1985/86 VF1100C and 1984/85 VF1100S turn signal flasher replacement:

The V65 Sabres and Magnas with self-canceling turn signals use the same flasher as those on non self-canceling SabMags, but they're wired differently.  The turn signal flasher relay has 3 terminals.  One goes to power, one to the turn signal switch, and one to ground.  On SabMags with self-canceling signals, the 'ground' terminal goes to a circuit inside the instrument cluster's cancel unit that grounds this lead.  When you press the left or right signal switch, it sends a momentary pulse to the cancel unit, which grounds the blue/black wire going to the turn signal flasher relay until canceled.

If your ex$pensive Honda turn signal relay (38301-MF8-771, 38301-MF8-773, or 38301-MG9-681) fails, it can be inexpensively replaced with a few commonly available auto-parts store components:

Any 2-terminal automotive flasher made for 2 bulbs will work on most SabMags, but on ones with self-canceling signals you'll also need a standard single-pole, single-throw or double-throw relay and socket.  The relay only carries the current of 2 bulbs, so it needs only about 5 amps capacity.  Most Bosch automotive relays are at least this amperage, but I'd use a smaller relay to save space.  Soldering may be required.

Below is a diagram showing how to connect the relay and flasher to work with an 85/86 V65 Magna or 84/85 V65 Sabre

Disclaimer:  Although this diagram is electrically correct and should work, I have not (yet) performed this fix on anyone's bike.  At SME-Bob 2003, Jim Swomley's V65 Magna flasher relay was found to be hanging down below the inner fender and had been damaged by water and dirt entry.  We replaced the relay with a simple 2-prong cage flasher wired between the green/yellow and gray wires and the flashers worked, but would not auto-cancel.

Investigation of the signals appearing on a known-good bike (Malcolm Lorente's V65 Magna) showed the blue/black wire to be grounded by the cancel unit when the signals were selected, then released from ground when the cancel unit or center-push button turned them off.  Logically, this circuit should work, but there's always the danger of releasing the special imported Japanese smoke from expen$ive parts of your bike.  Be careful!!!
