Title: Impedance & Wattage specs for resistors to remedy fast blinking LEDs on 620 Post by: The ModFather on September 03, 2011, 09:40:55 AM Does anyone have these specs ?
Title: Re: Impedance & Wattage specs for resistors to remedy fast blinking LEDs on 620 Post by: OT_Ducati on September 03, 2011, 04:58:16 PM Trident EL12 variable load flasher, should work plug and play.
no adding resistors. $12.95 at Advanced Auto Parts Title: Re: Impedance & Wattage specs for resistors to remedy fast blinking LEDs on 620 Post by: Howie on September 03, 2011, 11:11:27 PM Trident EL12 variable load flasher, should work plug and play. no adding resistors. $12.95 at Advanced Auto Parts Not without major rewiring on a 620, the flasher is integrated into the instrument cluster. 5 watt resisters should work.

looks like its resistors for you Title: Re: Impedance & Wattage specs for resistors to remedy fast blinking LEDs on 620 Post by: The ModFather on September 04, 2011, 05:14:28 AM 5 watts but what about the impedance?
Title: Re: Impedance & Wattage specs for resistors to remedy fast blinking LEDs on 620 Post by: Howie on September 04, 2011, 09:01:19 AM If you get 5 watt resistors for a 12 volt system the impedance will be good. Your best bet might be to get the resistors from Rizoma.
Title: Re: Impedance & Wattage specs for resistors to remedy fast blinking LEDs on 620 Post by: Ohmic on September 06, 2011, 08:48:36 AM The stock turn signal bulbs is 10W. Not sure what your LED pulls. Assume they are ~1W at most.
Thus max (10W-1W) = 9W to have bike flash like stock. Ohms law... P=VI... V=IR... blah blah blah on a 12V system means it needs to pull .75 amps to simulate stock condition. Thus a 16 ohms resistor will do the thick. Don't go any smaller then that! Depending on the threshold of your flasher-relay might even get away with ~25 ohms. The bigger the resistance the better so you dissipate less heat. Because this is a 50% duty-cycle single you can use 15W rated device so heat will be at a min. -Bernard Title: Re: Impedance & Wattage specs for resistors to remedy fast blinking LEDs on 620 Post by: The ModFather on September 06, 2011, 09:02:18 AM and how would this be wired. In parallel is what I'm hearing. Does that mean one end of the resistor soldered to the positive cable and one end to the ground (black) cable ?
Title: Re: Impedance & Wattage specs for resistors to remedy fast blinking LEDs on 620 Post by: Ohmic on September 06, 2011, 09:14:38 AM Parallel of course. Remember you want to draw extra current to simulate a stock bulb. So you put your new resistors in parallel to your LEDs. One for each side. Simple as pie.
Title: Re: Impedance & Wattage specs for resistors to remedy fast blinking LEDs on 620 Post by: The ModFather on September 06, 2011, 01:33:53 PM sorry to be a dumbass but I just want to verify one end of the resistor to positive cable the other end to negative cable?
Title: Re: Impedance & Wattage specs for resistors to remedy fast blinking LEDs on 620 Post by: corey on September 06, 2011, 04:03:45 PM you know, i might have an extra set of resistors that would be plug and play... let me check the garage...
