I just got a new pair of flushmount turn signals and wired them up using this diagram http://hooliganbiketech.dynup.net/hondacbr1000rrweb/1000RR_Mods/1000RR_mototeck/mototeckwiringdiagwithrunninglightdiodefix.htm

and when I wire the turn signal and run light together it makes the signal dim as opposed to when one or the other is hooked up. Is this because the wires for the turn signal aren't large enough or there isnt enough current or voltage going to the turn signals? Has this happened to others who wired there turnsignals up to be running lights as well? Thanks guys for all the help.

 

resistors may help

 

Are you sure you had ground, running light, and turn signal correct? i.e. did you use a multimeter to test continuity to ground, and power on running lights and turn signals? So you DID use Diodes?

There is plentyof voltage and current even through 22 gauge it would be fine. There is only 21watts or so going through those bubs, and I think this is 18 gauge.

Are these LED turn signals? like they have a polarity? IT sounds like you have turn signal and running light switched, or the ground is being bypassed.

I would check your wires again, one at a time, start removing variables that might be causing a mix up. One reason is the diodes are such a pain because they ALWAYS end up causing problems like this. Test for continuity on every wire, and also whether it's getting 12v, because it may be basically shorting out instead of switching to the alternate turn signal.
