Reply To: Hyosung Aquila GV-125S Starter Switch problems
Have you checked if all the connectors on the bike have water ingress lately?
Also , i could remove the stand switch, inspect the mechanism -> then use contact cleaner to clean the plugs. If the ECU can’t sense it , it won’t start.
Clutch Switch = Same here.
Neutral Switch (under the front sprocket) (don’t pull it out as there is a small spring inside connecting the drum, which is used to track positions , so be wise) and have a bucket as oil will pour our. Top up engine with fresh oil to avoid starving the gearbox. (if 100ml is drained there, then top up 100ml back in)
Ground connections = Black wires or any wires attached to the frame or battery negative.
Starter Switch = Check its PLUG under the fuel tank and open the Starter Switch just to make sure the kill switch contacts are OK. use contact cleaner (loads at halfords)
Starter RELAY Solenoid (Depending on your year GV125-S , it may have “Solenoid Starter + Its own fuse” or just “solenoid” by itself. ) = If these go out, your start button doesn’t work.
