The 550 isn't showing that it is charging the battery. I've noticed its been sluggish starting.
I tested DC at the battery, 11.35 when not running, 11.35 when running.
I'm looking through the shop manual at the diagnostic tests to narrow it down. And check all connections.
When i took the engine out i had to cut the alternator wires, but i reconnected them with crimp connectors and shrink tube... maybe its corroded.

The Intimidator is made in Arkansas and the company was affiliated with the Bad Boy products at one time. The engine is a Kohler 750. I replaced the flywheel and stator a year ago, so I feel like they are okay. The battery was replaced and all the cables are good, no corrosion.
The wiring diagram shows a rectifier/regulator and an inline fuse that the manual said could be my charging problem. My questions are:
1. Are these rectifier/regulators some generic or, are they specific to each machine?
2. Are there UTV parts companies that handle parts for all brands of buggies?
3. If the answer to #2 is yes, could someone recommend the names of parts companies I could contact?
Earlier this year my battery was weak and I had to boost my mule to start it then I decided to remove the battery to check the fluid level which was very low, I set the levels and recharged the battery a few months later it did the same thing, so I had to boost it again then checked the voltage running was getting around 16 vdc ( which is too high) and fluid level was very low again and wouldn't hold a charge. Note: The battery was maybe 1-1/2 years old. Then I replaced the battery and checked the voltage running nothing changed I was only reading battery voltage it wouldn't increase with increased engine speed. I changed the voltage regulator with an aftermarket one, same thing not charging. I checked the alternator per the service manual which states .3 ohms or less it checks at .2 ohms and not shorted to ground. With the engine running I disconnected the alternator and it had around 22 vac idling and around 60 vac revving the engine, so I figured the regulator was bad so I replaced it with another new one (aftermarket) from a different company, again not charging only reading battery voltage. I did put the original voltage regulator on nothing changed still not charging. Using the manual wiring diagram did continuity checks going to the voltage regulator everything checks out OK. Now what am I missing?
I recently bought a used Kubota RTV900 with a plow attachment to take care of a long, steep driveway this winter. I think it’s a 2006 and it has about 460 hours on it. The previous owner told me when I bought it that it needed an oil change but I know nothing else about how well it was maintained over the years. While going through the items in the maintenance schedule I discovered a problem with the coolant system. The coolant reserve tank was completely empty so I filled it and soon after noticed a spot of antifreeze on my garage floor. I had never noticed a leak before. I took the protective panel under the radiator off the bottom of the RTV and could see that the radiator itself, the drain valve, and all hoses and connections were dry and tight as far as the hose going into the engine block. I then took off the next protective panel that is right under the forward part of the engine. The engine-facing side of this plate was covered with a mess of oily debris that had to be scraped off and the engine itself was pretty dirty also. I cleaned things up with some paper towels and ran the engine to see if I could spot any leaks. After running the engine for only a few minutes, I saw a drop of coolant on the side of the crankcase right behind the starter motor. I wiped it dry, started the engine again, and the drop re-appeared after a few minutes. I was expecting to find that maybe the water pump was leaking, but I don’t see how that would cause the coolant to appear so far back on the side of the engine block. I can’t see anything else that might spray coolant onto this area. If the cylinder block actually has a hole in it I would expect I would see a lot more problems than just a slow leak of coolant. I am fairly handy but as I’m sure you can tell I’m new to engine work so I thought I’d see if anyone could help me diagnose this problem. Thanks.
