Engine noise over IC, + wiring issues

[Guest jakescot]

Ride a 2003 RSV with a champion escort sidecar. RSV passenger headset wiring is piped into the sidecar and rider in car accesses with a plug just as bike passenger would.

There is extreme engine noise and interference over the intercom. Volume adjustment does not eliminate this static/whine/interference. That's one issue. Looking for help. I'm in the Seattle WA area.

 

The sidecar electrics operate off the bike. The SC is wired for hydraulic brakes, tail lights, turn signals. Lots of wiring under the driver seat. The problem is the bike often stops...quits, becomes a nice looking pile of metal/plastic/rubber. And I know zip/nada about all things electric. So any recommendations for a solution, in the Seattle area, would be appreciated.

I tell you, this is going to be a very difficult question to answer without being there to do some hands on testing. How often does the bike shut down? If it's a very regular thing, I would likely start by disconnecting the electrical going to the side car and see if that narrows the problem down. That would tell you if the problem is on the side car or the bike and then would be easier to find. If it's on the side car, I would then proceed to disable one thing at a time until I got the problem isolated.
