Digital Dash Trip odometer memory

[STF420@comcast.]

I have a 1986 GN w/Digital dash.
The odometer resets to 3570 every time the car is restarted? I can reset it and it works fine until you turn the car off and restart 3570 again? is there a separate hot all the time wire that may be disconnected?
the trip reset & Mph/Kph switch seems to be working fine. Just does not keep trip memory while key is off.

TIA

Thanks, Mike

Mine did the same thing. I think it was connected to the cigarette lighter fuse

I will check that out.
I thought my cig light was working. But somebody also butchered an aftermarket radio install. It may have made the cut, or splice?

Thanks, Mike
