[TenTec] Troubleshooting Century 21 Power Issue

[Perry Ballinger]

Josh's idea of feeding 12V into the rear 12 Accessory socket works well 
but there is no overcurrent protection or meter reading.

I did this years ago when running the C21 mobile.  I turned the drive to 
where I thought it should be and didn't realize until later when I 
checked output with a Bird wattmeter that I was putting out
70 watts!  (Double the specification!)   Of course I turned the drive 
back, but I was amazed that the amplifier section was fine and no 
problems.  A tough little rig!
