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?
Well, after a bad experience with repairs to our Trooper, Lloyd tore into the engine himself. We originally wanted to save time by hiring the engine rebuild out, but that bit us square in the butt. Remember the discussion about Silverbullet motorsports in Yuma??
Stay tuned....we'll let you know what happens.
Has anyone rebuilt the engine in these troopers?
Does anybody know if a kawasaki FD440V engine will interchange with an FD620D? It looks like the same engine from the outside but has an internal governer which you would not need to connect and a different crank output side so maybe you could swap cranks or have the FD440V splined at a machine shop. It is 15HP instead of 20 HP which isn't great but is probably plenty of power for most applications, so I am assuming it has a different bore size but you can pick them up for cheap. I don't need an engine now but would like to have a spare on the shelf. The FD440V is used in John Deere rider mowers model LX178.
Here is an example of one on Ebay with decent pics:
