truckernix, I re-set all the push buttons as suggested, and they all work properly. Thank you.
Both electrical connections on the radio are new and neither is fused. One connection goes to the on-off switch on the radio and the other connection shows no resistence to ground when tested with an ohm meter.
I will follow the excellent procedure in the tech tips and use the frame for ground connection but the connection that shows no resistence to ground would accomplish the same ground, yes ?
Is the electrical connection for the internal light connected to the on-off switch as well ?
There is also an electrical probe hole on the lower right hand front corner of the radio. What is the purpose of that hole ?
