Shortly after starting the Number 2 Engine we had a large amp draw. Battery feeder fail master warning occurred and we promptly shut down both engines. Cabin door was opened and line guy said he saw smoke coming from our tail section. We evacuated the cabin and nobody was injured. Fire was electrical in nature due to Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) box failure and was contained mostly internal aft of the baggage compartment; however visible fire damage to the deice boot section of the right elevator. I was made aware after the incident (by the mechanics at the repair station) that an optional service bulletin was available and not complied with by choice of the owner. Apparently there have been a few fires on type because of this exact component failure.
The reporter stated that about 15 seconds after engine start they received a feeder fault and that the load meter for Number 2 generator went to the max indication. The generator tripped off line as a result of the excessive load. The reporter also stated that the cause of the smoke was the power supply for the stabilizer deicing boot shorted out causing a fire in the tail section of the fuselage. The reporter stated that this box should not be powered during ground operations; only in flight when deicing is required. The reporter stated that the fire changed the color of the metal surrounding the area of the fire. The reporter also stated that if this happens in flight the only option is to pull the control breaker for that system. The reporter also stated this option does not put the fire out; only removes power from that component.The reported stated that this has happened at least four times on other BE400s. The reporter stated that there is an optional Serviceable Bulletin for this problem; but there are no replacement parts available.
BE-400 Captain reported that they received a 'Battery feeder fail' master warning due to an electrical fire in the tail section.
