Ernest,

loads are:
one HP fuel pump
EC2
4 fuel injectors
4 GM ignition coils
engine monitoring system
data logging system
2 GPS units
Com radio on receive, not transmit
intercom
2 axis autopilot
strobe lights
Dynon D10A EFIS
Hobbs

There may be others I didn't list.
I use an OEM RX7 Mitsubishi alternator and a standby ND alternator that is normally just a v-belt idler.

Steve, what other loads are you running.  I'm using the stock injectors, which are high impedance.  My generator is
rated for 36A.  Keeping the total normal draw below 29A max load was my target.
