02 ford ambulance prep-package....dual alternators... secondary alternator controlled by pcm...there is about a 5 to 8 second delay before secondary alternator turns on. and food for thought....electrical load for the box with halogen lamps....at least 140amps if min kkk-1822e specs for an ambulance.
and on for seconds....liability, liability, liability....well, actually this would be my first thought
