    Time to apply conformal coating on the two CCU boards as well as the Main Relay that I re-soldered after replacing it with the new one.


    This one is going to be returned to the owner so that he can keep it in his glove box as an emergency spare.


    All of them masked and ready to be sprayed.


    Now I just need to find some time to test these two boards using my NSX with test driving ...

    Recently, another owner sent in his CCU board to my place.


    It was intermittent but most of the time, nothing showed up on the display and thus, nothing worked.


    This board was the original spec so even if the NSX was kept in really nice condition, there is no chance in preventing the CCU issue to happen.

    Unless I can block several hours without being interrupted, I won't start the Valve Clearance adjustment service.


     As I couldn’t see it was possible to do so for the day, decided to work on the A/C Climate Control Unit (CCU).


    Another owner sent in his CCU board as well so it makes sense to work on them in parallel from efficiency point of view.


    This NSX that I'm working on at the moment is fairly new and ...

    The owner took my Health Check service last August and at that time, although it was recommended, the CCU board was not serviced.


    It passed all the standard test that I normally carry out during the Health Check and also the A/C gas level was slightly lower than the full but still performing well at that time.


    Since then, the owner only covered less than 2,000miles including the long-long journey to my place and reported that the A/C ...

    Fortunately, other area of the board were not severely damaged so only extra cleaning work was required.

    All capacitors are now upgraded and damaged tracks and pads were repaired.


    After checking the power circuit, it was safe to connect to my NSX so quick check before applying the conformal coating. ...
