Tail Section Modification
Part 3: Flasher Upgrade
As mentioned in "Honda 919 Tail Section Modification Part 2: Turn Signal Integration" integrating the turn signal into the rear tail light causes the turn signal to flash faster than stock when the brakes are applied. I've ridden my 919 like this for some time, but decided to go ahead and upgrade the flasher to slow the turn signal back down. I did this more out of boredom due to the weather turning cold and not being able to ride the 919 much, but now that it's done I like it better. It's a very cheap and simple upgrade so if you're not happy with the turn signal flash speed after integration this is a simple solution.
The parts you will need are a Tridon Stant EL12 Heavy Duty Flasher or the like, some 14-16ga waterproof terminal connectors (male and female), a couple of zip ties, about a foot of 14ga wire, and a small metal clip of some type. The wire will be used to make the stock wiring a tad longer and the zip ties and metal clip will be for mounting the HD flasher back to the bike in the stock location using the metal clip.
The stock flasher is under the seat on the right hand side. It is the last block in the rear of the relay pack. It will have "FE246BH" printed on the flasher. It is attached to the motorcycle via a rubber grommet. Just pull up and the flasher will pop loose. Unplug the stock wiring and clip the connector off. On the stock flasher the GRAY wire will go to the side marked "L" and the WHITE wire with GREEN stripe will go to the side marked "B". You may want to note this in the event you want to change the flasher back to stock at a later time.
Once you've cut the stock connector off the wires, attach a male terminal connector to each wire. The terminal connectors I use are waterproof. They employ a heat shrink design to assure water tightness. After splicing them in simply heat the covering with a match or lighter until it shrinks around the wire. Make two jumper wires about 5" long with a male connector on one end and a female on the other. These will be used to lengthen the stock wiring to allow the HD flasher to mount in the stock location.
Attach the jumper wires to the stock wiring. I recommend using two different colors to keep track of which wire is which. I chose yellow and black. Once the jumper wires are put in I taped the wires up with electrical tape to protect the wiring.
The HD flasher has markings by the connectors to let you know which wire goes to which connector. The stock WHITE with GREEN stripe wire should go to the connector on the HD flasher marked with an "X". The GRAY wire should go to the connector marked with the number "1". Finally, attach a metal clip of some type to the HD flasher using two zip ties. The metal I used was an "L" bracket that I bent to more of a "V". This is optional but allows you to attach the HD flasher back to the bike in it's stock location using the stock rubber grommet.
Finally, turn the key on and test the turn signals. They should now flash at the same rate whether the brake are applied or not. Thanks to the "Honda919Rider" from the Honda Hornet Yahoo Message board for turning me on to this flasher.
