PTT not activating


 

I attempted to repair a failed in-line fuse for the ACC port and it appeared to have succeeded, however, the radio now will not respond to the PTT button being pressed on the microphone. The MH-59 microphone illuminates the DTMF LED when the PTT is pressed but no signal is generated. The radio otherwise continues to receive correctly, change frequencies and other settings, etc.

I am wondering if I may have damaged something in the area of the in-line fuse that would be affecting the PTT function.

Any ideas?
