I’m going from step 4 to step 6 and then will come back to step 5… don’t ask me why.
There are three wires that the CB Radio installer needs to connect to the motorcycle. You can see them all in this picture. Two are ground wires (upper right corner). There is a beefy ground wire coming off the antena from step 2 that should attach to the frame. The CB wiring harness has a black ground wire and a positive red wire that needs to be wired to a power source. My red wire at the bottom of the above picture looks black because it has a piece of black shrink tube around it. It is recommended this wire be connected to a source that is “switched”. That means it should not connect to a power source that is always “hot” or always on. One reason is that if you forget to turn the radio off when the motorcycle is unattended it will drain the battery. So you are supposed to attach it to a power supply that is on only when the ignition key is on.
I hope I don’t sound like I know what I am doing. Finding the right place to connect this one little red wire was the most stressful and most educational part of this project for me. I broke out in a sweat just thinking about it. After calling two different Harley-Davidson dealer service managers and studying the wireing schematic in my service manual I ended up copying exactly the way a friend wired Diana’s CB to her motorcycle.
I found out quite a few things during this ordeal…
I found out my motorcycle does have a fuse in the fuse box that is meant for the customer to add accesories but according to one of the Service Managers I spoke to I would have to remove the fuse box to access that circuit from behind the fuse box. Too much of a challenge for me.
I found out there is one or two wires inside my motorcycle with a very elaborate mechanism on the end of it to keep it covered. This is specifically for the customer to wire accesories to, but it is always hot. It is not switched.
I found out there is a big gray rubber recepticle that is also for the customer to add accesories too but if you were to use it it was obviously meant to be used with a specific male plug to fit into this recepticle. If I am reading the wiring schematic correctly this is wired to the “accesory” position of the ignition. It is switched. Our friend had pulled one of the wires out of this recepticle to wire to Diana’s radio. I couldn’t pull the wire, so I snipped it. Then I cut the thick plastic conduit to acces the wire. See above picture.
I stripped the end of the wire, twisted the two wires together and then conducted my first soldering job! Also shown above. I remembered to put some black shrink tube on the wire before connecting them and then shrank it over the connections after the job was done. I think I did a pretty good job!
Then I went back to my ground wires. I had ground off the powder coating on my frame with a dremel where I attached them… but something was bothering me. I determined the seat would be resting on the wires after I put the motorcycle back together so I didn’t like where they were (pictured above). I decided to relocate them. I snipped a factory installed plastic tie wrap that was holding the tail light wiring harness in place in order to use the hole it was going through. I drilled the hole out slightly… probably just the powder coating inside the hole and not actually frame metal. Then I got the Dremel out again and ground off the paint to expose bare frame metal. I found a nut and bolt and attached the ground wire to this hole with the bolt. The downside being that the nut had to go up underneath an awkward place inside the frame that would not not be easy to remove at a later time.
I straightened out all my wires, used plastic tie wraps tidy things up and the wiring was done!
Note of apology - sorry blog universe for not writing sooner. Have had some family issues to contend with. I drafted this post back in January. At some point I got more involved in my family and my brain put some things on hold like blogging. Over the past month or so I found a new home for my parents, packed them up and moved them from Frederick, Maryland to my neighborhood here in Newark, Delaware. I am just starting to get back to some of my own personal routines. Man it feels good to blog! My fingers are happily tapping away at the keys! Thank you for reading.
