9 pin connector - dash cluster - 69 'Cuda
long overdue update, cause I just had time to get back to this.
while the dash was out we took the time to "'refinish" the dash surround.
- sanded the "chrome" areas
- replaced the woodgrain with new aftermarket
- sprayed new Duplicolor chrome paint
It looks much better than before.
Also painted the gauge needles neon orange, tach needle came off during this process, but I think I got it back in place, (that's another thread).
Also cleaned up the heater box and associated bit.
I ended up snapping a pin on the PCB for the 9 pin connector, could have resoldered, but bought new aftermarket (heaterboxguy?). The PCBs seem well made and the 9 pin connector pins are much more robust than factory.
I started this project because oil pressure gauge was non-responsive.
IT NOW WORKS, but most likely because I also replaced the sender.
The sender that was on the car showed no resistance change when I pressurized it with air.
Constant 70 ohms or so.
The new sender varies from 70 - ~ 30 ohms when pressurized.
Sadly, the tach does not work.
I either didn't connect correctly, or the needle is not seated correctly.
Off to research correct wiring connections on back of tach, one eye connector on a post and one push on connector on a post.
really hoping it is wire error and not needle issue
sob.
Thanks for the earlier help.
