C-120 not charging

Recommended Posts

608KEB

The battery is not charging on my 75 C-120. I changed the regulator and cleaned the connections. The ampere meter is showing no charge. I have this multitester, but have no idea how to use it. Could someone walk me through how to test the electrical system,. Key switch, regulator, Stator and Battery?

First thing to do is to hook the leads up to the meter and check the battery with the engine stopped. You should have a little over 12 volts DC if the battery is good. With the engine running at near full speed, you should be getting a reading of about 13.5 to 14 volts.

 

Let us know what you find, then we will take the next step.

Do I unhook the battery terminals? Is this the correct setting on the multimeter?

I put the MM on V 20 and the battery reads 12.77. So the battery is good. What's next?

I think I found the problem. I'm not sure if the stator works. My multitester 9v battery went dead. Could someone tell me what to set my multitester to. for checking if the stator is charging. I also accidently touched the 2 stator wires together and it sparked. I'm guessing the stator must be working.

Glad you found the problem. FYI, to use the multimeter to check amps the leads need to be connected in series with the circuit. It looks like that meter is 10 amps max so you could damage it depending on what the charge rate is. Checking voltages as Bob M mentioned will be fine.

28.5 VAC coming from the stator at 1/2 throttle. I soldered and heat shrunk tubed the new connections. Tractor is charging like it should! Thanks guys!!

      Hello gentleman, 
       
      Problem: will not crank on its own, will crank with jump box—but still not fire
       
      Recent things I did prior to this issue: cleaned fuel filter, replaced battery cables, replaced cable from ignition to starter
       
      I have my test light out and am probing around. 
       
      There is no power at ignition/magneto wire or the ignition/starter wire
       
      There is power everywhere else

      Need some help. My 800 Special has an electric PTO. It is not working. Checked Ohms - nothing. My questions are 1) how does the PTO come off and 2) can they be rebuilt? I took the bolt out that I thought holds it on but no luck. Must be something more?

      hello all I'm a new owner of a 312-8 tractor, have starting problems, came across a very small, what I believe is a relay between the battery and the dash,its about 2/3rd size of a cube of sugar silver on the outside blue on top with a hole bout the size of a pea, theres 6 pins with wires connected to it on the bottom do not know what this is any thoughts? I cannot determine the exact year of this machine for there is no tag anywhere only tag on engine kohler magnum md #m12s   ser# 170370459  spec#  471527  I figure its mid to late 80s to early 90s. of all the wiring diagrams ive looked at it does not show any thing like what I just described also can that little circuit board be removed that's like a test point for idiot lights? any help would be appreciated  jeff
