Tecumseh voltage regulator problem

11 years ago

The voltage regulator of this Tecumseh 7HP engine is not working. (VH70 135008) The voltage at the battery with the engine running is 12.2 VDC. The battery is in good condition and fully charged.

In the picture below you'll see the red wires coming from the stator on the left side. The voltage from each wire to the left side of the diode is 15.6VAC.

On the right side, the battery voltage of 12.2VDC is measured at each end of the fuse and on the right side of each diode.


I don't have any manuals to troubleshoot this condition and would appreciate any advice of what to do next.
