I installed the new rectifier and the fuse did not blow. So I guess it was a bad rectifier. But with 12V across the fuse box, won't my battery drain over time?
EDIT: I mowed successfully.
I've taken some readings.
Old rectifier:
- Center pin to housing, about 28 ohms. One side pin has no continuity to housing while the other has also about 28 ohms.
New rectifier:
- Center pin to housing, about 41 ohms. One side pin has no continuity to housing while the other has also about 41...
None of the three inputs to the voltage regulator is shorted to the engine block, even at X1K ohms. I tested this by removing the regulator and sticking one prong into each exposed port while the other was touching the block. Is one of these the stator wires?
The mower does not blow the 20A fuse if the regulator is unscrewed from the engine block (even if wires are still attached).
Which are the stator wires? Should neither of the other two non-fuse-wires leading into the voltage regulator be shorted to ground?

My Cub Cadet SLT 1550 is blowing the 20A fuse as soon as it is inserted, even with key off and ignition switch unplugged from the back. It reads 12v DC at all times across the fuse box.
The red/white striped wire that leads from the fuse box to the DC alternator has continuity to the frame of...
