I always like to help out when I can. I helped my daddy with these road graders in the sixties. We did most of the maintenance and all the repairs when they seemed to stop functioning properly. There were no safety stops or anything like that on the ones I remember. I can’t imagine how to assist on these. I don’t remember any fuses. A simple ignition switch check would be a starting place. Also battery cable need occasional service. So just enjoy that wonderful peace of history and check it out. Have fun sir

Look in the electrical section of your parts book.

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
