Starter stays engaged with engine running

(1/3) > >>

Mr. Mac:
The starter stays engaged after the engine is running.
The starter button seems to operate correctly. I cleaned it with contact cleaner spray. It depresses and returns fine.
Perhaps the starter relay is the culprit?
Any other ideas?
Thanks much.
Mr. Mac

K2-K6:
Sounds like the relay could cause that, especially if it's had a lowish battery and "stuttered" the relay enough to arc it together. Should be able to continuity meter across the terminals to check it. If ok then meter the supply wires to the relay when ignition is on to see if they stay live.

Mechanically they have a one way clutch on the crank side of the generator. These don't usually cause any problems but you can check it by removing the starter motor then putting your finger in the hole, the gear should spin backward (clockwise looking from left side of bike) really easily but not forward. Motor should be off!! when doing this. The starter is always in contact with the crank gear unlike a car which dis-engages mechanically.

Hope this helps

Mr. Mac:
WD40 lubricant was applied and seems to help. We shall see...

Bryanj:
Have the left side panel off ready and locate the small wire to the solenoid, depress the button and if the starter stays engaged disconnect the small wire---if it stops its the button, if not its the solenoid

Mr. Mac:
Thanks for the feedback, will give it a try.
