Dan I am sorry I did not know where to put this ... As you can tell I am still researching my off the road situation.There is a photo I will try to load to gallery and post it from there.. If not forgive me for posting here..
I think it might have helped me , not sure yet, but it might help others trying different coils and not overheat older wires.

For use with DYNA or ACCEL 3-ohm COILS: Reduce load and heat in your stock wiring while increasing your spark plug performance.
This Resistor Pack is used to match low-ohm primary coils to the vintage Honda/Kawasaki/Suzuki/Yamaha bikes with points and coils of (normally) about 4-5 ohms primary impedance.
Technical Details:
The typical vintage Japanese wiring for the Ignition Coils is sized to carry about 3.3 amps of continuous current, while the stock coils draw 2.4 amps on most bikes of the era. The 3-ohm coils from Dyna and ACCEL draw over 4 amps, which heats the stock wiring quite a bit. The wiring connectors and the handlebar RUN-OFF switch slowly grow damage from continuous use at this higher current. This Resistor Pack reduces this current to a safe level (2.8 amps) for the bike's stock wiring, while still allowing for a nearly 3-fold spark voltage at the sparkplugs from using these high-output coils.
The Dyna (Green) coils and ACCEL performance coils have 3-ohm primaries: these require a 1 ohm Resistor Pack to match these bikes' wiring (and charging) systems to those coils.
The Dyna 2.5 ohm ultra-high voltage coils (or 1980 and later Honda coils) require a 2.0 or 2.5 ohm Resistor Pack when used on the SOHC4 motorcycles, depending on the bike: contact
[email protected] for more details. Typically, this is only for off-highway applications, as the alternators on these vintage bikes don't support these high-draw 2.5 ohm coils very well.
Shipping: $7.50 in the U.S. and Canada. If the "Postage Machine" overcharges you for (overseas) postage, a refund will return to you after shipping.
Other (custom) resistor ohms values are available on special order: contact
[email protected] for details.
NOTE: On the alternator-challenged CB500/550 bikes, this Resistor Pack can allow the rider to use the Dyna 3 ohm coils with either stock points ignition or the Transistorized Ignition. It will not, however, reduce currents enough on this bike to allow for BOTH the Dyna S triggers and the Dyna 3-ohm coils: that is just too much load for the mid-sized Fours to carry. The CB500/550 rider may use EITHER the 3-ohm coils with this Resistor Pack, OR the Dyna S triggers with stock OEM coils: using both will cause electrical overloads and low battery charge problems, due to the smaller alternator output.
