need some help, iv been troubleshootong all day now,,replaced struts on a 05 ridgeback all done fired it up and no right light nada nothing, ok,, swapped led with other side,both good,,thought oh shit i pinched a wire, took strut back off ,wire looked good, followed wire back to plug by ech, looked good,,thought ok maybe maybe plug(harness) maybe pulled a wire out,,stuck wires in and get nothing,,so my question is ,does the ech shut down one light if it senses a short? if you pull the harness off the ech can you get acess to the wires and female plug terminals? there are 3 wires, red brown black,,what are the function of these? god i hate electrical problems,,will the ech reset if it tripped somehow,thanks for any help u can give,, i am hoping the problem is in the plug 3 inches from the ech,,has anyone cut this out and wired direct?:spank:

Should be Red/Brown/Black on one Side and Red/Purple/Black on the other. Power/Brake/Ground. The two off color wires should provide the additional signal necessary when you brake.

If you can swap the LED's I'm with you, its either wiring or connection.

Check the pins and connection on the plug which goes directly into the LED, make sure you didn't break something there. Some people have broken the pins and have just put a bit of silicon in the hole to hold the wire in place.

I'm confused by your second post. Upon initial fireup of the scoot did bot tail lights work? Then you hit the brake and lost one?

What light(s) are showing on the EHC when you press the brake and/or activate the turn signal?

left side works fine, light ,turn, brake,right side completely dead,, swapped boards(lights) to left to check them , the bulb i took out of the right side, the brake light function does not work, (will not go bright when brake applied),,if the brake function on said board(light) fries will it short out up all the way to the ech and damage the ech or trigger some kind of shutdown? just bought a new light from shovel on ebay,,gotta replace one light anyway but worried it may have damaged ech??? any input

I gather you didn't look at the EHC as I asked? Anyway, if the right side is completely dead I would check the ground (black) wire to make sure you have continuity from the lamp connector to the EHC...

Dennis

PS It shouldn't have damaged the EHC. It has internal protection for stuff like this.

I asked about the EHC lights but I made the mistaken assumption that the bike was together.

I don't know what you mean here! Nothing is connected? The wires are completely torn out of the bike? Or what?

If there's nothing wrong with the wires why are you replacing them? Did you use a multimeter or are you going by looks? And if you're planning on replacing the wires, do you have new connectors to crimp on the ends?

Why would you want to? If your lights worked before you changed the struts and they didn't work after then it's something you did! You're barking up the wrong tree and asking for trouble by messing with the EHC connector. A multimeter will tell you everything you need to know...

Dennis

PS Got any pics of what you're working on?

Honestly, I'm still lost!

Looks like you already ordered the LED but check the voltage with a multimeter as DRBarnhart says above. Let's start there, and I highly doubt its the 6 pin connector that runs from the tail light harness to the EHC if it worked prior to changing out your struts.:up: Touch one to power and other to your ground when bike is turned on see if you got juice going all the way out at the tail light.

Also, you mentioned something about crimping the wires. After just rewiring my tail light harness I would advise soldering and using shrink wrap. Your not going to get a good connection any other way.

More than a couple of folks have jumped to the conclusion that their problem was the EHC, installed the WP, and then still had the real problem to fix afterward. The reality is that a majority of the Big Dogs out there are happily cruising down the road with their original EHCs and have never had a problem...

Happy riding!!! :cheers:

I noticed you were from the UK so I looked up Axel from Electronikbox.de. Axel Joost is one of our members and is very accessible. Give him a PM and he will be able to help you. This is his site and I'm pretty sure this is the LED Insert you are looking for. https://www.elektronikbox.de/shop/i...oduct_info&cPath=7&products_id=10&language=en
