In a previous post I mentioned how my Van was vandalised in mid engine
istallation. Part of the things they did was to challenge my repairing
skills by removing some connectors. Most I have repaired already, but, I
have a question; are the injectors solidstate (meaning polarity matters and
I have to trace back further), or wire (then I can just hook the wires up
not caring about polarity)? And if they are solidstate which lead is
positive? And, for future troubleshooting are they low active (always hot
and the controller provides a ground to activate the solinoid. Generally
used in solid state driver circuits), or high active (on side is always
grounded and the controller provides the power. Usally found in relay logic
circuits)?
