So if I were to bridge from the yellow red wire which shows a voltage drop when the starter button is pressed, to the low side of the relay pull in coil, effectively bypassing the ecu, would my starter button then work?, or might it cause problems with the ecu?. I would disconnect the low voltage wire to the relay and replace it with the bridging wire from the switch
Check the voltage of Yellow wire on Ignition Relay #3 on diagram, I think it's the only solid Yellow wire on the relays. You should have close to 12V. I believe this is the wire Wayne tied a good 12V from a main fuse or from your batt w/fuse wire for StartusInteruptus. Hotwire to solenoid doesn't hurt anything unless you push button while running.
Again, remove the plastic starter and make sure you can't move the ground connector. How do I know? I went through everything you are describing including a new battery before finding the loose ground.
Hi Roy,Thanks for your input.Yes, the status interrupts was done a long time ago, 12v to the relay at all times, and 12v to both the pull in coil wires too, relay changed and then renewed, no joy, and there was continuity from pin 1 on the ECU to the relay. I replaced the ECU, after cleaning many times, including the earth, and I rigged an auxiliary earth from the body of the eco to the battery neg, when hot wired from the switch bypassing the eco it worked fine
