It grounds to one of its own mounting bolts. Then replaced the VR with the newer
model VR (2003+)(I had to drill 2 new bolt holes in the bracket and put in two
longer bolts as the newer model VR is thicker than the 2000 model. Plugged it
all back together. NO FUSE BLEW. Started it and it ran like a charm.
Learned also that the red/white wire ties into the VR circuit somewhere
not shown on the electrical wiring diagram. Something to be aware of.
Now, the battery is charging at about 13.5-14 volts.
Note: since I could not locate recommended replacement 20A 250V fuses, so I used 20A 32V
auto fuses ($2 for 4 at Radio Shack and at Autozone). This should be ok as this fuse should
blow with even lower resistance than the 250V fuse.
