Right now the current state of my 92' 240 is as follows:
Some other details:
So now I'm just wondering if the issue is in the wiring from the ignition to the exciter wire, the ignition switch its self, or something else that I'm not even considering. Reading around it looks like this isn't a super uncommon issue except for the fact that in my case the exciter isn't getting the full 12v when the ignition is in position 2 (both connected and unconnected).
I'm also wondering if the issue I've had recently with power not making it from the ignition to the ECU is actually related to the exciter not getting full power. My gut says it is but I don't know enough to know if that's possible.
Any insight or help with this issue would be greatly appreciated!
- No warning lights (other than the overdrive arrow) when ignition is in position 2.
- None of the gauges in the instrument cluster are giving any reading.
- 12.4V coming from resting battery.
- About 10.5V coming from battery when under load (1500rpm, radio on, lights on.)
- 12v at alternator exciter wire when ignition is OFF.
- About 6V at the alternator exciter wire when ignition is in position 2.
- Same voltage (12V at OFF, ~6V at position 2) at the exciter wire when it's not connected to the alternator.

Some other details:
- The battery is brand new. Bought from the auto parts store this morning.
- The alternator is less than two years old.
- I have had trouble somewhat recently with power not going from the ignition to the ECU.
- The car starts up with no issue or hesitation.
- I have checked, cleaned, and re-secured the connections on the alternator and battery.
