New to the forum! Got a question about the shaker voltage.
I have a problem with the resistor burning out on the high current driver board. Checked voltage, and it's around 50VDC.
I'm also reading about 50VDC from the aux power board post-rectifier, but only about 30VAC pre-rectifier (realizing that this is the 25VDC circuit). Aux board has an unpopulated power resistor R10 whose value is not specified in the schematic. In the schematics, I see a varistor which I believe is supposed to limit the DC to around 47v.
Any clues at to what's going on? There's not much in the circuit, so not a lot of suspects. Varistor maybe?
Thanks!
