Phan 15 #1 Posted Saturday at 03:34 PM Hello, I am about to clear snow. The C160 cranked and fired (briefly 5 seconds), and then were no any clicks. Battery rates 12.6v. Light test (ignition on) - no light to the ignition or the solenoid. Please give me advice. Thanks you! Share this post Link to post Share on other sites
953 nut 55,828 #2 Posted Saturday at 03:40 PM Sounds like it is time to do a little deferred maintenance. Clean and tighten ALL electrical connections including grounds. 3 Share this post Link to post Share on other sites
ri702bill 8,507 #3 Posted Saturday at 03:42 PM Several things to check, as mentioned above. Is the PTO disengaged? Seat and clutch switches working as required?? 1 Share this post Link to post Share on other sites

Clean and tighten ALL electrical connections including grounds. yeah the battery ground and solenoid ground are the big two here. I wire brush or sand to bare metal and a little dielectric grease for them. 1 Share this post Link to post Share on other sites
squonk 41,351 #5 Posted Saturday at 04:23 PM Careful. Dielectric grease is an insulator. It does not improve conductivity. Use it to protect a connection from outside elements only. 1 Share this post Link to post Share on other sites
Phan 15 #6 Posted Saturday at 04:36 PM Thanks to all! Just an undate - I retested the lights (photo attached). The terminal light clip was attached to the solenoid (picture) and touched to the following as these orders: 1) the other side of solenoid, light yes 2) the coil, light yes, 3) the starter, light yes, 4) the + terminal battery, light no (but I noticed a small fire) I also notcied that I had been a weak/brief an electicshok when I touched to the tractor - why? I was scared about this. Please help! Regading cleanning and tightening the eclectical connections / grounds, I will follow through. For the PTO, it was disengaged. I have no seat swicth (it has been disconnected since I had it). As for the clutch switch, I am not sure, but mine is an C160 H. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,100 #7 Posted Saturday at 06:20 PM Somewhere on the transmission controls there will be a switch that closes when the transmission is in the neutral position allowing the starter to operate. This neural switch along with the pto switch in the pto off position completes the circuit for the starter. The small wire at the solenoid gets power and a clunk when the electro magnet closes on the large solenoid terminals - power to starter motor. When testing with a light connect the clip on the wire to a known good ground - battery (-) is good. Then probe with the tester to check for power. Share this post Link to post Share on other sites
Roger R 448 #8 Posted Saturday at 06:46 PM (edited) ...."I also notcied that I had been a weak/brief an electicshok when I touched to the tractor".....Likely static generated by your coat or other fabric(Nylon jackets are notorious for this) and if you are wearing boots, with rubber or other non conductive soles they will prevent an ongoing static discharge, and the tractor framework makes a sufficient ground for discharge. Nothing to worry about except if there is a concentration of gasoline fumes present at the point of discharge. Not a likely situation, but something to be aware of.

squonk 41,351 #9 Posted Saturday at 06:57 PM Clutch switch on a C 160 is on the frame of the tractor right next to the clutch brake pedal. There is a ball in the switch that the base of the pedal is supposed to push in when you press the pedal. On many of these the ball is stuck from rust and the switch is disconnected. The wires are tied together so the start circuit will work Share this post Link to post Share on other sites

Phan 15 #13 Posted Saturday at 10:28 PM By far, I checked all wires, they were tightened. I also replaced the wire between the terminal + battery and the solenoid. I sprayed an electrical spray bought at an auto store on each connector. However, there is still no clicks. Tomorrow, I will go though again. I do remember that a "no click" issue had happened to my B100 before, that time I found a broken PTO switch. 1 Share this post Link to post Share on other sites

Did smoke come from the battery cable, or the battery itself. If smoke or fire came from the battery itself you could be in danger of a battery explosion.

There was no smoke coming from the battery, you brought up the good point; I will pay attention on it. Share this post Link to post Share on other sites
Phan 15 #16 Posted Sunday at 06:38 PM Hello - an update. I follow him posted on Youtube. Here I found out: Step-1: Check battery, I got 12.5 v Step-2: Use a light test for the following: a) + battery to the solenoid pole + battery, light YES b) – battery to the solenoid pole starter, light NO c) – battery to the solenoid pole + battery, light YES d) – battery to the solenoid pole red wire key switch, light NO, when turning the key on, light NO Step-3: Jumper wire bypass from the solenoid pole red wire key switch by touching at + battery, crank YES (when the key switch is the OFF position). This is to verify that the battery, stater, and solenoid are good. Note-1: Using a small wire did not crank. Note-2: It would not start because the key is the off position and the system is ground, but rather to verity purpose. However, I am not sure waht is the next step I should do. I checked the safety switch at the brake pedal, NO any rusts and free moving. I checked the PTO interlock, NO rusts and free moving. How I know that the key swicht is ok?
