I bought a 518H without a coil and need some help with the wiring, a the coil was not there when i bought it and I have no idea how to wire up the coil I bought.\r\n\r\nI have a black wire from the condenser\r\nI have a larger gauge yellow wire that I would guess is from the switch.\r\nI have a black wire and I have an orange wire both encased in a white sheath that go down lower on the engine. I think these go to the ignition module.\r\n\r\nThe engine ha the foil model tag on the top of the engine, but it is not readable as it is faded badly.\r\n\r\nAny help hooking these wires up would be greatly appreciated.

Go to the Toro manual site and download the Demystification Guide.\r\n\r\nHere is a link https://lookup3.toro.com/request/request.cfm\r\n\r\n Just enter 41-20OE01 in the model number that's for a 520 but the manual has all the wiring diagrams.\r\n\r\nIf the wiring hasn't been changed the holes in the terminals are different sizes. The coil terminals are two different sizes one is smaller than the other, so obviously you have to put the small wire end on the small terminal.
