PEH,
The motor is definitely not wired to the 1.25amp fuse, only the original power wire which is now ONLY use to drive the relay is wired to that fuse. A bosch style relay should require less than an amp. The pump motor is wired through the power side of the relay with a 10amp fuse. I have done some research and found that sometimes when using a device like the ACC to drive a relay it cannot withstand the negative voltage spike created when the relay "unlatches". To combat this I have now installed a 200watt/1amp diode across the ground/switch lugs with the cathode side of the diode to the switch. This will prevent/quench the voltage spike from possibly damaging the ACC. I have also installedupgraded to a 1.5amp slo-blo fuse on the drive/trigger wire from the ACC. Hopefully this will do it. How do you measure current draw from the relay? I have a fairly sophisiticated meter but not a clue how to use it. RT
