RE: Relay panel shot?



12V to the coil should be safe...the Bentley and Haynes manuals both say to
disconnect the ICU connector, turn on the ignition, and see if you get 12V
across pins 2 and 4.  That's where I got 6.4V.  Since the ICU gets power
from the coil, that tells me I should have 12V at the coil as well.
