I just bought a Cub 147, which runs ok, but it doesnot charge, and the gauge shows Discharge while running which is not good. I tried replacing the voltage regulator, since one of the rubber flex mounting brackets was broken of the old one. Polarized it, and still no charge. I then took a meter to the generator, and got 2.80 volts off the generator. I pulled it apart, and found some worn brushes. Could this be my issue, i dont see why its discharging though, however the wiring has seen better days, and could be rewired, what can i do to fix my 147? Thanks!!

Did you look up a wiring diagram? A rebuild for the s/g is probably in order. It cost me about 75 dollars 8 or 9 years ago.

When I got my 129 I had the s/g rebuilt and then bought a new regulator. Then had to repair some wiring that was rubbed through and then the gauge switched sides.

Good luck.

With it running, hook a meter to the battery, take a jumper wire conect it to the positive battery post, and momentarily touch it to the F terminal on the S/G. It should go to full charge, if it doesn't then the S/G is bad.
