2wheeltunes (2006)

[ΚĜΗΟŜΤ]

My friend has a 2wheelstune set up which was purchased and installed back in 2006.

An amp, 2 2" chrome handle bar mount speakers and a rotary disk volume control mounted to the handle bar.

Late last year and so far this year the left channel goes out and stays out and randomly comes on once in a while.

I have yet to look to deep into it so I thought I would reach out to see what the experts may have to say.

I did take the rotary volume control off and apart. It is a small PCB with a very simple round disk attached to the PCB which rotates. Three wires attach to PCB on each end.
Red, White and shield. Both sides of PCB.

Not sure what those wire are for and where then come from or go to but I assume they go to the amp.

That is all I have so far.

A schematic or wiring diagram would be great.

If anyone knows a bit more on how the system is wired, what may be causing the loss of the left channel and/or where to look for what.

Would be appreciated.

Thanks
Jack

My guess would be damage from long term vibration in the unit itself, a cracked board, loose solder joint, or one of the drivers has failed. Is it possible to switch the speakers to rule them out?

Yes I also found that redirect. Issue is the components they sell are no longer 2wheeltunes.
That volume control pcb has the name 2wheeltunes printed on it. So at that time they had the accessories made and branded for them. or so it would appear. Stereos have come a long way......
