Recently the Grizzly 1001 has exhibited a slowing down to almost a dead stop.
Grizzly and SB techs both say "loose belts."
Took the belt department on the machine completely apart and cleaned, adjusted and re-started and it slows down all by itself. The motor pulley slows down, too, so it's not slippage.
Decided to get into the electronics and look for loose connections, cold solder joints, out-of-spec measurements.
Found a questionable speed potentiometer and replaced it with an Allen-Bradley pot from an 800T speed control.
Am now on the way to reassembly, and I notice the schematic diagram is way different in several places than the way the machine was assembled, e.g., color codes are different, and the way things hook together do not match.
Please advise. If I blow it up it is being hauled to Recycling because both Grizzly and SB both say many parts are discontinued because of COVID-19.
Thank you for your commentary.
