ITs an 85 xt turbo fwd... Anyways one of my coolant lines sprang a leak so i pulled the trubo out... I am replacing the rubber hose and all the copper washers... But before i pulled this sucker, my stock boost gauge only would either show it being at the very lowest or all the way up.. It would never stay inbetween.. SO do i have a problem with my wastegate?

 

What do i need to do to test me wastegate? it doesnt have any wire hooked up to the turbo itself, so how does my stock gauge on my digi dash even work?

The stock "gauge" on a digi dash is not one... It's similar to the other turbo light found on analog dash cars as it uses the same sensor. When you make about 1-2 psi boost, it gradually lights the segments until it is fully lit. If boost goes away it stops doing so. The segment timer circuit is built into the cluster itself. The end. Sorry, it's just a really fancy light.
