I have tried two different new trail tech vapors on my Sachsaha and they both blank out after a short while and reset repeatedly.  I have called their tech line and tried all their recommendations to no avail.  The tech said that it appears that I have been unlucky enough to get two bad ones in a row.  Should I really try for a third?  Any other suggestions?   Is there a better combination gage out there I should consider?  Anyone else run into this?  Any fixes?

Thanks
Jonathan
