All my electrical woes.
Didn't mean to sound nonchalant about the radio, but my big focus is getting the gauges. Scares me not having oil pressure/temp gauges working. Just pulled the panel out this morning to be able to get at things. I can trace wires easier now, so will switch the connection for the tach, trace the black wire to the ignition switch and see if make sure it is good and also look at the red/white radio wire and figure out what's going on with that.
At the airport now, so that stuff will have to wait until Tuesday.
Will post what I find later this week.
