LaVern Posted January 18 Report Share Posted January 18 (edited) Hello All, Its been almost 2 months since I last posted about the 1977 TY250D 493 series that trying I am restoring for my son. Well in the process of replacing the points and condenser I managed to scrape the source coil pretty bad. Apparently the tool to keep the flywheel from turning stuck through too much at one point. I'll post some pictures. Looking at all options I think rewinding the coil would be the most cost effective. But to do that I need the resistance specs on the coil. I have a service manual but it is the European version and it doesn't have any info on an American version. Anyway, the specs I have give 2 different required resistance, one for 9 European countries and that spec is 1.6 ohms. and the specs for the English model is 0.1 ohms. Can anybody give me the specs for a 493 series sold for America? I already have the points and condenser purchased so I should probably try to use the magneto ignition vs. a CDI though the CDI seems to be less maintenance and more reliable. Thanks.
