LED wiring question

Hello All,

OK, the reason I do mechanical things for a living is that I have trouble performing simple things electrically...........

Here is what I did, your job is to tell me where I should check to see the errors I have made..............

I removed the rear turn signals in my motorcycle. I am trying to install a set of LED turnsignals (mounted in hard saddlebags) in their place. bear in mind that I bought them used, through ebay.

I used a solid, not stranded 18 GA wire and soldered my connection points by winding the existing stranded wire around the solid wire then soldering it in place. ( I thought I bought stranded wire but it was solid. After I finished the connections it seems there is no power being sent to the LEDS. Believe it or not, I can usually solder wires together? Is it possible that even though I soldered the wires together I have a bad connection? the more I think about it the more I think it may be hard to connect stranded wire to solid ??

Could it be the lights themselves? it seems odd both sides would be bad? How can I test them?


thanks for any help and / or suggestions as I am stuck here

Stan

You should get voltage through the wire unless you have a really cold solder joint. i would go get some stranded wire as solid wire will not take the vibation on a bike. That is the reason all mobile wireing is done with stranded. Take a volt meter and start checking to make sure you have voltage before and after the splice. don't assume that you didn't blow a fuse or accidently pulled out a connector somwhere. If voltage is present on all points assume that the led's were bad. Another possibility is that the dropping resisor was not the correct one for 12V.

LED only light one way. You can try reversing the wires. They are diode and they work only one way.

Thanks, I'll swap to stranded wire. Would it be OK to use crimp connectors?

Before I soldered (or crimped) anything in place, I would bench test the lights (or any other accessory) to be sure they work, and that the pos and neg wires are oriented correctly. JM2 cents W

Stan, be aware that the rear directionals are different from the front in that they are marker lights as well and do not light except to flash to indicate a turn. The fronts are on all the time the motor is on. Additionally, there is a problem in that the flasher unit works with a current draw on the circuit which you will no longer have with LEDs. Hence, the lights will not flash because they don't draw enough juice to activate the flasher.

Lastly, take out the solid wire and replace it with stranded. In the absence of a voltmeter take your old bulb that you replaced and put it in an appropriate socket with a couple of wires and use that to check and see if you are getting conductivity through your connection.

Good luck.

another thought on this.... did you get the load equalizer as well??? I have read that our thermal flasher can't handle LEDs.
