Motorcycle Questions? Ask a Mechanic.
Hi Johnny, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.Initially, proposed preliminary try (if have not been done) would be to check, clean and lubricate/exercise the side stand switch. In some instances, it may be necessary to bypass the side stand switch even if just for test purposes.
If not corrective, all others would require the use of a multi-meter to check the wiring and potentially including the diodes.
