Bose AMP, Audio Head Unit, A/C CCU Board service 03

Rate this Entry













The CCU board.

Lots of scraping, hard wires, jumpers, soldering bridge, etc used to recover the damaged pads and tracks.




Initial bench testing went fine so time for the conformal coating and about to be tested on my NSX.




Not sure I should test it today as it’s so hot inside the garage……








The audio head unit.
The upper side of the board is now cleaned.

At least, one of the track has completely cut through.
The owner told me that he lost the power completely so probably this is the track for the On/Off switch but haven’t checked it yet.

Cleaned the OP AMP section.
The diode changed its colour but at least, it’s still functioning. Not sure under heat though…..


Will carry on servicing them together with test driving another NSX although I may need to replace the Main Relay first.....
I don't want stalling the engine at the roundabout under this heat.....


More to follow later.
