Hi
I'm fitting an EFIS D-100 in an RV-9A (not yet complete).
I've just wired up my D-100 & powered it up connected to the EDC and OAT probe for the first time. I'm having a little trouble with the OAT.
The unit finds the EDC and shows a roughly correct heading. The heading swings when I hold a lump of steel near the EDC so that seems to work. If the unit is set to a type 1 OAT it fails to find the OAT. If set to a type 2 then it displays 57 C. Its pretty cold here in the UK at the moment (around 2C). When I warm the OAT the temp rises to 59C, then shows OAT not found or something, but the unit will find the OAT a while later on a restart (back at 57C again). It was getting late, cold & dark in the hangar by that time, so I came home.
I checked the wiring connection of the OAT to the EDC.
I'm also not really sure about whether I have a type 1 or 2 probe, as I have a "magic marker" band about 1" from the OAT, not a 1" piece of heatshrink you mention elsewhere in this forum....
Any suggestions
Thanks
Dave
