I may have finally fixxed the tach
after opening up the tach here at work with an electrical guru, we found that the 3 leds used for the needle are wired wrong. they are wired to pin 3 (tach) and 8 (ign +12) should be pins 4 (ground) and 8 (ign +12). i will take this home tonight and give it a go.
brain fart while re-soldering the wires ended up doing pin 4 (ground) and pin 7 (backlight +12)
woot! straight to the garage and... it werks !
needle reading 3k at idle so I reset the needle to 1100 @ idle hits rev limiter just past 15k. perfecto
the recolor looks so much better when the needle moves.. now to do the LCD reverse color.
Thank you to all the helpful members that tossed me info. I gave up on it a few years ago then suddenly it was ever so important to have working again.
