Hey wondering if anyone can help me out, good friend of mine has the Hitachi EX 120-3, 1995 or 1996, burned out a resistor on the PVC unit. It's R1 and I cannot find a schematic anywhere. Downloaded two different shop manuals and neither of them show any electronics. I ohmed it out and one day it was 700 ohms and the next it's 300. He lives in Montana and I live in Ohio, don't want to take a chance and mail it all the way out there with the wrong one installed. The resistor is discolored so I cannot tell by the bands what the value is.
