Safety Switch

Still can't this girl to crank. Using a bump starter I connected one end to the batt post on the solenoid and the other to the yellow/red wire coming from the "S" terminal on the ignition. With bump starter engaged I don't get anything to either of the lower posts on the solenoid and I am suspect of the safety switch but I am unsure if I understand which switch it is speaking of. Underneath the flywheel is where it appears the lead coming off the 2nd small post of the solenoid leads I'm assuming to be ground if the switch is in the correct position....is this correct? Or is it speaking of the neutral switch inside the remote which the first small post of the solenoid runs through? If it's the switch under the flywheel can I just bypass this switch by connected directly to ground? Cheers.

Re: Safety Switch

I would bypass that once and see if that works. You basically have to pick things apart to see where the problem lies.

There are two wires on the small solenoid posts. One comes from the ignition switch, and the other goes to the safety switch. Indeed, the safety switch is under the flywheel and is actuated by the timer base when the throttle is moved.

Yes, ground the safety switch wire and see if it cranks. Those switches are so often burned up by somebody jumping 12V to it while attempting to jump start.

Bottom line: The ignition switch sends 12V to one small solenoid terminal, and the other small terminal is grounded through the safety switch at slow throttle settings, ungrounded at high throttle settings (which prevents cranking at high throttle and running over somebody). Don't defeat it permanently unless you have great liability insurance and an even better lawyer. And an uncaring concience.

That's exactly what I needed to know! Thanks all for taking the time to reply it's appreciated.
