Hi Chris,

Per your lamp report, it is certain you are fighting more than one problem. Once you get your wiring diagram, you'll see the path for testing the lamps (that's what lighting them key on engine stalled is for) includes the alternator for four lamps: Battery lamp, parking brake lamp, brake failure lamp, and bulb failure lamp. This is necessary, because with the exception of the battery lamp, those other three, and the service lamp, cannot light without their warning conditions being met. There are four diodes on the instrument cluster allowing this to happen before the alternator begins to charge.

So, number one, your alternator and its ground are suspect, and the result is the battery is not getting charged. Why the alternator lamp was not lighted is a problem in the cluster which could be as minor as the filament in that bulb is broken.

But, number two, the motor not starting could be related to why you don't get the check engine or SRS lamps to light. These two need power from the ignition switch and from the 25A fuse on the fender to supply the fuel injection and ignition computers from the latter and the SRS module from the former. A trouble common to both could exist in the wiring at the junction box on the left fender (by the blade fuse) or the ignition switch itself. Phil's suggestion to start with power supply is right on, but I understand it is some difficult thing to do without the maps. Although not as nicely done as the factory maps, have a look at this 1990 wiring diagram while you wait for the real thing.

Important question: Is this car new to you? Have you recently done any work near the cluster? Has the ignition switch (electrical portion) been changed yet?
