Please help us diagnose an interesting problem starting the plane. We have a RV-6A with an IO360. We run a two screen Garmin G3X, a VPX Pro, an Electroair EI and regular mag, and a one year old PC680 battery and a 3 hour Aux battery. The EI is wired directly to the main battery. We keep the battery plugged into the Odyssey charger/conditioner when it is on the ground. We have never had any difficulty starting the plane in the three years we have had the EI.
It was in the low 40s. Turning the AUX battery on (master still off) did nothing. Usually the PFD comes on line. With the master on and the EI and mag both turned on we attempted a normal cold start. The MFD went blank.
The starter turned fine but the engine would not fire. We turned the EI off and tried starting on the mag only. It started normally.
Once the engine was running we tested the Aux battery- it worked just fine when we shut off the Main battery. During the mag check it ran fine on the EI.
A few hours later on the return trip it did the same thing again. Both batteries read normal voltage on the VPX. Any thoughts?
