Factory Tach and boost gauge problem

Wright 63

Just getting back into the TR scene. Been out for about 10 yrs but couldnt stand it anymore :) I bought a 87 TR thats been wrecked and sitting for 7 yrs. but only had 57k on it. Car started and ran perfectly after oil and gas (filter) change but the factory tach and boost gauges are showing WFO all the time. The lights wont go down to a normal reading. I'm not going to use them anyway but it sure is annoying. Electrical tape over the gauges would fix the annoying part but I'd rather fix the problem. (Im sure this is the first of MANY problems I'm going to run into) I ran a search on here but couldnt find any info. Any help is greatly appreciated!
