Dylan poucher 7 #1 Posted May 1, 2023 So I have a c-175 8speed I was driving it around after it sat for a while and after I got over a hill my lawnmower died and when I turn the key on, off, and start I don’t have anything I don’t have power any where I have checked the grounds and they are ok the motor is a pressurized engine I would like to be able to cut grass but I can’t since I don’t have any power anywhere from it I have replaced all fuses as well does anyone know what to do to help it start again? 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,510 #2 Posted May 1, 2023 Have an ammeter in the dash that monitors the charging system? See if you have battery voltage at both terminals. If not the ammeter has failed. Disconnect the negative battery cable. Remove one of the wires from the ammeter and add it to the other post. This takes the gauge out of the system and makes a safe connection. Reconnect the negative battery cable. 3 Share this post Link to post Share on other sites
Dylan poucher 7 #3 Posted May 1, 2023 Attach one wire from the ammeter to the other one? I’m not completely understanding that 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,510 #4 Posted May 1, 2023 Most ammeters have two studs on the back with a wire to each stud. Put both wires on one stud. Does not matter which one. You are just joining the two wires together. 2 Share this post Link to post Share on other sites

It don’t make sense to me how that could work and my amp meter did work Share this post Link to post Share on other sites

Placing both wires on the same post eliminates the meter from the circuit. If it starts, you know the meter is the issue. Then you can decide on a permanent solution.

Ok .So your mower died. I assume that you took the blades out of gear before trying to start it up? Easy to forget and commonly happens when you run out of gas or stall under load. 2 2 Share this post Link to post Share on other sites

gwest_ca-(File Mod) 11,510 #10 Posted May 1, 2023 This may not be the correct year but click on the fuzzy picture and it will go to a page you can enlarge the diagram. You can follow the wire from the battery + to the ammeter. Power goes through the ammeter and back out to power the rest of the tractor. We are guessing the shunt between the ammeter terminals has failed. Connecting the ammeter wires together will bypass a failed shunt. 1 1 Share this post Link to post Share on other sites

I would also take the time to clean and tighten all battery cables and take a look to see if mice have had lunch there. 1 Share this post Link to post Share on other sites
peter lena 9,298 #12 Posted May 1, 2023 @Dylan poucher go over plug in relay points , move wire connections , any corrosion ? simple basic function check , have any alligator clip test wires ? to insure connection ? had a recent horse I sold that was loaded with those areas put a small TYE WRAP on related spot , then went back and eliminated ,and verified function . what I do , pete Share this post Link to post Share on other sites

953 nut 60,220 #21 Posted May 2, 2023 Here is a step by step guide to find the problem without replacing perfectly good parts. 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 1 1 Share this post Link to post Share on other sites
