pdubray 14 #1 Posted April 19, 2020 Battery is not charging, checked the rectifier and the 3 prong terminal is disconnected, easy fix hook it up won't start. Unhook it starts right up and runs. Any ideas on why? 1 Share this post Link to post Share on other sites

pdubray 14 #4 Posted April 19, 2020 The connector plastic has a hole in it. Share this post Link to post Share on other sites

953 nut 59,297 #6 Posted April 19, 2020 I presume this is a new acquisition and the previous owner failed to mention that. Has the wiring had some non-factory alterations? If there is a significant amount of corrosion on some of the electrical connectors and the rectifier is shorted out the voltage drop across the bad connections could add up. 1 Share this post Link to post Share on other sites
pdubray 14 #7 Posted April 19, 2020 (edited) Yes a new tractor, and not sure about new wiring. Will look into that. Put a meter on battery running full throttle and was getting 12 volts. Will also be cleaning the connectors as well. Thank you Edited April 19, 2020 by pdubray 1 Share this post Link to post Share on other sites
peter lena 9,190 #8 Posted April 19, 2020 pdubray, connections are a regular issue, you could try using a dielectric grease at every connection point after lightly sanding contact areas , insures connectivity and stops corrosion. by the way i recently replaced all 3 of my regulators on tractors . all of them being more then 20 plus years old , on line at about 12 $ each . no more issues . pete 1 Share this post Link to post Share on other sites

The small engine shroud mounted ones or the large older style? Share this post Link to post Share on other sites
peter lena 9,190 #10 Posted April 19, 2020 ZTX, i used the smaller shroud mount, regulator , i have 3 magnum 12 engines , and replaced all 3 .i was having erratic charge rates, now they are all solid with no fluctuation, pete Share this post Link to post Share on other sites

pdubray 14 #12 Posted April 20, 2020 Thank y'all for the suggestions, they were very helpful. Yesterday I cleaned and tightened all electrical connections and happy to say the old horse is charging like she should be. Share this post Link to post Share on other sites
