smokeater75 Report post Posted December 24, 2014 Good morning and Merry Christmas to everyone. My dash boost gauge stopped working. The turbo is working fine, I can still see my boost pressure on the computer screen. Any ideas, if I have to replace it what am I looking at. Thanks smokeater75. Sorry about that its a 2003 Monaco Windsor ISL 8.8 Mechanical Gauge.RR 8 chassis Share this post Link to post Share on other sites
wolfe10 Report post Posted December 24, 2014 What chassis? Mechanical or electronic gauge? Share this post Link to post Share on other sites
Walt2137 Report post Posted December 24, 2014 Brett its mechanical, Check the little 1/4 inch plastic line should be black it can get against the exhaust manifold and burn a hole or come loose. Share this post Link to post Share on other sites
wolfe10 Report post Posted December 24, 2014 Yes, if mechanical, check carefully in the engine room first. A leak will leak boost as well as render the gauge inoperative. You could also take loose the hose at the engine and pressurize it to 20 PSI and verify that the cause is reading accurately. Share this post Link to post Share on other sites
