so I took out the test light and started searching for the missing link  . cleaned the key switch with contact cleaner and got power everywhere but the run mode  and the wire to the safety switch  . well I decided to get cute and jump a wire in the ignition reached for my light and saw smoke come from under the engine cover :flamethrower:

so I fried the mag right ? I was so close. it was turning over .not to fast , not to slow

what would be a proper way to get power in the run position or am I missing something ? safety switch maybe ? thank you

 

simplicity 3415H unreadable model number

engine number 325431-0126-01

it does not have coil ......yet lol

How do you fry a mag? The only way I can figure that, is, if it is the wrong ignition switch. A switch for a magneto should ground to shut off and do nothing when running.  A switch putting out power would be a switch for a coil system. Check that before going any further. Good Luck, Rick

Rick. this might be the answer to your question. 

 

." well I decided to get cute and jump a wire in the ignition reached for my light and saw smoke come from under the engine cover" :flamethrower:

 

If he jumpered voltage into the mag, I'd say he fried it if its electronic.

DougT you are probably right. I missed the importance of that statement. I plead distraction. I had a tooth pulled yesterday. He should do a full diagnosis with an ohm meter with the battery disconnected. Good Luck, Rick

If you touched a hot wire to the "M" terminal on the ignition switch you will definitely Burn up the mag. The m terminal is only supposed to be grounded with the switch off and should never have power on it.

If one of the terminals on your switch is marked "I" them you have the wrong switch for a magneto ignition. These switches look a lot alike and will plug into the wiring harness interchangeably but with devastating results.

Switch on left is for magneto ignition while the one on right is for a battery powered ignition.

it was bound to happen I have had to much good luck . so for now I will hook up a coil using phils beautiful wiring diagram and see if the engine runs before I yank it out to put a new mag on it :beer:

Alec, I added more info above after you posted.

Over a period of thirty to 50 years a lot can Change on these tractors. My favorite tractor started life with a magneto powered engine with a starter generator, then I converted to battery ignition. Changing the wiring and ignition switch. Then I repowered with another Briggs but with a geared starter and stator charging, eliminating the mechanical regulator and totally rewiring, changing switch back to magneto ignition.

Btw I would not bother cleaning ignition switches as they are available for $10-12 at most auto parts stores. Or you can pay $25-30 from your local simplicity dealer for the same Sten switch.

you should just send me that nice clean switch and a new mag . mine looks like the one one the right COSMETICALLY but I will find out tomorrow which one it is .kinda strange they would let it plug in like that bein that every thing is different .

yea I have power on the start part of the ignition and power coming out to the safety switch ( switches ) but no pwer at the switches .  so I took a break from my back and was fine tuning the carb and started feelinhg burning speckles on my face . :mad2:  thought it was gas spray and then I see water leaking out the tractor and Im like WHAT THE HELL???? this thing dont have water ??? my belt had rubbed a hole in the battery ! and it was sprayin me with acid so I washed my face and moved on to the loader ( and the bucket wont come off but thats another story )
