Have a Model 88 (Gas) circa 1950's. Need electrical wiring diagrams that provide enough detail on the push starter, ignition/light switch, ammeter, coil and generator. The page I have from the Operator's Manual is not detailed enough. Would a appreciate a faxed copy (just let m eknow if someone has one).. Any tractor regardless of the brand built between about 1957 and 1965 or so would have had a 12v generator. Any Oliver diesel and I assume other brand diesels built anytime before 65 or so would too. Any tractor parts supplier including YT should have 12v generators and the saddle type regulators that bolt on top like the original 6v on that 77.
