First test-
1. Main Batt Switch OFF to disconnect power.
2. Wait 60 seconds.
3. Main Batt Switch ON and observe Dash display. It should light up with a couple of numbers for 10 -15 seconds then go out.
Confirm - Yes/No?

That’s probably fine. Ignore that for now.
But the display went dark?
Next Q- Is this a new car to you?
Do you know when the last time is was running?

Lets see if we can ramp this up and shotgun a few Q’s in a row.
Have you done anything else during this battery swap? Specifically related to the charger?
Which charger is in this car?
Do you know if this car has the DC Converter/Wiring upgrade?

Ok. FYI
It looks like you have an old Schott charger
Yes- You have the wiring update
And a T1 Controller.
See this thing? This is your ACC Relay/Timer.
Look for 12v on the Org/Gray wire. (Confirm → Y/N?)
(Reference Frame Gnd)
If Yes-
You should also find 12v on the Green wire when you switch the KeyON (Confirm → Y/N?)
(Reference Frame Gnd)
Also - post one more pic of the same area including the item to the right next to the one I posted

Also - Check this wire. (red arrow on left)
It looks like the Key Wire Return.
Make sure it is pushed together better than it is.

You need to be more clear as to what wire you are testing.
I can guess, but if I guess wrong then we will just be going in circles.
To be More specific-
Green wire indicated in my first pic will be 0v when KeyOFF, and show 12v When KeyON.
(Confirm Y/N?)
