Coil switch-diff years+#..look the same

[Scaaty]

Have a 1984 Rude 4HP twin. Losing spark at the bottom plug. Popped the wheel, and it looks great in there, and points look fine. So I want to try a new coil. Now, I have a new coil that I have which goes to a Rude 1955 15hp (still working on it, and it a winter project) that looks EXACTLY the same. Numbers on the top are both 512154. Side numbers are different though. In fact all three have different numbers. <br />One coil on the 4hp are 582993 and 12T-OA<br />Other is 582992 (same), with 3U-OA<br />Rude 15hp coil is 583249 though, with 19L1B-BA<br /> Like I said, they look the same...does anyone know if they are interchangeble. Save me a 50 mile trip to town. Thanks...

From what I find, all 1.5 HP thru 40HP use the same coil, updated # 584477. Should work fine...

Exactly rickdb1boat said.<br /><br />I think they changed the p/n every time they changed what kind of plastic they used on it. Or what colour they painted them. That coil goes by a hundred different numbers.

Didn't think there would be a bunch of different coils, even during all those years. Would NOT make sense to change a simple point ignition design that works. Thanks guys...
