I did get a speed pickup mounted and have been doing some threading, seems to work just fine although I am using an older version. .034 or something like that.
Also just finished installing a VFD, my Harbor Freight motor died, bad starting cap. I had more trouble troubleshooting it to the cap than it took me to swap to a 3phase motor and vfd.
I went through the relay starter with a fine tooth comb until I discovered the leaking cap, had that thing apart 6 times before the light came on. Half the wires in the relay start/reverse were poorly connected, half loose, the relays were designed for larger wire and would not crimp down tight on the small guage wire they used. That lead me down the path to thinking loose wiring.
