Strange fuel pump issue

Basically, it sounds like you took the pump relay out of the circuit.....  What does "well ground" mean, exactly??  I've been working as an electronic calibration and repair technician for close to 30 years, and have NEVER heard that term before.............

FYI, I did not have time to investigate further. I had a leaking fork and had to swap it from spare bike as leg was scored. Am off for a trip up north so everything is on hold until Sept 23rd. :bye2:

The 3 wires going to original tach is what I used, grey for signal to tach, black for ground and brown for positive. All wiring has been checked for open or short. I re-installed the stock gauges to check if I can be back to normal but no, I am still missing power from the igniter after startup. Is there a schematic available for the 92 igniter internals?

 :dash2: :dash2: :dash2: Problem solved after reading the 'reserve switch' thread. Yup it was my reserve switch shutting down the fuel pump. :yahoo:
