lookin to install a V.S. ignition and was wondering the best alternative to the scotch lock it came with. pictures or drawn diagram would be great
Cut, splice and solder the wire together.
Like Striker said.
or, what I did was use a triple female bullet connector from vintage connections and replace the stock double one to the coil power one. then use a single bullet from the red wire to the factory harness. r5 has even like that for 5+ yrs

a set of these connectors + the more common ones is something everyone w an rd should have IMHO. keep the harry homeowner connectors out of vintage bikes.
There you go, that's easier if you prefer not to solder.
"keep the harry homeowner connectors out of vintage bikes."
That's what i wanna do. So triple bullet with the double female end to the 2 browns at the coils, red wire from VS ign. to single male bullet and red/blk from harness wired(crimped) to the connector?
you can do it that way sure. or just replace the stock dual feed plug w the triple one.
is this on a 400 or a 250 or 350? if its the 400, and the stock ballast resistor is in place, you need to remove it and run regular 3 ohm coils. well, i would.
is this correct?
yup. you got it.
:thumbs:
thanks!!
Happy New Year !!
Got my bike fired up today! :whoop:..... But it's only firing on the left side. :bang: F! Coils ohm out ok so now I'm wondering if one of the modules on the vintage smoke ignition is bad. How do you troubleshoot the modules?
swap the leads to the coil left to right, then the plug wires. if it follows the pickup you know thats it.
You can also pull the plugs and ground them, they will still snap with the VS ignition. If one snaps and not the other double-check the distance between the pickup and rotor is correct, then start double-checking wiring for any shorts (that's what mine was) and of course the coils, etc.

still only firing on the left side. circuit tester shows power at both coils tho. is it possible to get a single pick up? where should i start tracing for shorts?
Mine had a wire rubbed through right at the too of the housing before connecting to the old points wire. I'd check around inside the housing first. A lot of vibration occurs there.
It could very well be a bad pickup. New ones can be bought from dyna.
I had a bad pickup some time back. First it was intermittently cutting out but finally died.
I swapped the pickups to prove it.
Pro tip: If your pickup is bad, buy a KZ or CB Dyna S kit from Ebay for 120ish. Use the pickup on your VS plate. Stash remaining new pickup for 'next time'. The secret sauce of the VS iggy is the plate, everything else is standard Dyna...
Also, be VERY CAREFUL with the tiny set screws holding the components to the plate - the aluminum is very shallow and doesn't hold any torque, they will strip/pull out easily.
Thanks for the input guys.
Diggin into it I found the brushes were hardly makin any contact to generator. Pulled the brush holder and one brushes was way shorter than the other(may not have even been makin contact to the generator). Then the solder connection broke to one of them. Could this be part of my problem? Rest of the wires seem ok so in the mean time I'm gonna see if I have some spares before I order new brushes.
Reverse the coil connections and see if the non working side fires. If it doesn't you likely have a bad coil or bad wiring to that coil. If it does fire, you know it's the dyna pickup.
man electrical gremlins really f with my head.

so it's lookin like i need to trace the grey wire from the coil backwards.
Swap the coil wires at the coils themselves (gray swaps with the blue one if memory serves me right). The connections are up on the frame near the coils.
Start with the pickup that you know works. For example, if the left cylinder is sparking, you know that coil and pickup is working. When you swap the coils, you simply are telling the left pickup to spark the right cylinder and vice-versa. If the SWAPPED coil is fine, then the right plug should spark. If the coil is dead, you'll get NO spark.
Proceed ahead if you get spark from both cylinders on the known good pickup, as you have then eliminated the coil as the problem.
The second pickup should cause spark since you verified its getting power if both coils test good on the swap you performed. If no spark, either the pickup is shorted to ground (frayed wires are common), or the pickup itself is bad and can be replaced as suggested above me.
sorted!!!!!
Chasing continuity from the coil back I found the soldered splice I made on the grey wire was f'd must have happened while fishing everything through the damn grommet at the case.
thanks everybody.
nice, good when its an easy win. :clap:
Good deal.
