Re: 04 PDS won't power on altrax 4800
Try unplugging, spray cleaning and reconnecting all plugs on the controller.
Measure the voltage between the white and black wire on J4 (labeled as C4 on Alltrax schematics). Ought to be 10V with pedal up and 6V with pedal down.
Errors indicate the voltage is <6V with pedal in either position.
Note: Laptop powers up the XCT via the 5V fed to it by the USB connection. Only the logic circuits are active.
