I recently built some extension wires based on the schematic for the BMWLT >>> Older Goldwing at the link
referenced above, including the capacitors. Couldn't figure out why the caps would go on the speaker grounds...makes more sense that they would go on a mic wire as mentioned in a prior response.
If anyone can help me out, please tell me where I went wrong. I have an '84 Wing with a Chatterbox HJC headset built into HJC helmets. The helmets and headsets are only 1 year old, and I'd like to use them with my 'new to me' 1999 BMW K1200LT as well as my old Wing. Chatterbox doesn't make a 'lower cord' to mate with the 6-pin BMW connector, so I have the 5-pin male that mates with the Goldwing.
The extension cord I made had a 6-pin male to mate with the BMW, and a 5-pin female connector that mates with the lower headset cord.
Hope that I'm not hi-jacking the thread, but has anyone been able to successfully make a converter cord? When I plug mine in, all I get is a crackling sound. The bike was sold to me stating that everything worked, however the prior owner (2nd owner) didn't use headsets or intercom so I don't know if it works properly or not. I've read many threads on the dreaded BC1 Comm system, so I have my suspicions...
I've also read some threads where people made headsets from various Radio Shack parts. Any success stories on that would be appreciated. J&M said that they won't install in the HJC helmets (Chatterbox speakers are thinner than J&M), and if I need to invest in new helmets and headsets, I'd like to wait for bluetooth to be available.
Sorry for the long thread, but I've been researching the site for info without finding a specific thread on the Chatterbox HJC headsets. I also emailed the author of the schematic a few weeks ago, but haven't heard back.
Thanks in advance for any insight.
