During our trip to Wing Ding the CB on my 07 1800 with original battery stopped working. It had given me the occasional CB error message in the past, but on our trip to TN it went completely kaput. registering CB error almost immediately after starting out. If I removed the seat and unplugged the power connector and plugged it back in it would work with the seat off the bike while sitting still, but as soon as I started rolling the CB error message would come on again. As I had reseated all connectors minus the noise filters during my troubleshooting earlier of this I suspected it was a bad CB unit and talked to the owner of Wingstuff (place I purchased the CB from) while at Wing Ding and he agreed to replace the unit for me. I just had to send it to his company once I got home which I promptly did. It took a little while to process the return but a replacement came in and I installed it. As soon as I started moving the CB error message came back on, bike hasn't been running for a while as I haven't been riding it a lot this past month and it seemed like it cranked for about 10 seconds before starting but it started. Fog lights were on, when I turn off the fog lights I can hear a slight audible pop/click in the speakers. After the lights were off for a while and I had run about a 40-60 miles I turned the CB back on and poof, it works. As I have a feeling the battery is getting close to needing replacement due to other symptoms I'm starting to think the battery could be causing all this grief. Has anyone else experienced anything similar to this before?
