Instrument Cluster Outage - Follow-Up
I fixed this a while back but never posted the resolution - so here it is...
In my case, the instrument cluster outage was intermittant - woudl work sometimes, other times (mostly) not. All fuses and connections seemed good. Fuses checked several times, including those apparently unrelated to the cluster itself.
Then one day, the vehicle stopped starting. Turn the key to "accessories" and the ratio and lights would work. Then "start", there'd be an audible CLICK, then nothing. Radio and lights out, etc. Leave the vehicle for 5 - 1o minutes, the accessories would come back on, but "click" - everything would shut off again.
Started to check various connections, starting with the Battery and found the Positive battery cable fried. Replaced that with a splice kit, and EVERYTHING has been functioning as normal for months now.
Odd as it seems, it was clearly the battery cable that was causing the problem.
