Wiring a starter button

#1

Post by rocket ron » Sat Jan 11, 2020 7:26 am

I have an RSES starter on my Duo with the button fitted to the frame above the coil. It is connected directly to the solenoid.
As the handlebars are off I’m going to fit the correct starter button as per an Electra.
Checking the wiring diagrams I notice that they didn’t use a relay until 1968.
Question: is a relay really necessary? It would be easier not to fit one.
Thanks. Ron

The relay was added because of switch problems without it. The switch isn't capable of carrying heavy and constant amperage loads and failure was a regular occurrence. (the switch would overheat and melt). The relay stopped that. What you do on your own bike is up to you.

The MoCo was never big on fixing problems, just addressing the symptoms, thus they applied a General Motors horn relay to take the load off of the handlebar button. Later applications called for a FORD starter relay. The later Shovels & Evos use a Bosch, little cubular plastic universal relay. They seem to work well, do not take up much space, and can be mounted most any where since it is not mechanically grounded, but does have a grounding lead wire, a four wire hookup. I use 'em without any problems....

I am running A RSES also. With a heavy duty button wired directly to the solenoid. Yeah if you are going with the handle bar button you will need to run a relay. To much juice for that little switch to handle.
Good to see another running that setup. Don't let anyone tell you that you should not be riding because you are not physically able to kick start any more.

Thanks for all your help but there’s a change of plan. Not wanting to start drilling holes into a nice pair of OEM buckhorns I’ve decided to continue using my existing heavy duty button mounted on frame above the coil.
Of course, if I change my mind in the future I’ll be using a relay as suggested and the NOS starter button that I’ve already bought.

I had trouble kicking because of arthritic knees and now they’ve been fixed I’m not going to chance it. I’ll be ok with the flatheads. Nothing will stop me riding.

First step to fixing problems is admitting they have one! “New & Improved” works without admitting guilt.
