The cold start valves are battery voltage devices. The air cooled injectors
are current operated devices. 3 ohms at 12 volts = 4 amps. They will burn
out fairly quick if left energized. The water cooled injectors are ~ 16 ohms
so they draw .75 amp.

they'll be all right operating them on 12 volts for bench testing.
or at least, I can say I have operated hundreds of injectors and cold start
valves on 12 volts and never hurt one.
