HPR4232: Replacing backup batteries in my Kenwood TS940S HF Radio Part 6

Picture 1

Shows me attaching the leg of a resistor to the new backup battery. This is to extend the battery terminal length so that it can be soldered between the two connecting battery posts of the radio Printed Circuit Board.

Picture 2

Shows the newly fitted PLL backup battery with it’s extended terminal fitted directly below the EPROM labelled JAF7.

Picture 3

Shows the speaker sitting within a metal box. This box sits on top of the screened metal box housing the PLL backup battery. When I was refitting the speaker box I discovered there were extra badly soldered grey wires attached to the speaker terminals. The other end of the wires was covered with black electrical insulating tape. I removed these extra grey wires from the speaker to prevent them from coming adrift and or causing a short circuit within the radio.

I mention the trick of using blue-tak to hold a difficult screw when inserting it into a tight recess. Wikipedia article about Blu Tack
