C145 will not start

[Joshyg 8]

My quad popped the chain so I put it back on, drove my tractor over to jump it and parked the tractor. I went back over an hour later and turned the key and voltage didn’t even show on the ammeter and wouldn’t engage the solenoid or anything.

 A C145 I had  had a fuse buried in the harness between the ammeter and battery. If yours had one it may have blown.

Probably the fuse as Mike suggested. If not, here is a step by step method of finding the faulty part without wasting money on parts you don't need.

Why won’t my starter turn over from the key switch?\

Lets take a logical step by step inspection of your starter problem.

Is your PTO in the ON position, a wheel horse will not start with the PTO on.

Have you had the battery load tested at an auto parts store?

Have you cleaned and tightened all electrical connections including grounds?

Are all fuses good and fuse holders cleaned?

If these have all been done, we can check components of the starting system as follows; don’t skip a step or you may miss the problem.

Be sure the transmission is in neutral and the parking brake is set.

Take a pair of automotive jumper cables and connect the black cable to your battery  "-" and a good clean spot on the engine. Now connect the other cable to the large post on the starter and touch the other end to the battery "+" terminal, does the starter turn over? If the starter turns over the battery and starter are good. If it didn't turn over try the same steps with the battery in your car/truck, if that cures the problem then the "good" battery wasn't so good.

Presuming the starter turned over move the jumper wire from the starter post to the other end of the wire going to the starter which is one of the large posts on the solenoid. If the starter turns over when the battery is touched by the jumper as before then that cable is good, if not you have found your problem.

Presuming the starter turned over move that jumper to the other terminal of the solenoid, connect the other end to the battery and use a small piece of wire to temporarily connect the battery "+" terminal to the small terminal on the solenoid, this should cause the solenoid to close and the starter to turn over. If not, the solenoid is probably the problem.

If this was successful remove the large jumper cable and use the small jumper wire to the small terminal of the solenoid, the solenoid should close and the starter turn over. If not the cable to the battery is the problem.

Presuming all of these have been successful remove the black jumper wire and repeat the small jumper to small terminal, if the starter turns over the ground is good.

If all of these components test good then remove your ignition switch, be sure the transmission is in neutral, parking brake on, clutch depressed and PTO off. Use a small jumper to connect the terminals that were connected to the “B” and “S” terminals of the ignition switch. If the starter turns over then the PTO switch and other safety switches are operating properly and your ignition switch may be bad.

Just happened to my C-125...

When a fuse blows for no explainable reason it is likely that the fuse holder is corroded causing a poor connection, resulting in increased current and overheating.

I'm thinking it blew when he used the tractor to jump start the quad

Working on an old Ford Ranger the fuse kept blowing for the AC fan every time I turned it on. I traced wiring, connectors, everything I could find in the whole circuit that would cause a short and found nothing. I put a fuse in the next size up and it's been working ever since for several years. Once I was working on a '99 Suburban that would not start with a fully charged battery. The starter and all wiring looked good. The battery cable to the starter was severely corroded under the insulation not visible from the outside. Replaced the cable and all was good. Thinking when wiring gets so old the resistance increases which blows fuses more quickly  Maybe the Ranger has minimal corrosion in the wiring causing the factory recommended fuse to blow 

[squonk 46,240]

More resistance lowers the amps so no that will not make a fuse blow. It can cause heat though and cause the fuse to melt
