Jackal Rear lights wiring

[Moda253]

Editing in the other half of my post… It only posted half my original.

I have to wire a new rear light set on my jackal due to age deteriorating the components and because of kids accidentally damaging it.


I bought some new turn signals which each have a green and a black wire and I bought  a brake light which has three wires. I wired everything up and everything lifhts up, except when I put a turn signal on, everything blinks.


I have a pink wire and black running to the right turn signal, a black/green and a black wire running to the left turn signal. Then I have a yellow, Red/blue and black wires to the tail light.

All the black wires run together.

So obviously I have something wrong.

I can put together a diagram of what I have going on.

Sorry my original post only posted half of my post for some reason.

It's okay - this post also blinks on and off as well - how did you do that?

[Kiwi Roy] should be along soon - I swear that man lies awake nights worrying about my electrical challenges, and I am a truly grateful Guzzista.

I suspect that the yellow wire at the tail light should be the ground for the tail light. Just a guess. The problem is at the tail light wiring for sure. You could pull the lense off the tail light and see which wire grounds the outside of the bulb socket. You could just switch the yellow and black at the tail light, putting the blacks from the turn signals with the yellow as well to the bike's ground. Good luck!

Without looking at the wiring diagram, I’m purty sure the yellow is power for running lights and black is the ground.
Usually on the plastic sockets it has problems with the contacts not making good contact if the socket deforms from heat. In the incandescent days the fix was to fit a replacement metal socket without any extra mounting flanges. I would heat a round something like a quarter inch drive socket to enlarge the hole and epoxy the new metal bulb socket in, paying attention to bulb to lense clearance.

A lot of aftermarket stuff is not made to automotive standard color schemes. Yellow becomes ground, black becomes running or taillight, red/blue becomes brake light. I may well be wrong, but I have seen this many times. Truck lights are commonly wired with a white ground and black and red to tail and brake. Someone long ago got house wiring colors into the truck and aftermarket light business, causing confusion at every step, especially without good instructions. YMMV
