Wired Alternator to Master; Fuel Pump
Tonight I started wiring up the alternator. The Plane Power alternator actually comes with a harness. I wired it up to my master switch.
It's hard to tell if it's working because obviously my engine isn't running but when I open the charging circuit I see a .2 volt drop on the EMS. Good enough for me.
BTW: I'm not sure if I've mentioned this yet, but my master switch is a three-position switch. Bottom is off, middle is battery, top is battery+alternator. IMHO this is a great way to do this.
I also ran the alternator out indicator light to a location just above the EFIS. I'm probably going to install a warning lamp but I don't want anything that looks too cheesy. In my opinion a light telling me exactly when my alternator stops charging is a great thing. I'm actually wondering if it wouldn't be possible to wire this to one of the EMS GP inputs and have the EMS sound an audible alarm. Hmm....
OK...I also wired up my fuel pump. The little black things are the tie wraps that I cut off the wiring so I could run the fuel pump wires. This pump was one of the things that I forgot to wire. I also need to extend the EMS harness wires out to the wing roots for the OAT and fuel level sensors and wire the mags and starter switch. I'll probably do that this weekend.
I did flip the master on and off very quickly to verify that it worked.
