My just bought a used 7518 with a lift and the speed wanders on the 1 setting and all other settings go to max speed.
Ive blown and cleaned but no fix. The card is $130.
Ive read that replacing electrolytic caps will fix it but that must be for another model because the caps look inaccessible.
And Ive read suggestions to use the Harbor Freight Speed Controller vs repair I guess becuase it cant be repaired.
Could it possibly be caused by worn carbon blocks?
Anyway your insights repair it.
Thanks!
