ignition key

[Kevippolito 3]

why isn’t power getting to my ignition terminal of my key, it’s a brand new key switch. when i turn the key the engine cranks over, but i have no power going to the coil? any help

Does the new switch have an "I" terminal on it ? I would be for Ignition

If it's designed for a magneto ignition it is grounding that terminal you have going to the coil. and would have a M on the terminal. The switch should have ID letters on the back next to the terminals

What are you even working on?

oh man! it does have a M on it, i just thought M standed for motor! it’s the 5 pin key setup with the wiring harness, so i thought it would’ve worked, is there anything i can do to fix it or is the key junk? they key also has a ground terminal that i have running to ground. by the way the tractor is a 1973 no name 12 hp @wallfish

Wrong switch. You need a battery ignition switch with an I on it.

You didn't hurt anything. Get a switch intended for battery ignition

A- Accesories (lights and such)

R-Regulator/rectifier

I- Ignition (to the + side of the coil)

B-Battery ( wire from the + hot side of the solenoid)

S- Start (small post on the solenoid )

 

Had it been the other way around with battery ignition switch on a magneto engine with 12v supplied to a magneto coil -- it would let the magic smoke out of the coil. No harm on yours and a valuable lesson with something learned. (Switches are not all the same and different applications require different switches)

A 103-990 switch should get you back in business. This diagram may be helpful.
