Bolens 750 Husky - ignition question

Britcheflee · Nov 16, 2009

As mentioned in another post I have a Bolens 750 Husky - it has been re-wired to run without starter and battery using a pull rope.
My father in law thinks he knows where the old starter/generator is......my question is, what would have had to be changed out/added/removed to make the tractor run without battery? Does anyone have a diagram of where the starter is located and where the belt would run to - also a wiring diagram would be very useful.
Thank you,

Lee

It never needed a battery to run. The Briggs engine has a flywheel magneto - regardless if pull start or electric start.

If you ever have to change the ignition switch, you have to make sure it's a switch made for flywheel magneto and NOT battery igniton. With a mag switch - ON does nothing and OFF shorts out the magneto. With a battery-switch, ON sends power to the coil and OFF stops the power.

Starter generator needs a battery, voltage regulator, high-amp push button for starting, etc.

Many of the tractors got the electric start added at the dealership. I had to do many (I worked for Bolens dealer in the 60s).

On the diagram you posted can you tell me the location where the black wire which says engine magneto ground terminal goes to (from M side of ignition switch)- I assume the magneto but where is this located on this tractor - this is a briggs and stratton engine 7 hp I belive.

I re-attached everything and used jumper cables to provide power - I cant find the key to the ignition switch - will it work if I short the two posts at the back of the ignition switch? - I have power down to one side of the solenoid (hot side) but it isnt doing anything - may be corroded after sitting for 10 years or more?

Thank you,

All the switch does is short out the magneto to shut the engine off. If you totally unhook all the wires from the ignition switch, the engine will run (if the magneto works). Remember it's got breaker points in it and apt not to work if it's been sitting a long time.

There will be only one wire going to the engine somewhere. That is the shut-off wire. If you ground it, it kills the ignition.
