allrighty...
tach worked fantastic before paint.... now everything is reassembled and the tach doesnt work.... mallory CDI box with modded tach (see CDI tach mod) worked flawlessly, and a late gauge would work fine too... now, early modded tach doesnt work, nor does a late model tach. i checked gauge connections, and i checked engine bay connection. the blk/purp wire connects to tach output of CDI box, and is plugged in at gauge... where should i be looking??? no signal is making it to the tach...

Get a volt meter and check continuity of the black purple wire from the coil end to the gauge end (broken conductor). Then check the black purple wire for continuity to ground (short to ground). Check fuse S-9 (74). Check the red and white wire from the fuse to the gauge for continuity and short to ground if blown.
