The relay should be automatic. Ensure parking brakes on (v key) Turn on both batteries (to the on position), then turn on the battery temperature display, ensure its showing <56C for BOTH batteries (maybe the max is higher, cant remember off the top of my head). Set the volts/amps switch to right gen. Move the condition lever for #2 to start and feather, then move the start switch to #2, hold it for 2 seconds. -at this point the engine should catch and stabilise with the prop feathered after a few seconds. Turn on #2 generator by first moving thr switch to the RESET position, after ~3 seconds you should see the volts/amps meter showing a load. -allow the battery to charge for a few minutes (indicated by the amps load gradually dropping). When the battery temp drops below ~39-42C: -turn on avionics/inverters **(you can choose to wait until after #1 engine has started) Repeat start procedure above for engine one. After both engines have stabilised with gens on + avionics on, bring both props out of feather together, pausing at each point until the engines have stabilised before moving to another, until you get to the 'max' detent. --Xavier
