Difficulty Difficult? this is the easiest thing you can do to one of these radios.
thank you, i’m hoping this will help but i doubt it, i had too big of a fuse in mine and it took a spike hit and lost all power a few years back but i’d really like to get this fixed.
Any idea what the board pin hole number is that the black cord from the negative goes into? I’ve got a 2018 29 LX
Not sure. There is a partial schematic available at www.cbtricks.com
