VF750F 1983

Gents
I've acquired this VF750 that has sat for around 9 years and am having some
small problems with it. Firstly I spent many nights dissembling and cleaning
the carbs and then reassembling them AAAHHHH!!... Not for the faint hearted.
only to find the coils were open circuit. So second hand coils and.....fuel
pump not pumping?? Bypass pump relay and away we go yes it started after
some time and all seemed to be well until I felt the rectifier and found it
to be somewhat Bl@@dy hot. The wires running to it were wrapped in elect
tape which had started to melt. I've removed the tape and found three yellow
wires. My problem is, are they wired correctly? and if not which one goes
where? what is the reason for the wires to get so hot? Are they supposed to
be all yellow. I've checked the voltage at the battery and it is charging
over 14volts....normal??

Thanks
Rod

3 yellow wires from alternator to RR. It doesn't matter which wire
goes to which of the three pins on the RR for those wires.

If the wires are getting hot, there's too much resistance. I'd start
by checking the connector where the alternator hooks into the main
wiring harness, and then the connector at the RR. An easy solution
(well, it eliminates the wires as a potential problem, you might have
other issues as well, such as a bad RR) would be to get yourself 3
lengths of larger-gauge wire, cut out the connector at the
alternator, and solder the heavier wire on there. Run that wire to
the RR and attach it to the RR (solder or spade terminals as you
prefer. Solder, if done properly, is more secure and less prone to
corrosion, but a PITA to get on and off.
