1989 Dynasty 3.0L:
The ASD correctly receives 12v from both the signal switching source ( double white wire 12v supply from ignition key) and the constant 12v battery source ( double grey 12v from battery wires). See photo.
The ASD does correctly send power out of slave terminal green wire to the ignition coil positive (+) when slave circuit is triggered by ASD's internal primary circuit coil.
All good.

But, ... the ignition coil (+) terminal fails to light up my 12v test light that has probe at ignition coil positive terminal and other end gets grounded @ battery negative post.
I have not disconnected the green wire that should deliver power to the positive coil to test it separately , Do that tomorrow , better weather.
Perhaps this must be done to isolate why 12v is not sparking the coil.

Where does the green wire go after it leaves the ASD relay?
Perhaps a connection is corroded or green wire 12v is shorting ?


ASD Relay: white is 12v from ignition key switch, grey is 12v from constant battery positive supply, green will correctly send out 12v when commanded , blue/pink is ground for signal switch . All appears to work correctly.
