New ignition test?

[HobbyMan]

For some time I have been riding with my AM/FM/CD player. THe other day I got it stuck in the AM mode. Now it works fine, but I discovered that there is a lot of noise from the electrical system. Youy can clearly hear the rpm change. At low ranges, it is a buz and at high rpms it is a high pitched tone. My radio is situated in my homemade saddlebags right beside the seat up next to the grab bar. Would this noise be directly from the TCI or the spark/coil assembly? Anyway, I fixed my pickup coil wires a while ago because they were broken in about 6 places. Now they are broke again in a different spot. I can hear the miss when I change the advance position. I am bored and just thought that this is an interesting way to find out wheather you have ignition or fuel problems. What do y'all think?

I dunno about all that, but.....
My apartment has a gate which operates via a radio button.
Works fine in the truck, but on the bike I have to hold it way up in the air away from the bike before it will operate the gate. Leads me to believe these things make a lot of electronic noise.
I gave up and just use the keypad now.

The wires for the spark plugs are "solid core". They WILL generate a LOT of radio frequency interference. I use a resistor spark plug, along with the resistor caps on the ends of the wires. The stock coils seem to still work well, and my noise is way down.
Hobbyman,
I would just replace the length of wire with black and red "lead wires" from radio shack. If you go up the wire harness from the coils, you can see the crimp from the factory. Use a small bit of heat shrink tube to "color code" the wires.

My garage door opener works fine, even in my jacket pocket while I am sitting on my bike (engine running). I think that this is something that will require a little more research and testing. It is very hard to tell a miss because the engine RPM changes. I think I am going to go out and recod the audio in sequences and break it apart on my computer. I think that this would be easy enough to analyze the frequency changes. If anyone with any gurudome in the electronic field wants to input on this subject, that would be great. Since my bike is such a joule to me, I would like to have it run well. Sometimes I feel Bipolar about it. Watt does everyone think on this subject?

I am going to replace the flexible part of the pickup couil wires completlely. Last time I fixed them, I did not realize how close I was to the junction of the flexible and harder wires.

Resistor leads..

The problems I had with Pathfinder was caused by those resistor type high tension leads that were put on the stock coils. There is no wire inside, just carbon. It made the spark so weak it would only fire a weak mixture. I also had a sterio on the '79 standard I had before and listening to AM was impossible, but FM and the tape player was OK.
