Multiple Warning/Check lights

I have a 207 Electra Glide. Recently (last 2-3 weeks) I have been getting random warning lights while I am riding, the bike continues to run normally. The engine check light, red key light, battery light, and a bus error message come on randomly and go off randomly while I am riding. Recently I had to change the battery and the negative battery cable after finding the cable had been rubbed in two by the drive belt. I have checked all the fuses and none see to be blown. The codes I have pulled are: U1300, U1301, U1064, U1097, and U1016. Any suggestions where to start looking for the possible problem?

Looking at the codes, it seems that there is a loss of the serial data system, maybe a loose connector, If you have the FSM look in the wiring diagrams and follow the serial data connections going to the ECM. It seems that you may have a connector breaking connection while riding.

Could any of this wiring possibly be located in the front fairing?

Potentially, without a wiring diagram and a connector locator I cannot say for sure. But since it is a multi serial bus issue I would venture a guess that it would be closer to the ECM. I would even go as far to say check the plug and wiring at the ECM itself.

Thank you. I have a repair manual and I believe it has the wiring diagram in the back and it also has a CD with it. I will check it this evening after work. The reason I asked about the fairing was that I replaced the fairing speakers over the winter and I did not have any of these problems last summer and fall. Also the bike has a Dyno Jet Power Commander V installed which was on the bike when I brought it last summer but I did not know until about a week ago when I found it under the right side cover.

I hate to say it, but the PCV may be the culprit. It breaks the link between the ECM and the main harness so likely suspect.

I can disconnect the PCV and try riding to see if I get the same issues. Is the issue with the wiring harness that comes with the PCV or is it the PCV itself?
