Re: HFS3 problem
slight update. had a look at the relay and the pump wiring. with ignition on:
the blue and red wires going into the relay are both +12.xxV the thick red wire from battery is +12.xxV and the wire going to pump is 0V.
looking at the manual i thought the blue is -ve and should be 0V when i check with multimeter with other wire on ground.
