Question about Harley Davidson 426290 AM/FM Radio
This radio/cassette player essentially has no sound. It belongs to a friend and he tells me it has no sound/volume. It's on my bench and it has a 23 pin input which I assume I can fabricate a harness to power it up and troubleshoot. I've not found much info but assume when installed there is a remote wired controller on the handlebars. Anyone know of schematics for this monster or common problems concerning the volume control. I prefer not to tear into it with a multimeter without any direction, although I will if need be.
No / intermittent audio is caused by vibration damage to the audio circuit. Unit needs to be put under a microscope and inspected for micro cracks in the solder joints of the audio circuit components.
Volume control is adjusted by remote switch on handle bar. You can contact HD for a wiring harness schematic
