Spindle analog voltage low

Post by dlewis69 »

I have been having trouble with my Acorn board, specifically the spindle voltage out. I am getting around 1.2v out with the spindle stopped. When running spindle bench test I get like 1.4v on stage 1, if I enter 1.5 it is right on for the remaining stages. Voltages are read right at the terminal on board. Admittedly I have let the smoke out of a couple of boards already but having learned why (and paid my lesson fees) I haven't on this one. Anyone else experienced this or have any ideas? Report and pics of my setup attached. Thanks in advance.
