There is only *one*sure fire way to survive a crank with a load like a computer draws, and that is an auxillary isolated battery. Especially in a diesel where the glow plugs cycling draw a huge current. My vehicle has two (in parallel) batteries for cranking, and one for the electronics, the alternator charges all three, but the 3rd battery is isolated from the others. The cranking batteries are deep cycle Optima yellow tops, and the electronics battery is an Optima red top.
