I have a 97 f-150, last winter I installed an alarm system in it. I followed the directions to a tee; when I hooked the power wire to the positive terminal on the battery all my gauges on my instrument panel spike upwards fully. Now when I am driving my fuel gauge floats up and down, my temp gauge goes all the way up over the red and my oil pressure gauge falls all the way to low and they just stay there, the battery gauge floats between 12 an 17volts. I talked to two different ford dealers in my area, One said it's probably a weak battery and the other said condinsation my have built up behind the instrument panel causing some sort of short. both dealers said they have never heard tell of this before, so I'm reluctent to beleive them cause I think there just guessing like I am at this point. " well maybe it's this or maybe it's that" So just wondering if any of you may have any solutions or any guess as to what my problem may be. Thanks!

 

Sometimes a bad ground can cause funky electrical problems like that. Make sure your alarm brain has a solid ground. You may try grounding it somwhere else temporarily just to test it.

 

ground it in the left kick panel, but by itself. Don't tap the the ground in with the factory grounds. I install alarms and remote starts for a living and the best place to ground them is in the drivers kick. good luck

 

OK, I'll try moving the ground and see what happens. Thanks!

 

I Moved the ground to left side kick panel. Didn't seem to make any difference oh well back to the ole drawing board. thanks anyways.
