Thank you for the feedback, Will.
One note to keep in mind to all; whenever the airplane comes out of annual or any wiring/panel related maintenance; make sure you test the Gear Warning System again, the best test is to do a low-approach with the gear up, then perform a go-around, the unit announces “Check Landing Gear” every 4 seconds until a positive rate of climb is registered, or the gear is extended.
We did get a report from a pilot who handed over his airplane for a GPS/EFIS upgrade, the shop temporarily removed part of the panel along with some wiring to assist with their installation and when they put it back together, they ended up connecting the GWS wire to a permanent +VE source; unaware of its functionality or why it was there in the first place; this effectively made the LHS unit sees the gear as always down.
He only found out about it when he wanted to demonstrate the GWS feature to another pilot, so we asked him to troubleshoot the location of the GWS wire after he told us the airplane just got a huge panel upgrade. Apparently; system failures and issues after maintenance is a hot topic at the moment.
It is a good idea to have an “After Maintenance checklist” with first flight to be around the pattern and check all critical systems such as the Gear Warning System, autopilots and such.
