I don't have a video but I traced the wires from the after market alarm system that was installed from the pervious owner. It ended up terminating in the middle of an oem wire (forgot what it ran to). Since then nothing has went bad. I believe this problem could also be caused by being connected to the ignition system incorrectly. I'll drop the link if I can find it.

 

I have repaired a few of these but there is a power supply made by alps that burns out.
It creates AC voltage and -8VDC to bias the VFD display.
What I have begun to develop a modern replacement

This is the proto
This is going to be based on an ESP 32 processor. There will be a WEB interface to set up and scale.
looking at adding a few bells and whistle. I have to build at least 10 to make it cost effective.

 

This is pretty cool. Let me know about the progress!

 

those are AWESOME. I was able to get mine fixed, but I’m not stopping either. I’d be super interested in being apart of this though, especially with the potential for bells and whistles. There’s so much unused space. I almost thought about doing the projector idea to the wide, sleek dash.

 

Any updates!?

 

Unfortunately, the capacitors on the green board have been changed. E. Can you tell me the value of all of the green motherboard? C1 c2 c3.... Thank you very much

 

Please don't give up on this project. I would love to see this finished!

 

if its possible could you please share the pins - how did you connect to car?

 

im interested in this thread, i have an issue with the speedo needle going out. My car is in storage but it would be great to find a replacement for all the EL dash as i know the rest will fail over time

 

Hello, my 94 si fuel temp and engine temp gauges finally died over the winter. Need to get it fixed or replaced but have no idea where to start. Any advice is much appreciated!
