Factory Tach Stopped Working - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have an 87 K10 with what looks to me to be a factory tach. The other days randomly while driving the tach stopped working and is stuck at 4500 rpms. The truck is kind of a Frankenstein as the cab anyway was orignaly a 6 cyl and now is surely not. Axles are Danna 44 8 lug front and FF 14 bolt rear, seems like Blazer buckets and center console. I didnt do any of the work to the truck so i'm at a loss as to finding out whats what. All i know is the tach it has in it worked one day and doesnt today. Any particular things to check? Thanks!

Check the easy stuff first, make sure it did't come unplugged from the distributor and make sure it hasn't lost ground. I added mine, so maybe somebody else can tell you if it's on a fuse. Where did it usually stop when you turned off the key?
