Turf Tiger problem...electrical

BRIGGS model 613177...when I engaged PTO mid afternoon clutch didn't engage. Loaded up and when I went to start to unload nothing. Checked infamous fuse blown. Still won't start with boster but did startwhen I jumped from tiger cub. I now assume voltage regulator but waiting battery to get charged so I can measure voltage. Is Iit same as kohler 22 ac on white wires and 13 dc on red?

Ok the ac from stator is 17.3v ac. I took the regulator out one of the female connectors on ac was burned. Bad connection. Formed the connector and cleaned and loaded with diaelectric tune up grease. After connecting plug I had 12.73v at battery. This might get me along until I can put parallel wires on that ac.

Driving like hell over bumpy terrain might cause this? Or getting water in it? By the way dust was over about 10% of the cooling fins on regulator.

How long will a fully charged battery last after regulator fails while mowing.

Ed,

Was those voltage readings at idle or 3/4 to wide open speed ?

Burnt connectors are usually caused from moisture (water) causing rust/corrosion then a less than adequate connection.

A fully charged battery run'n a electric PTO will last in the neighborhood of 35/45 minutes before the PTO will shut off from lack of power, The engine however will continue to run for a while until you shut it down. But..... It may not start after doing so.....

That ain't enough AC volts. Depending on yer alternator, it should be putting out a MINIMUM of 20 VAC (for some)to 30 VAC (for others) @ 3600 rpm or so. The output needs to be checked at full throttle.

Should be around 13~14.5 DC at the reg. output/charging wire.
You can always bypass the connector/s and butt splice or solder the alt. to reg. wires,no?

Thanks....at full throttle with pto on I read 13.6volts dc so I
Think I am okay. It took almost 24hrs to charge that battery so it was really dead.

Thanks I am going get rid of that connector and replace the one remaing fuse holder that continues to cause problem. And I am going to peak at the amp gage once in a while.
