Lightning Bolt Warning Light Problem - Redux

called hoye's today. they told me to check the fuse. they said the replacement regulator that i put in several years ago should have not failed. the fuse is not getting good connection. now i got to find the fuse panel. i think it is some where under the dash behind the panel in front of the gear shift.

I mentioned that in post #5. Your fuse panel is right under the dash, little to the left of center.

fuses are good. battery is good. took it out and had it checked, showed 12.65 volts. that is good with me running the tractor and 30 plus starts trying to run this problems down. load test was also good on battery. checked all wiring, all were good. but i still get 12.4 reading on the red wire, yellow wire and tan wire coming from the vr-522 six wire voltage regulator (vr). on the starter i have a wire from the battery and a red/white wire and a red wire going to the same post. i have read you take the red wire off to check the vr. but the red/white wire and the red wire are made on the same spade. looks like a factory job. when i take the red/white/red wires off the tractor and put the battery wire back on the starter the tractor will not turn over/start. i have a wire that goes to the top of the start at the solenoid that has no power to it when running. t i can not see what color it is, except yanmar green. so it looks like the second vr has failed or i am missing something. where do i look now before i buy a third vr.

When I bought my YM2000 I was having the same exact problem. It has both Regulator's also Old style and New. Drove me nuts. Ended up loose/bad were it connects to the back of the Fuse Panel. After finding it and curious I hooked the Old Reg. back up and it works also.

I don't want to be a naysayer but I have replaced my vr522 regulator twice on my 2002d. In my earlier post I stated you should get 13+dc volts out of the red and white wires coming out of your regulator. I think instead of white the wire is probably yellow. In any event if you stick your red test probe down in that plug to touch the wires it is the red one and the one right next to it. Naturally you would have your black test probe touching ground. Just to clarify I am posting a picture. I remove myself from all liability if you buy a new one and it doesn't solve your problem. I just know from personal experience these so called "no problem" regulators can go bad. I also know mine puts out 13+ volts on those two wires. :thumbsup:

Yep! it was the the yellow wire 10 amp. connection on the fuse panel. And sure enough CRS. so I had to go look. Were does it go? The Voltage Reg. I have a 520 Reg. yours should be a 522 but it looks to be wired the same looking at my YM2000 Dia.

Yep a "no fail" part can fail. After all its just a part, they wear out.

I have replaced many "no/low failure" parts on all kinds of things in my day.

Exhaust manifold in a southern truck at 20 years old, stator in one of my outboards, lets see on and on... THose are just a few that come to my mind. There are plenty of others im sure.

Oh last work truck i had, new power steering pump at 30 000 miles, catalytic converters at like 60 000miles......

the red, yellow, and tan wires read the same, 12.4 volts. so it looks like i will have to replace the vr for the third time.

Got in a new voltage regulator and on it went. Problem gone. It looks like the voltage regulator was the problem all along. But i did all the checks and run down all the wires to make sure I did not have any other problems. So now the tractor is on it's third voltage regulator. I just hope this will be the last one I will have to do.
