I dig it the most. I've been studying the wiring diagram most veraciously. All my measurements have been taken first with the key in RUN and then in START, just to be sure. I checked the ECU last night, but didn't really check that it was getting power. I did check that there was continuity on the white/slate wire from the ECU to the coil. So, my plan of action should be to check voltage at fuse 1, then check voltage at green wire on the ECU. What gets me is that this whole thing is such a simple circuit. What could I have done to create this problem? Where does the pickup coil come into play? Is this something to worry about AFTER the coil is energized? > -----Original Message----- > From: cruznmd [mailto:racuti1@xxxxxxxxxxxx] > Sent: Wednesday, August 27, 2003 10:55 AM > To: DMCForum@xxxxxxxxxxxxxxx > Subject: [DMCForum] Re: Electrical gremlin... no power at coil > > Brother Maynard, > > Consult the Book of DeLorean, Chapter M, verse 18:04: > > And the lord spake, saying thou ignition ECU shalt thou have power to > provide voltage on wire white/slate, provided thy most holy fuse #1. > > In other words, the module must have power to power the coil.
