Batboard

Hi,

Have a spectra dash mount, it appears that the control head has a problem powering up the radio. Switching control heads and radio powers up. Any suggestions.

I'm having trouble remembering the specifics, but let me ask: Do you have ignition sense going to Pin 5 of the accessory connector on the back of the radio?

Normally, you need B+ on Pin 5 for the radio to power up. I seem to recall that there was a mod that could be made to a control head to end-run this, and that may be your situation.

run a search on here and you will find which capacitors need to be replaced and cleaned up.

There is also the problem with the IGN circuit trace on the control head board burning up. Kind of hard to troubleshoot without a extension cable so you can work on the back of the controlhead board.
