Gents, I am upgrading my steam gauge panel on my RV9A with a 7" Sport ex and a GRT EIS, which I plan to mount on the panel above the radio stack as well.
I have the new sub panel cut and ready, and plan to install a switch from the power source to the Sport EFIS, so it can be off during engine start. I am wondering about the Engine information panel. (EIS 4000).
how did you guys do it?
Did you run both the EFIS and the EIS from the same switch?
Seperate them ?
Switch one and not the other?
The manual recommends a switch, but also I watched the videos and multiple power sources are also recommended, with the backup source being on all the time. Wont this defeat the purpose of having a switch on the primary power? Wont the EFIS power up from the backup wire during engine start when the master is on?
Another thing..I have tried to register on the GRT forums, and post questions there, but I cant get thru the registration page..it asks for the "registration code of the day" as the last question. I cant figure out where to get that. anybody know?
Thanks!
