After taking about a week off from working on the KC, I'm back at it, I hope I can make some progress with this refurbish, it was going all good in the begining but then, I been finding a few things that are in need of fixing ( temp prob, retract valve, rudder servo working erratically and so on )

I now have one of the new jetronics valves with fail safe build in for the gear, I'll give that a chance to change my mind about these valves, I also have a new temp prob, that fortunally and unfortunately I won't be using, last night I swapped the probs and got the same error massage ( --E-- ) then now I knew that the cable and prob are good soooo, I swapped the probs again, then I started pushing and pulling around the comm Jack on the the turbine, next thing I know I was getting temp info on the GSU, I finally figure out that the cable is loose on the turbine's comm Jack, well, that problem, mystery is solved, the fix it's easy, I will be able to run the engine by Friday
