My 89 260e reads 14+ at idle, 13+ engine off.
Shouldn't it be 12+ for both? Case of voltage regulator?
Thanks

yes.2 screws.
idle:around 14 with daytime running light in Canada.14 is normal.
engine off:12.5 with alarm on and flashing red light(warning to would be carthief).you have to wait a while with engine off to drain off surface current(same after using charger or alternator charger),I am told.Immediately after shutting engine,my car read 12.85 or so.
