cst-280 problems
cst-280 LK070056G flashes blue 4 times and red led on pc13 8 times. Tried another cr1 relay and still nothing. with machine on i had 14 volts on my coil wires to boost relay. Any tips or suggestions on diagnosis or repair on this machine? My next guess would be a bad pc13 but I'm not sure how to properly troubleshoot it. Thanks
