I have a 1996 Series C 753. Recently, I am having issues with the aux hyd. circuit blowing fuses intermittently. I have read about the Pulse Width modulator but am not real excited about paying $600 on a whim. I have checked the wired coming down out of the right stick under the cab for possible bare spot. I plow snow with this machine in the winter and this issue happened a couple times this past winter.....then didn't rear its head again until recently. I was using the auger and had drilled over 100 holes this season so far....then POOF. I don't know much about this thing, but am looking for guidance here if anyone has suggestions. Thanks for your help!
