Dual Coil with Points?

Some points have a plastic rubbing heel and some have a phenolic heel. The stock is phenolic and doesn't seem to wear. I'm not sure what the plastic is (nylon?) but it seems to wear much faster.
 
I was all set to tell you just how to wire the points to the new coil. Oh well, I guess you'll just have be happy using the Pamco. I sure am.
Heck, I'll tell you anyway.
Where the points wires come up and plug into the coils. Just hook the two points wires together, use one condenser wire. Hook allthese wires to one side of the primary of the new coil. Hook the pther side of the primary to power from the engine stop switch.
There you go. Now you know.

I hear that, I may just bite the bullet and get the pamco
......................hi you will not be sorry going PAMCO...... its a very wise choice..... and esay to fit..... looks neat... and goes great.... and petes help is superb... regards oldbiker .......aust.....
 
The #17-6803 is a 2.5 ohm primary dual output coil. Designed as a replacement for the TCI. Points use a 3.9 ohm coil as stock. A coil from the 3.9 to 5 ohms will work with points.
The lower ohm coils draw more current than the higher ohm coils.
points can't handle the higher current loads of low ohm coils.
You can use a low ohm coil with points but you need to add resitance with a ballast resistor. Most ballast resistors are from about 1.5 to 2 ohms. Hooking one inline with the coils can increase the ohms to a usable level. As in 2.5 + 1.5 = 4, or 2.5 + 2 + 4.5.
To use the #17-6803 coil use the ballast resistor on the power side of the coil. On the points hook both points wires together and hook them to the coil.
This makes both plugs fire at the same time. Just like the 80 up bikes.
RG, isn't this how you hooked up your Accel coil at first?

Yes Leo, that's correct. I used the same coil I still use (Accel 3.3 ohm, dual output), with points for the first year I ran the bike. A 1.3 ohm ballast resistor in series with the coil primary, reduced the current flow to prevent burning the points. When I went to the Pamco, I just by-passed the ballast resistor (ballast is still on the bike). The bike ran just fine set-up that way.
 
Your making my day, thank you.. Im trying to wire and fire this motor I picked up a few months back off the forum. I only have #17-6803 coils off my old motor... Now my next question is where I find these, google searching 1.5ohm ballast resistor isn't popping up very many results.

I don't think you searched very hard. I put "ignition ballast resistor" into Google and got pages and pages of results. In fact the very first search result has good information.
 
Your local tractor supply store has them right on the rack. A lot of older farm tractors use them.

I have an ACCEL 140405 with 3 oh, a solid state regulator and a set of 2 points in my xs2 from 1972. One capacitor or the set of 2?. Thanks! I HAVE NOT INSTALLED THE WHOLE STUFF, just in case...
 
Hello! What about the ACCEL 140405 coil? It is got 3.0 oh. And I´ve got a solid state regulator and 2 points system with a set of capacitors (I think will need just one). It is necessary a ballast resistor in order to increase the oh in the coil? Thanks in advance!

Yes, use a ballast resistor of at least 1 ohm resistance. An example would be the Echlin ICR 23, which is 1.3 ohms, and is sold by NAPA.
 
Hi out there, while on the subject, I'm also considering the Pamco ignition for my XS1b that I am now putting back together (or more correctly almost putting back together). looking at MikesXS there seems to be a couple different versions available for my vintage, the basic and one with e-advancer. Can anyone make a recommendation on which would be more suitable? I am not trying to create a race bike, just a good running reliable machine.
 
...I'm also considering the Pamco ignition for my XS1b ...

If your spark advance unit is as old and wore-out as mine, I'd recommend the version with the e-advancer. The friction of the points followers (rubbing heels) helps keep the worn/sloppy ATU rotated to its retarded stops. The Pamco rotor has no such retarding friction, and your timing would likely bounce more than before...
 
Good thought. Although I wouldn't consider 16k miles worn out, using the e-advancer would eliminate future problems.
Thanks for the input. Will let you know how the project comes along.

I bought at autozone the duralast AL795 and it gives 1.5 oh. On the other hand I put together the 2 points going to the capacitor. From there is going to the negative terminal of the ACCEL 140405. I grounded the capacitor body to the ground as well... at the moment nothing is happening. I forgot to mention that I added a switch between the battery and ALL the positive red wires. What I am doing wrong?. Thanks alot in advance!
