Hate to say it.... your tach board is fried. Sorry...

The link on the 75-77 board won't be up until Tuesday... But if you hardwired it and it is still doing the same, the problem is the board.

I'll post again when it's up and running.. We did the final test on the new boards a week ago Friday.. Had to make a move in one of the Caps... But they should be ready on Tuesday for shipment.

Also, I have some info on the boards at this link.. It's 78-82 but for the most part it's the same. http://willcoxcorvette.com/repairand...lp.php?hID=290

When the boards are in hand on Tuesday, I'll turn the links or and start work on the help page for the 75-77 boards.
