C175 Won't Turn Over

[Thisguy68 2]

Hey all. 👋🏻

 

I have a C175 Wheel Horse tractor. I use it to plow and as a back up mower. I had some trouble with the starter solenoid and it would just click. I could feel the click when touching the unit. I installed a new one, but now it won't even click. I checked the PTO several times to make sure it wasn't engaged. I checked to make sure it's getting 12V from the battery and that checked out. Also verified there is power at the starter. Could it be a faulty new solenoid? Or wiring issue? I included some pics. I would think a faulty starter would at least show some sign of life and not go the same time as the solenoid. Happy for any help/suggestions. Thank you.

 

 

Also I forgot to mention I replaced the points and condenser at the same time. I attached the wire from the coil and condenser to the points, maybe that's wrong? I will update with a picture when I get home.

The solenoid body needs to be grounded.

I grounded the solenoid to the body and was hoping that's all it was. The solenoid DID start clicking again, but the starter is still not engaging or spinning. 

     Then, I tried to jumpstart it because the battery had been sitting and only measured at 12.2V. Unfortunately, that just made the starter smoke. I found a diagram here, but the wiring looks correct to me. Thanks for the help and responses

Is there a possibility that the starter is jammed?

It could be, anything is possible. I can manually spin the spring loaded gear to engage the flywheel but the starter shaft won't spin and just smokes. I'm guessing I should remove the starter. Should I be able to turn the shaft by hand? Do I need to remove the engine? I've read a couple different threads, but they weren't specific for this model. Looks like it's just two retaining nuts and the wire on the back. Thank you for the replies.

I would take the starter off and hook up 12 volts to it and see what it does. If it spins and engages then the starter is good if not I would get a new starter. Also see if you can spin the engine over by hand. It it doesn’t budge then you have a bigger problem.

Just hook the positive battery terminal to the starter post? Do I need to ground the body? I'd probably use a set of jumper cables and car battery so I just want to make sure. Gonna see if I can get it out tonight if I have enough daylight or tomorrow afternoon. Thanks again.

Update: I pulled the starter and figured I'd open it up since I'll likely replace it anyway. Smells burnt and looks awful. I'm an amateur as far as electronics but I don't think the copper from the windings is supposed to embed in the arbitrage.

Since it does look like that I would get a new one. I don’t think it’s supposed to look like that.

I was able to take the starter off my parts tractor (another C-175) and cleaned it up. It spun freely and I installed it. The starter engages and the engine started when priming the carb. Tractor dies when fuel in the carb burns off. I am not getting fuel flow so I'm looking at replacing the fuel pump and considering upgrading to an electrical setup. Oddly, the starter won't disengage sometimes, even when I turn the key off. Feel free to chime in on these new issues, I just wanted to update the post in case someone has a similar issue. Thanks again to the forum and it's members.

I have a C-175 that the fuel pump wasn't working. I think at the time I read something about the cam lobe that drives it wears(?)

Went with one of the $12 pumps at least 5 or 6 years ago. Still working great, it's my main mower

I put everything back together today and the tractor would turn over, but not start. I checked the points timing again and made a main fuel adjustment on the carb. 

 

I turned the engine over with the points cover off to see of there was spark and it started right up. I reattached the cover and it won't start. I can only tighten the cover screws about halfway or it dies. I'm guessing the top screw (or the metal tab it attaches to) that holds the coil/condenser wires is somehow grounding out? I searched the forum, but haven't found anything besides point adjustment. Has anyone heard of thos issue?

Sounds like you have properly diagnosed the problem. Make up a new wire from the points to coil or find the frayed spot in the insulation and give it several wraps of electrical tape and you should be golden.

New one for me!

@953 nut has you covered.
