Just removed, cleaned and reassembled the bakelite disk with the snow shoe contacts and cleaned the corresponding rivets on Heat Wave 's thermometer advance unit. (Didn't remove the square board with the rivets from the unit.)
After the reinstall, the same problems had not been fixed, and there were new problems.
On the off chance that the disk was not on tightly enough, I gave the nut another half turn.
That fixed the new problems (mostly) and I still have the original problems.
My next step, mainly because I can't think of anything else to do, was going to be taking it all apart again, and checking the wiring behind the rivets. But,
If a half turn of the wrench was what it took to get some of the connections working again, does that indicate its time for new snow shoes? They are spring loaded... seems like the unit would allow for a little give in the system. I'm afraid to tighten it any more... but maybe that would fix all my woes.
How do I know if I need new snow shoes?
