Reviving an old thread. I meant to do this long ago, just never got around to it.
My solution is not nearly as elegant as Forchetto's or Alex's. I'm too lazy to find something suitable as a permanent plunger, so I went with Mr. tri-umph's idea: a golf tee. The golf tee will be fastened to the relay with electrical tape, and the tape will also cover the hole.
I imagine any sort of poker could be used: a pen, a tooth pick, a nearby twig. Anything!
This relay looks just like the universal ones found at the local auto parts store for a few bucks. Good to know if it ever fails. And if that is the case and I become stranded, I can just rip out the relay I use for the heated grips, right? I also assume that the chances of this type of relay failing are slim and none.
Thanks, once again, to the RAT forum for all the great mods!
