Need new voltage regulator.. S/G Belt

[FLtractor 205]

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.

Kohler 7hp, 8hp                                                      Kohler # 231605                                     3L-32   Notched raw rubber edges NAPA 25-7315

 

A fabric covered belt like that will not grip enough to start your engine.

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?

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...

Ha - that's funny. No - the info I have goes waaaay back. 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.

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?

Not me. I can't remember it, and I can't remember who normally, and I am still dealing with some after-effects of that head shot I took last Friday.
