For those who have seen my recent posts you'll know that I took my recently acquired RV6A into a highly regarded avionics shop a couple weeks ago to have a Garmin G% installed (primarily) to gain an artificial horizon and do our bi-annual transponder check. Well after they moved the existing electronic/pulse tach to position the G5 - the tach stopped working. They ended up doing too much trouble shooting before just replacing the wire between the mag switch, tach and mag to get it working - and added $1,000 to my bill.
Yesterday, on our first flight since the 20 minute hop home on Thursday - the oil pressure gauge started fluctuating and dropping - which led to a quickly aborted flight. With some input from the mechanic who helped us with our recent annual condition inspection we replaced the wire to the oil pressure sensor and everything was fine on this morning's flight. BUT...
While climbing after T/O the tower told us our altitude was reporting very low. Turns out the Stratus transponder (which was working perfectly and had been recertified by the shop - is now reporting about 1500 feet low initially, then slowly creeps up within about 600 feet of actual (after 15 minutes) then lags greatly on our descent. OMG - talk about opening up a can of worms by installing the G5! (which by the way works beautifully).
The shop says they think they "may have missed a line of code" in the transponder - whatever that means - so for the time being we've turned off altitude reporting and are avoiding any Mode C airspace.
Anybody have similar experiences with shops or did we just have bad beginner's luck? Also any thoughts on how the transponder could be doing what it's doing?
