Strange...

[TravisBickle]

I decided to update the look of my Fazer by replacing the stock incandescent filament bulb indicators with the stock LED ones from the MT-10.

Got the indicators delivered from Fowlers and the wiring looked strange at the outset. Not just two wires coming from the unit and terminating in a plug, there's a bit that spurs off on the live wire with two inline 2.2 ohm resistors making the delivered voltage 6 volts.

Tried powering it with and without the resistors. Without doesn't seem to be any brighter but has a very deep rich orange colour whereas running on 6 volts is more yellow in colour.

Anyone else come across this before? I know LEDs don't natively run at 12 (or 14.4) volts so there's gonna be a votage drop somewhere, just seems strange to me to have it inline in the wiring loom rather than being built into the units themselves...?

Also worth noting I ran the flashers for a few minutes with the resistors being bypassed and have used one of them bypassed to get to work and back (so running at 14.4 volts) which is 30 minutes each way and that unit hasn't burned out yet...

Yet.

An LED is, first and foremost, a diode. A forward biased diode acts as a dead short, and a reverse biased diode acts as an open circuit. Perhaps the circuit wires are small enough to create sufficient resistance in your circuit, or maybe the flasher unit does. Bottom line, there must be something in your circuit to limit current through those diodes. If not, the diode will fail in dramatic (explosive) fashion. I know this from experience.

True I just wondered if maybe the wiring on the MT-10 differs from FZ1 which would cause it to need a voltage drop, and whether I should be bypassing the resistors on my FZ1 or not because of the wiring being different...

Parallel resistors are there to provide the correct resistance so an analog relay flashes at the correct rate because a diode on it's own has in essence infinate resistance and so if you have an analog relay they'll flash too fast.

For some indecipherable reason harley indicators have flasher units in each indicator unit.
