Previous owner installed aftermarket led signals on the front and rear. They have the typical fast flash. Where in the system should I install the resistor? Or does each st of signals get their own resistor?
Any suggestions on what size Imight need?
Just installed a set of rizomas on my s4r the instructions says if u have a 10 watt oem bulb use a 10 ohm resistor if u have a 21 watt oem bulb use 2 10 ohm resistors in parallel not sure what the wattage is but they r the large white ones.hope this helps
it does, thanks.
whereabouts on the harness did you install the resistors?
On my 900, in parallel to the rear signals. I created a couple little sub segments with bullet connectors at each end, allowing me to just plug in the resistors. Then I mounted the resistors to the frame, behind the side pods to get air over them
Sounds good. Now i gotta figure out where and how to mount them. Its parked outside and i dont have a cordless drill (wanted to drill holes in the headlight ears). I do have some smallish p clamps. Was thinking of temporarily mounting them somewhere at the front on the trellis. Any ideas for a cheap, temporary, bolt on rig for my front signals? I suppose i could remove the ear bracket thingy but thats a helluva pain just to drill two small holes. I say temporary bc i am moving soon to where i can properly do the work but i just registered it and in NY i have 10days to get it inspected.
Put them under the seat with your rear signal wiring. you don't need a resistor on each corner, just one for L and one for R.
i just have mine ziptied to some other wiring. No need to get all fancy about it. Never had any problem with them over heating (until i put my battery in backwards that is).
Yep - just a pair, one for each side. I wired mine in to the tail so I could hide the wiring beter. As mentioned I mounted them behind the pods towards the back of original monsters, with the wires running along the sub-frame tubes - sorta stuffed under where I could
Thats what i needed to know. Thanks!
So I went to the auto store and picked up an electronic flasher relay (Tridon EP 35). The flashers now blink at a normal rate. BUT, if I flip the switch to signal, say left (or right) the corresponding side lights up very well but the other side that wasnt activated by the switch blinks with about half the bulbs lit.
Did I purchase the wrong relay? I thought just a new elec relay would solve this issue...
Do I now need to install resistors or just get a different relay??
Diodes on each side from the flasher will fix that. Sometimes that happens.
ok thanks Howie. Wish it were as simple as just getting a different relay. Alas...
If you order one of those flashers from the other post I put the link in, you don't need resistors. I ordered one yesterday. We'll see how it goes and I'll reply back ASAP.
Yes let me know. The flasher I got has the same number on the plugs though (49,49,31). So I'm curious if that flasher works with your LEDs.
It's a bit of a crap shoot as to how well electronic flasher will work with aftermarket LEDs. A different brand flasher might work. This one usually does http://www.ca-cycleworks.com/bmle-04 (http://www.ca-cycleworks.com/bmle-04) though it is a little pricy. You can also go the resistor route or, like I said, diodes. What you are experiencing is feedback through the relay.
Yeah I know...
Im returning my tridon and ordering the one from that link. "says" it dont need resistors. We'll see if ithandles thebleed over. I know that some relays have diodes and stuff intedgrated but cant seem to find them now. Had one on my last build project.
I got my relay today in the mail and put it on. It works flawlessly. I have a Clear Alternatives LED tail light with integrated blinkers on the board. I thought I remember reading somewhere that it has resistors built in. But with the automotive relay I was using, the Rizoma Zero signals I got for the front still wouldn't fire the relay without resistors. For me that's just more shit to have to try to hide in the wiring bundle. I installed the relay and took the resistors out of line with the Rizoma's and tried it. It worked perfectly and even has a very audible "click" like a relay is supposed to. I'm on the bandwagon about these relays and I'll encourage anybody to buy one.
Total price was just under $16 including shipping by USPS.
Thank you. [bacon] (my first bacon!)
I actually didnt wait and ordered the same one. Came today, install tomorrow. My added update to follow.
Yep. Agreed. Works like a charm. No extra resistors or diodes needed.
Just kidding. Looked too quickly and all flashers blink together. Guess i DO need a set of diodes. Damn!!
Yay! Looked in my electrical tool box and found a pair of new 3 amp 200 PIV diodes. Sure beats buying one for $7 + shipping!
Now I know that the diodes get joined together at their striped ends and then this union gets connected to one of the two wires coming from the signal warning light on the dash.
Question is: which wire? White/Green or White/Black? I suspect Wh/Gr but anyone wanna confirm?
Green/White is right side. Black/White is left side. Both positives. Black wires are ground.
Wait, so do i have the install location understood correctly? I was under the impression that my diode rig could be hooked up somewhere near the dash and would solve all four signals.
*edit: I just read on some random mc forum that if one were to pull the turn indicator bulb and cap off the wires that there would be no need for diodes. Zat true??
Wires clipped and capped going to the indicator bulb. Signals work just fine now and no extra wires! [clap]
Yes, but now the old couple in the Volvo following you for the last 6 miles will not know you just forgot to cancel the signal.
Guess I'll just have to be that guy
