Unplug the the pressure sender. If the light goes off then its a bad sender. If it stays on then the wire is shorted to ground somewhere.

I don't think I'll buy another Autometer mechanical boost gauge again. I had a phantom series that was inaccurate, yours reads wrong, and I know of 2 other people here who have inaccurate Am gauges.

I like the autometer electrical sending units - never had any issues with them

Just to add in about autometer boost gauges being horrible. I went through several autometer boost gauges with my srt-4 and none of them were accurate at all including the stock one. They were fine in the box but once hooked up they would end up reading 3-5 psi low with the car off. Good luck and hope you get that resolved.

First fillup - 35.8 mpg. 306.7mi on 8.576 gal. Adding 3% to the odometer mileage to account for the extra .7in of tire diameter of the 155r12 over 145's.
