Instrument cluster grounds
Ive got the dreaded pulsing dash in the 94 in the LCD day or night
I figure I would start with the grounds
Can someone tell me where the grounds are?

My 93 was going dim on me off and on. There may be several grounds on the chasis but the one coming directly off the battery is grounded to the chasis right behind the battery. Once the bat is removed you can follow it to were it connects. That didn't solve my problem though. I took the speedo out, pulled each one of the bulbs off and put them back in to "redo" the contact. I replaced the 2 bulbs right behind the speedo screen and reinstalled the cluster. Since then all is good. I think mostly it just needed to be pulled out and put back in.
The ground I'm talking about is the small black wire, not the main battery ground

Just for kicks and because I am not sure about the later models.
Batee.com correctly points out the larger heavier components hanging on a PCB...the rattling and vibrations coupled with time lead to the solder points breaking.
He points out how to reflow many of the ground components with a soldering Iron in order to reconnect those ground points within the PCB. This is consistent with taking out the cluster to Pug or unplug the connection to re-establish a proper ground.
Some one else will have confirm if the later models suffer like the early "Atari' dash does....
