12H-T 24 to 12 volt conversion

Apart from the starter and alternator, does anyone know of any hassles putting the donk into a 12 volt vehicle?, such as sensors, manifold air heater etc?. Someone suggested the 24 volt imports have a 12 volt transformer for all accesories except for the starter, alternator and globes but I'm not yet convinced. Thanks.

are you converting a motor or a vehicle? to convert the motor pretty much all you need to change is the starter and the regulator (the alternator will make 12V with a 12V regulator, but the current capacity might be a bit ordinary). throw the glow screen away (do 12H-T have a screen or plugs?) either way it is more for emissions and less for actual starting - direct injection motors will start in subzero conditions with no glow.

12HT has screen

all the engine management will need to be sourced too

ie the glow system (if you thrpow awayu screen can throw this to) the EDIC controller. YOu should be able to use alot of the sensors directly of a 2H.

does 12H-T use EDIC or does it have a air shutoff butterfly 13B-T style?

good point, i just assumed an edic since the 2H used one.

Some googleing indicates they use some sort of a solenoid with a air shutoff as you suggest. If this is the case then converting a 12HT to a 12v should be pretty easy. A donor 2H would still come in handy i think. (for LOOM and sensors, altenator etc etc)

The motor is going in a different car. Not sure which one yet. I have plenty of 2H stuff lukily. If I can do without the manifold heat it will make life easier.

12HT has an air shutoff butterfly which is vacuum operated.
