Factory tach not working - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Found a factory tach cluster on eBay. Putting it in my '86. Everything works but the tach! Bought new wiring harness from LMC for tach. One wire to distributor. One wire grounded. Other end had pigtail that didn't plug into my harness so cut off and spliced on male end plugging in directly to fuse panel. Plugged in to back of tach....nothing.

Thoughts? Bad tach?? No clue if it worked when I bought it, but was told it did.
