Carrera Gauge Swap

[KevinH1990]

I am continuing my effort to install a Carrera Gauge cluster in my 2000 Boxster. The Carrera cluster has a damaged clock/oil gauge lcd and you can see here:



I haven't found anyone who can repair a broken lcd, so I thought I would try installing the Carrera Gauge faces on my Boxster circuit board. You can see the results here:




When I use the Carrera gauge faces on the Carrera Board, everything works OK with the exception of the damaged lcd. (It works, but it is unsightly.)

When I use the Boxster circuit board, every works OK except the voltmeter. As you can see in the first picture, the Carrera/Carrera combination reads between 11 and 12 volts when the ignition is switched on. The second picture shows that the Carrera/Boxster combination reads 0 when the car is on.

(When the car is running, the oil gauge reads between 4 and 5 with either combination.)

Any suggestions on what I might try next? The circuit boards appear identical and have the same part number. However, there are so many components on each that it is not possible for me to be sure they are identical.
