FLtractor 205 #1 Posted 23 hours ago (edited) Afternoon, Took my 856 K181 starter gen off tractor to local shop.. they tested it Said it works good and ran a belt on the pulley.. said will crank tractor long as battery charged. But it is not charging so need new voltage regulator Current regulator has 3 terminals front and underneath wire.. can’t find anything online based on the housing #”s. Also should get new S/G belt. Here is current belt and belt from Napa that supposedly fits. Edited 23 hours ago by FLtractor Share this post Link to post Share on other sites

Thank you for belt #. Interesting the # on Napa is a cogged belt unlike what’s on my tractor now. regarding the Voltage regulator.. do you happen to know of a solar charger i could hook battery to if i decided not to get new voltage regulator?

ri702bill 12,929 #4 Posted 22 hours ago Agreed - you need the raw sided cogged belt. It fits tighter on the S/G pulley and does not slip. Did you attempt to diagnose your old Delco Remy Regulator? They are pretty simple... Share this post Link to post Share on other sites

These files are a lot of knowledge, even with the corny illistrations. Remember that the origin of S/G systems dates back to the 1930's - almost 100 years ago.

adsm08 5,065 #8 Posted 17 hours ago The regulators rarely actually go bad or break, unless they were hooked up wrong, or were exposed to an electrical fault. These are old designs, from the days when things were meant to be worked on. They can be cleaned and adjusted and brought back to life as they wear. If you remove the top cover and hold the unit right-side up with the three posts facing you the set of contacts responsible for charging will be to your right. Cleaning them with some fine sand paper and making sure all the other connections are good an clean, and the wires are in good shape, is likely all that is needed. There is a website where high-quality regulators can be purchased still. Of course I can never remember what it is. @ebinmaine Eric, is it you that always has to remind me of that site?
