Hi All,
When switched on the bike doesn't prime the fuel pump and says fail on dash. The power relay (38 on diagram) has 12v going in but minimal voltage out - sometimes. I was able to get it to show 12v out to the G/R wire that feeds the pump, the dash also showed the normal sel1 instead of fail, after unplugging everything on G/R circuit and then reassembling. Both switch wires also had 12v. The bike started and idled until I reved it and it died. I think the vibration of the rev made the issue return. I was not able to get it to prime after that. I followed power from the battery to the power relay, so the starter relay and power fuses are good. When I omit the relay with a jump wire it spins the pump and the bike runs. When I jump the switch the G/R wire still only gets minimal power, so I don't think its a switch issue.
Sounds like a bad relay right? Well I have 3 on the bike and when I swap them around all have the exact same G/R wire voltage. I even bought a cheap one on amazon b/c it was available next day. It shows the exact same voltage output. Could there be something going on with the G/R circuit that is causing this? I can't find continuity with ground on the g/r wire. When I jump the relay I have 12v throughout the G/R circuit.
Do I have 4 bad relays? Thanks
