Bill,could you explain this some more? I don't see how a ground can
short to to
ground?
Next we pulled the brushes from
the stator, here we found more wire insulation melting on the Negative
side
of the brush assembly. The rubber gasket was warn away and the wire
connection to the negative side had touched the engine case causing a
short
in the system. Uncle Bill!
Shorted brush circuit!
Re: Shorted brush circuit!
Riceburner and the rest including Harry, that gave me some feedback on the
shorting issue. Your right, I was not clear.
Let me explain; The brushes have two leads one marked White with red
stripe, the other black. The White with red stripe shorted to the engine
case along with the black wire causing the black wire to heat up and
actually smoke a bit.
Harry was right, while we were trying to figure why the black (Ground) wire
was over heating, there was less resistance on the wire than the ground
cable from the frame to the engine. And, something I didn't think about (but
Harry did), this could be happening more than we may have thought. I have
had (on several occasions) the black wire (ground) which comes from the
brush assembly straight into the voltage regulator melt the voltage
regulator connector. This circuit is on the battery side of the 45 amp body
fuse so there is no protection, so when the white with red stripe wire
shorts to the case, it causes the wire harness to melt together, taking out
the voltage regulator along with it.
