As Elliot Moose told you the correct way to do it, here is a way to do it if you have a weak battery; no GPU. Get N1 spinning as fast as she’ll go, 10% maybe, with one paw on the condition lever bring it up to the detent but don’t allow it to set in. The RPM will rise, but so will the ITT, just as the needle is about to bust the red line cut the fuel, the ITT will drop faster then the RPM, when the ITT is down again introduce some more fuel and repeat the process as necessary. It kinda sounds like the engine is stuttering, vroom, vroooom, vroooooom, voooshhhh. You may momentarily exceed starter duty cycle, but if you’re out in the boonies at least you’ll be able to leave. Oh, just prior to shutdown close the inertial separators, they add to the ITT problem, and closing them without gen power zaps too much juice. You may want to practice this alternate start when your boss isn’t around, but it’s of a nice to know nature when you’re stuck out in the nature. I'm assuming you're on an ought two.
