Joe Sullivan 18 #1 Posted January 24, 2022 Hey all, I’ve got a wheel horse c165 that is not charging, I’ve had issues in the past with this tractor not charging. Which was resolved by swapping out the voltage regulator, I tried that again this time, and this time that is not the problem. Where would you guys start? Thanks!

oldlineman 1,450 #2 Posted January 24, 2022 Make very sure that the voltage regulator is grounded very well even to the point of running a separate ground wire to the outside of the regulator. Bob 3 Share this post Link to post Share on other sites

Bob Thanks for the reply. Regulator is grounded very well, and I’ve made sure of a very clean connection. 2 Share this post Link to post Share on other sites
Achto 26,501 #4 Posted January 25, 2022 1 hour ago, Joe Sullivan said: Where would you guys start? I always start at the stator. With a multi-meter set to AC power, plug the leads into the 2 stator wire (outside or top 2 terminals on the regulator plug) Start the tractor and rev it up to 3/4 to full speed. You should have between 30 and 40 volts AC. If you do not, check for broken wires. If wiring looks good then I would suspect a bad charging stator. If your AC voltage is good, then you are back to a regulator issue. 3 Share this post Link to post Share on other sites
953 nut 51,512 #5 Posted January 25, 2022 If what Dan @Achto suggested isn't your problem (30 to 40 volts AC from stator) you might want to look at the wiring from the ignition switch to the R/R. The rectifier/regulator has to have 12 volts from the battery applied to the output terminal to work. Could be a connection is corroded or needs to be tightened. 2 1 Share this post Link to post Share on other sites
peter lena 8,035 #6 Posted January 25, 2022 @Joe Sullivan , I use small alligator clipped wiring to hunt out wiring issues , try this , regulator ground / mounting bolts , clip on and go to battery ground cable bolt , behind dash , also just a light swipe of dielectric grease on the plug on connection . worth a try , pete Share this post Link to post Share on other sites
rmaynard 14,864 #7 Posted January 25, 2022 (edited) I would first take my multimeter set to DC and check the voltage at the battery with the engine running at mid-speed. Charging voltage must be checked with a battery attached. The voltage should be between 13.5 to 14.5 volts. If not, I would suspect 1. Connections, 2. Ammeter, 3. Fuse, 4. Regulator.

grinchsr 593 #8 Posted January 25, 2022 I am having the same problem so I am following. Can the ammeter be bypassed ? 1 Share this post Link to post Share on other sites

grinchsr 593 #11 Posted January 25, 2022 Thanks for the replies. Will try the wiring bypass Share this post Link to post Share on other sites

Joe Sullivan 18 #14 Posted January 28, 2022 Thank you all for the awesome support! My issue has been resolved, turns out, I simply had a faulty ignition switch, replaced the switch, now I’m charging great! 1 Share this post Link to post Share on other sites
