Charliedimmock46 Posted September 14 Report Share Posted September 14 Hi all, I’ve just picked up a ty80 to restore for my daughter when she’s old enough. unfortunately the engine casing has cracked which has caused oil to get to the stator and the ignition source coil is now giving continuity to ground. im struggling to find a replacement specifically for the ty80. Does anyone know of any other which fits? It’s a single coil stator 1 Quote Link to comment Share on other sites More sharing options...
kurtas Posted September 14 Report Share Posted September 14 Get it rewound by a place that does small coils. Quote Link to comment Share on other sites More sharing options...
konrad Posted September 14 Report Share Posted September 14 I'm not saying your coil is good, but oil won't cause it to short out. Lots of large transformers are cooled by being immersed in oil. Everything is in parallel with the source coil. 1 Quote Link to comment Share on other sites More sharing options...
Old Gezzer Posted September 15 Report Share Posted September 15 HI, Many years ago I fit a Stator form a small DT Yamaha. Worked a treat. 1 Quote Link to comment Share on other sites More sharing options...
Tr1AL Posted September 15 Report Share Posted September 15 (edited) @Charliedimmock46 DT50/DT80MX 1982 looks almost identical but has lighting coil included. take that off if you do not want it . Go to ebay to find one second hand , not cheap though. Regards Alan.. Edited September 16 by Tr1AL Quote Link to comment Share on other sites More sharing options...
faussy Posted September 16 Report Share Posted September 16 (edited) Were the points open when you measured this continuity to ground? Open the points, and then also try removing the condenser, it can short to ground if faulty. You can get a new condenser at most autopart stores or online for a few quid Edited September 16 by faussy 1 Quote Link to comment Share on other sites More sharing options...

Yes, points open/points closed, it wouldn't work if it didn't. I have to make a few assumptions.... Are you sure you know how a magneto works ? Where are you showing this continuity ? And are you using an ohmeter ? 1 Quote Link to comment Share on other sites More sharing options...
