The next part of wiring up my aftermarket gauges is to wire up the turn signal relay. It seems pretty straight forward but I merely dabble in electrical and would like a more experienced eye to review my work thus far.

Any help is appreciated. The only thing I see as an issue is if the dash LED (lamp on the upper right) burns out the turns won't work, so I'll probably run that parallel instead of serial and send it to a discrete ground.

Ignore that one for a minute, just realized two problems with it. Stay tuned.

Lol yeah, too late in the day to try and draw these things... I make signs. Really good signs. Don't let me rewire your house.

Refresh your browser, I relinked to a revised one. I still don't promise it's even close to right, but humor me. Shit... humorless... I'm screwed.

I don't see much different.

What is to stop all 4 bulbs from lighting at the same time?

Photobucket screwed up, I relinked it with a new name. With the original one, nothing was stopping it, would have been disco fever.

The only thing I'm not certain of is feeding the switch through the indicator.

Not only will the turn signals not work if the bulb is out...I don't think you'll get adequate voltage to the switch because the filament acts like a resistor.

flasher relays goes between the switch and the flashers as well, right? and yeah that indicator lamp should be in parallel to the circuit after the fuse

The factory feeds the switch through the relay. I think that will work OK.

If you just wire the indicator in parallel I think you have it.

All will work fine as it is, with the following changes:

1) power your turn indicator from the output of your flasher relay and then send it to it's own ground.
2) you mention an LED for the flasher indicator.  Unless you're powering a factory LED, you will have to compensate for the voltage difference between the 12V bike & the 3V LED (IIRC they're 3V...)  ((factory LED's have boards to change voltage already...))



That should do it!

Just remembered, LED's are 5V DC and not 3...

Add to this: If your indicator light burns out your indicators will stop working.

I own several motorcycles. I have owned lots of motorcycles. And have bolted and/or modified lots of crap to said motorcycles...

Here's what I did. It works great:



Basically you tap into the + wires for both indicators (left and right sides) and wire in a diode before connecting the "tap" into the + lead for your indicator LED.

Then just wire the - on the LED into ground.

The diodes keep the current from flowing backwards and lighting up the indicators on the opposite side. A diode only lets current flow in one direction (the direction of the arrow, or the band on the actual diode) and are rated up to a certain voltage. Radio shack carries 24v ones which should be plenty good for what you're doing.

The drawing is crap, but what do you want for 5 minutes work in Office  ;D

Duh... cause the circuit for the flasher wouldn't be completed, triggering the relay, until the switch was turned on. But yeah the indicator lamp would need to be in parallel to the relay or it would flash too... right? 2 years of vocational electronics. guess i'm a bit rusty lol

The indicator is supposed to flash. ;)

And it will in parallel or series.

Time to hit the books. :P
