The other issue that you might check into is bad wiring between the amp and the gauge. This new amp has the self test feature to help eliminate that as a cause of problems.
Here are the pin assignments to the pickup. The numbers are shown on the socket connector on the fender (after you unscrew the cap).
pin 9 is input from sensor
pin 8 is sensor return (gnd)
pin 7 is sensor cable shield
Get a DVM, and put in resistance (ohms) mode. You should get the following readings:
pin 8-9 80 ohms (+/- 20 ohms)
pin 7-9 infinity (open)
pin 7-8 infinity (open)

I was trying to read ohms on the socket today and couldn't get anything from it (engine was running).....I did every combination of pins (including between 8 and 9) and it just said "0.00"....so I guess I can assume the pickup is dead....where the wire goes into it is kinsa loose and icky looking....I'm betting its damaged (or the cable shielding is) I'll order a new one and try that.....and I might still order one of your amp units soon too. If I can get this thing working I will be a happy man!
