I have a montgomery ward hydrostatic 14, model GIL 330480. The wiring is all sorts of messed up. The parts look original. the ignition switch might not be. Its a four post ladeled BSDC.
I need to know how all components should be wired up. From switch to lights to foot pedel and all .

:wave: Welcome to the forum! What engine is in this tractor? We have a wiring manual for the B&S twin cylinders. Not sure what others may be close to your tractor.

 

EDIT: the ones with wiring diagrams in our Manuals section are 5 prong, labeled BGSLM

The manuals section doesnt have one and im new to this site so the many forum categories are a little overwhelming.

Im not sure what engine is in it i just recently started to work on it. All i know based on placks and stickers is its a montgomery wards hydrostatic 14 with model number GIL330480.
It has one spark plug so one cylinder. The wireing i need to know is from the starter ignition switch to the head lights, to the PTO light, to PTO lever switch, brake pedel switch, starter solenoid, voltage regulator, battery, hydraulics, starter motor, amp guage, headlights switch, PTO switch, and anything else i might have not mentioned.

The switch u mentioned has M on it as in magneto. My tractor has a 12v battery with a voltage regulator so magneto probably isnt needed?

The magneto is what fires the plug. The M on the switch grounds the Magneto to kill the engine. This may help you some. It may not be the exact model as yours, but most wiring is very similar.

I would have thought the Gilson Owners would have visited here last night.

i thought Magnetos only fire the spark plug when a fly wheel is present. My tractor does not have a flywheel, if i get the switch anyway how do i wire it?

Believe me, there is a flywheel in there. As far as wiring, check the link I posted above for a diagram.

Why would the tractor need a fly wheel if it has a 12v battery an alternator and a voltage regulator to charge the battery? Just trying to learn

The flywheel helps to balance the crankshaft. ALL engines have one. Plus the stator is in behind the flywheel and uses the magnets inside to make it charge!

Humm ok, most the work ive done has been on small engines with pull strings that need flywheels to survive and start. So the magneto on a switch, does a wire even go to it? Normally the magneto wire would go to a little white box near the flywheel on a small pull string engine. The diagram you posted doesn't appear to have a wire attached to the magneto post. What use is it then?

Does your tractor have a starter/generator or is it direct start with a small gear drive starter?  Your tractor has self contained magneto ignition, it does not specifically need a battery to run, only for starting and lights.  The flywheel and mag are inside the shroud.  My tractors are direct start, and the wiring gets tricky because the direct start engine has a two leg alternator.  One lower amp leg is rectified and only charges the battery, the other leg is unrectified and only runs lights when the engine is running.  Yes, it runs the lights on AC voltage when running, they run on DC with engine off.  Your tractor will have a three position light switch if it is direct start.  If it has a starter/generator, the tractor is 12V DC all the time.  Confused yet?

So heres what i did. I replaced all wiring on tractor, replaced starter solenoid, replaced ignition switch, replaced fuse and fuse holder, replaced the spring that touches the PTO lever, replaced the spring that touches the brake pedal rod, replaced the battery, and replaced the battery cables. Starts up and purrs like a kitten! Thank you all for helping me get this beast set straight :)
I think the main issue was the ignition switch and bad wiring. Cheers
