Went through another project and now back on this. I did find an open 12K resistor on the regulator board which I replaced. I have also installed a new regulator transistor. I have just over 10 volts on the supply, but only 2.5 volts to the motor. With or without the motor connected. Way to low. When I connect the motor the supply drops to about 5 volts, but I still have 2.5 volts on the output. Output should be 3.64 volts. I checked the capacitor in the motor and it is not leaky. I didn't think it would be. I suppose next I will finish checking resistors. The error amp transistors check ok, as does the bias diode. I may replace them anyway.
