 Let's connect the battery: switch on the battery switch. A few indicators should light on, but not all of them. Any way, with the battery connected you can start the APU.
-The APU start/stop switch is located near the throttle on the left console. Switch it on. Now look at the APU's RPM and EGT on the engines guauges panel. If the APU started successfuly you should see the EGT (Exhaust Gaz Temperature) climb very fast until 800/900°C and then stabilize while the RPM reach 60%/

+Now the APU as enough RPM to provide electrical power trough its generator. So let's turn on the APU generator. This one is on the main electrical control panel, upper left corner of the electrical control panel, right console again.
+With the APU generator on mostly all instruments receive electrical power and now the HSI (the compas) and the ADI (artificial horizon) should look much better.
+At 85% RPM the APU supplies enough bleed air for starting the engines.
