same problem, but I knew it right away as I always have something plugged into that outlet. I've started using a 25a fuse in that outlet as I have blown it several times will very little load on it using the standard 20a. But upgrade the fuse at your own risk.

If you are really worried about upgrading the fuse you should upgrade the wires between the fuse and wherever it leads to... that way you can have the bigger current draw without worrying about the wire burning up. , just my 2 cents

You got me there Tico...I'm still considering upgrading to an F650 lower dash panel so that may be something I do if I go that route.

I would keep the original fuse size in there. Not just to save the wiring in the dash but also for the programmer. It is some rather sensitive equipment. If you are constantly blowing fuses then there is something you need to look at. If you are drawing too much from the socket then wire up another one. I have a total of four in my console. Three are on top that are made to run simple, low draw things like my GPS, chargers, etc. I've got another one underneath that is wired for about 25 amps but for now it just runs my CB radio. I use the actual cigarette lighter for keeping my MP3 player charged. I prefer to use my own wiring because just my console is able to handle over 60 amps. I decided to make it able to handle 6 100 watt lights and some smaller accessories...if I needed it to.
