Clock Not Working

I have a 89 b2200 and I just pit the speedometer/tach cluster in there. But yesterday I noticed that the clock rodent work. All I see is three little lines that go through the screen of where the clock should be. I I pull on the reset botton and look super close the clock comes on but just barly. And once I let it go it turns off and lines come back. Anyone know what's wrong ? If so please let me know. Thanks

sounds like a bad display

It could be a loose and or corded connection. Try cleaning and tightening the clock's screw.

If that fails, I have a clock from a tach cluster. $9 shipped USPS priority.

It might not be a bad display. Yes to make sure that the connections are clean and tight. The clock requires 3 wires. 1 for memory (connected to 12V+) one ground and one on/off (connected to ign+)

When going from non-tach to tach cluster you need to add 2 wires to get the clock to work correctly. There is a thread on it here and over on Mazdatrucking.com. I'll see if I can dig one up for you.

Here ya go. I've shared this here before.
