Not really needing tech Help Stupid CMS wire

[snyper316]

I have said it time and time again there is something funky with my dash. Well tonight I pulled it out and went thru it again!!! As I wanted to make sure it was working I just had the unit in my hand. Well as I plugged it in, turned the key on to check it I bumped the Black Wires that run from the print board to the Digital Display. All the sudden Bam it blanked out came back with Warnings. So I moved my fingers and bam it did it again. So then while I was holding it I just put some pressure on that ribbon and All warnings went away!!! So I'm like O.K. You son of biscuit eater is that the way you like it... So fine I wrapped some tape around the unit put it in the dash and called it good. Which explains why I would tap on the screen and it would come back on. If I hit a bump just right it would blank out on me. So hopefully it is the last time I will have to visit this issue.:scratchchin:

Sometimes components actually go bad but more often it's related to connections. Sometimes it is wire connectors, sometimes it is ground connections and sometimes it is faulty solder joints such as the common issue with the Class and it seems like it's more often than not.

 

This is actually "The silver lining inside the dark cloud" because it means that troubleshooting electrical gremlins is often simply a matter of tracing out the offending circuit and checking continuity.

Frustrating is the fact I never just plugged the unit in first!! I always reassembled the dash and tested it after.

yup edge connectors on circuit boards are always a prime suspect in random acts of funkiness.
