September 14, 2025Sep 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
September 14, 2025Sep 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.
September 15, 2025Sep 15 @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, 2025Sep 16 by Tr1AL
September 16, 2025Sep 16 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, 2025Sep 16 by faussy

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 ?
