Injector voltage

[fastback4]

1999 MC 3100 injectors. How much voltage is needed to bench test them to open and close......Tom

think of it this way: there is a fuse in the electrical center specifically for the injectors... and the PCM grounds them to activate them.

so, even though 5 volts would probably open them, it would do so much more slowly than they normally would.

so, shoot for somewhere between 12 and 14.4 volts.

^ Agreed. I use 12v/.5A because it's a preset in my supply at work.
