gauges peg out

[jlarsen]

i have a friend that has a 2002 F150 and lately every time she goes to start it her gauges peg out like when the computer is reseting. what could cause this? thanks

I would start by checking the batteries and connections otherwise I have no idea

My first thought aswell. maybe a ground issue?

Is the radio clock and other memory items restting like radio presets and trip computer and compass if equipped?

Sounds like Batt is giving up the fight.

sure its not just a general test? i know some gm vehicles do that for self checks. did the gasser had a pcm flash recently?

I haven't been able to tear into it yet. Its cold rainy and dark here.

She needs a new battery, I am 100 sure of this, mine used to do that when the battery was low all the time but I was too lazy to replace it.

I learned something. The Lightning had been doing this lately but cranking fine. Guess I solved it when she got the newer battery from the diesel.
