Gauge circuit board

[TkerJker]

So the never ending 928 project was done or so I thought.......................sigh. Apparently after several thousand dollars and several hundred hours my customer would like his speedo to work ALL the time instead of when it wants to. Fair enough, I see Pelican offers a Speedo head which I know is most of my problem but the circuit board is also in very rough shape (car sat with no windshield in a compound for oh 8 years..........) so has corrosion and what not, does anyone know where I should start hunting for a circuit board? Is for a 1982 928S I think...... I know when it was smashed it had an S front bumper cover etc.


Thanks T.J.

Check the 4 pin connection in the spare tire well, but likely its the circuit board, not likely its the speedo, but the odometer does have a gear that goes bad and should be replaced with any cluster work.

Are the possible sources for a new or used circuit board.

If it helps speedo doesn't work so push and hold odo reset button and 9 times in ten speedo will work cleaned and lubed and checked all contacts, tightening as required while car was being reassembled. (was a porsche in a box came to me in pieces and had a hard hit on rf). Thanks for info will look into those sources.

By the way most of the brand new circuit boards I've seen run about $100-$130. Don't forget about 928 specialists. I bought one for my 79 but I am ending up hard wiring each component and light to some solderable D-sub connectors (old school computer printer connector, the one with 2 or 3 layers of pins) because I am tired of sanding contacts and wiggling connectors. I'm using 16 and 18 AWG fine stranded wire and rosin core solder.
