View Full Version : Wire colors on 82' XLH
Can anyone with a 82' to 85' tell me what wire colors they have on each side
of their coil. Thanks Pops.

I am looking at the wiring diagram in the FM. From the ignition module a W [white] goes to one end and a BE [blue] to the other. A PK [pink] from the tach joins the blue, and a W [white] from the run switch joins the other white.
It is not clear to me which end is which. In the diagram it appears that the two whites are at the front plug end of the coil.
Hope this helps.

Does the direction of the wiring really matter? I'm thinking that the spark plugs dont care which direction the current flows as long as there's enough voltage to jump the gap.

It doesn't matter which wires are on which terminals. Two white on one side, a pink and a blue on the other (or two blue, or two pink depending on the year) - doesn't really matter much past that.
I thank you all very much. Chris and Gary I agree it shouldnt matter which
side the the wires are on as long as their paired correctly.
Now my only problem is that an 82 should have a breakerless ignition but
mine has the ig module but uses points and only has a single wire coming
from the cam cover and not the 3 prong plug like it should have. I'm thinking
this is a older motor which was a replacement for the original. When I stripped
the donor bike I failed to notice how it was wired. Big mistake but I would
think since it has points and no electronic pickup, the single lead from
the points would go to one side of the coil and 12V from the ig switch would
go to the other like a normal battery ignition. Sound right to you guys?
Again I really apppreciate your help. Pops(Mike).

Yes the white side is 12V, and the other side is the trigger side. So whatever your trigger is (wire from the points) should go on the other terminal.
The module may still be on the bike, but I can't see how they would use it with the points.
The '79 - '83 electronic ignition was crap, so I don't blame them for using points or a Dyna S.
Chris the module was still on the bike when I stripped it. I still cant believe
I didnt make note of those wiring connections. I guess I assumed they would
be original and easy to figure with a wiring diagram. Anyway the module has
the two wires you mentioned (white and light blue) plus the three prong
connector. The connector looked like it had not been plugged in for along time but I'm pretty sure the white and blue were connected to the coil but
does not make sense because its now a battery ignition.
I'm just about finished with the other wiring on the bike so I'll try starting it
with the white from the ignition and the black on the other side from the points and see how that goes. If you have any more input it will be
appreciated. Thanks Pops.

I would do just what you said at the end there: white to the positive side of the coil, black from the points to the negative side of the coil (doesn't matter on the coil positive vs. negative, that's just what they're called: +/-)
You might end up just leaving the module disconnected.
Thanks Chris, I'll post the results soon. Pops.
