Not a sound when pressing start
Posted: Fri Jul 26, 2019 1:34 pm
My project bike started just fine a while ago. I did some final installations of the seat, gastank etc. For some reason, now when i press the "start" button, nothing happens. No sound. Not even a click from the starter relay.
At first i thought that its a faulty starter relay / solenoid, since when i jumped it, the bike cranked just fine. I replace the solenoid and it still didn't work. I also now checked both the solenoids resistances and they were in the specs (4,7 ohms).
Now i pointed my attention towards either:
- oil level
- sidestand (i don't have this connected at all, and it worked like that before, so i guess that should be fine like that)
- neutral switch
- killswitch (tested this from the relay and and should work just fine)
I wasn't completely sure if the oil level sensor and neutral switch should close the circuit when they work normally. So could i easily test them against the ground with just the multimeter beeper mode? I already tested the neutral switches resistance (following the instruction manual) and it seemed to work just fine, and since the bike started earlier just fine i doubt that the oil level sensor would have gone bad in between. I did wiggle and work on the exhaust, so technically it could have done something to the oil level sensor but i doubt it.
I now have a feeling that the starter relay third wire (so the signal wire, white and blue) could be somehow acting up. Is there some instructions on how many volts i should get between that and ground when not pushing and pushing the start button?
Does anyone have any good tips on where to look next? I'm running out of ideas
