Gremlins galore

 Nose gear high resistance connection. Found a bare ground splice under a wiring label in the wiring harness.

Capacitive fuel tank levels.   Reading high.  Corrected by tightening ring terminal screws on hell hole ground strip.

Hall Effect amp sensor occasionally reading negative instead of positive.  Cross checked with the VPX. -Update - seems to be working after tightening ring terminal screws. 

High fuel pressure.  Reseated the connector at the sensor and treated with LPS1 (electrical contact lubricant).

Flat nose tire.  Tire balancing beads had gotten in the valve stem seal when I checked pressure.  Cleaned out with a Q-tip and is holding now.

Red X's on CHT's & EGT's -  Remedied by tightening the ground on the engine.  The jam nut and nut were tight, but retightened and issue cleared.

#2 Spark Plug cap fell off-came unscrewed.  Fell out of bottom cowl when it was removed. -Update - replaced the plugs with solid top plugs.

SDS programmer display  backlight is working, but there's no text displaying.  Update-Barry is sending a new board. Update - board was replaced and is working again.

30 Amp fuse to distribute power for the Landing Gear, B Fuel pump and B coil replaced with a hard wire (each downstream circuit has its own circuit breaker.

Shorted PFD  - RMA'ed to Dynon.   Swapped left/right screens and trouble followed. ETR two weeks. -Update - Panel was returned and functions normally except for the temp widgets intermittently showing X's.  Update - retightened engine ground cable and the red X's cleared.

Pilot relief tube - needs more suck.  Testing with water, didn't draw out.  Need a tube moved into the slip stream to create a vacuum.  Update - tube has been extended.

Nose/leg area - still has a slight draft in flight.  Needs more sealing around the nose gear motor cover.

A quick test flight:
