Here we are several months later and I still have no running bike.

Can someone who knows a little about electrical systems and coils help explain why I have voltage to my Accel coils ONLY when I'm touching the towers.
Yes I have voltage INTO the TCI, over 13v.
I have nothing coming out unless I'm touching the towers that the grey and orange and red/white wires attach to. Why?!?!
Coils are grounded by brackets AND I added another ground to frame under the brackets.

If any one is in the Orlando area I'm willing to PAY for help!

can you post a photo or two of the wires as they are now? It would be nice to see the wires at the coils, with the plug wires on the plugs, the pickup coil wires under the left crank cover, and a photo of the right hand control, as that is the kill switch area, a possible problem.
If you can't post, email to ray(at)rjmatteis(dot)com, and I can have a look at them.

Hey Aggie,

Aside from posting/sending the photos, would like a little more clarification of what you mean by touching the "towers" of the grey/orange and red/white wires??

You have the 80 year which still uses the ballast resistor. You have Accel coils, but don't know if you have the 3 ohm or the 1.5 ohm type? If the 3 ohm type, you need to bypass and remove the ballast resistor.

The TCI routes power to the ballast resistor only after the engine is running. During the starting mode it bypasses the resistor and sends power directly to the coils to provide the full batttery/12V+ power for stronger sparks. It's expecting to have OEM 1.5ohm coils and they would burn up with full 12V all the time, hence the 1.5 ohms resistor to drop the voltage down to ~9 when running. The TCI will see 1.5 ohms with resistor and 1.5 ohms in the coils for a total of 3 ohms. With newer 3.0 ohm coils, the Ballast resistor isn't needed.

Can't help with the local Xsive, BikerPhil lives way south near Ft Lauderdale, so may be too far for him to easily travel. You may be able to post in the Member's Forum for anyone closer to the Orlando area.

Visiting Orlando.....but not too soon...

I plan to be in the Orlando area at sometime in the next few months to visit one of my very best friends. Unfortunately, the time line has not yet been determined probably something like early December.

Otherwise, drag it up I-75 to ATL and I'll make it run.

Best I can do.....

I'm in Orlando but not an electrical guru but have good luck getting things to run....I believe i have an 1980 special wire harness and coils if you want to try them out to see if the bike will run. Could point you toward your real issue or at least rule some stuff out.
1979 F worst one i could find
to convert into a bobber/ streetfighter!

We can't all get along!

The 80 Special has a different wire harness. With that said, two people looking and trying is ALWAYS better than one frustrated person.
When you are both there, try these two items.
1. Bypass the kill switch. It's the red/white and black/white wires going to the right hand control, IIRC. The connector has the start blue/white, kill, red/white in and blue/white out. Disconnect the control connector and jumper the two red/white blue/white wires. Then with the right side cover off, you can jump the starter with a short bit of wire on the solenoid to try and start the bike.
2. Disconnect the 4 prong connector from the TCI. Use a VOM to test the resistance between White red and white green, bottom two, for 720 Ohms, then check Yellow red and yellow green, top two. If the resistance is between 660 and 800 Ohms, you are just within specs. If you have one at say 760, and the other is at 860, you have a problem with at least one pickup coil or wire.

I sound like a broken record to many here, but ensure that it is in neutral before you jump the solonoid or it could roll off the sidestand!
