86' Turbo - boost gauge does not point to 1 bar when key is turned

Hi all, wondering if anyone has any ideas on where to start on this.
I'll be driving and the gauge just seems dead. I feel like boost is happening and then every once in a while the gauge will show boost and work for a while. Seems intermittent. I had the gauge cluster out and the resistors didn't look cooked at all. Even after putting gauge cluster back in car, it will not initialize to 1 bar when the key is turned.
Thanks - Paul

He has extensive experience with that very gauge
EDIT: seems the website forum group I am referring to is censored.. so.. I will spell it out differently: carp*kes dot com Rhymes with "car-smokes"

I used these guys when the factory boost gauge died in my instrument cluster.
They went through the entire unit, recapped the plastic board, replaced light bulbs, cleaned & inspected the cluster.
Less than a week and it was done.
Highly recommended.

Thanks for the replies everyone!
Update: So after I got my gauge cluster back in and turned the key - the boost gauge did't go to 1 - which is basically what it's been doing when it was working intermittently.
I took the car for a spin to see if it would start working after a while and as soon as I started moving I noticed that the speedo, fuel, and tach gauges were all non-functional as well as the turn signals and other dash lights so I suspected that I probably didn't get one or more of the connectors on properly. So last night I pulled it all apart again and found that the middle connector was not on tightly. Made sure all of the little black levers were all pushed to the middle fully and before putting the steering wheel back on I tried the key and low-and-behold the boost gauge made its way almost to 1 and all of the dash lights lit up as well. I still have yet to take it for a test drive since doing that, but it sure seems like my boost gauge may be feeling better now.

Glad to hear 👍. The connectors in the back can be a bit finicky. I had the temp. needle stop working once after removing the instrument cluster. Reconnecting it again solved the issue shrug 🤷♂️
