ScanGauge-II not restarting w/out alt

my scangauge doesn't restart when I do P&G cycles & I don't have my alternator belt. :confused:
what can I do ?

Is it set to hybrid mode? (not gasoline)

yes and my scangauge is just like that when I drive with no alt
with the alt it is normal

If you upgrade the SG's software you might be able to keep it from turning off during EOC:

Good news!
It appears that updating the ScanGauge's firmware gives a new option to keep it on during EOC. You can now keep your fuel type (no switching to 'Hybrid', unless that is your case). Here is what to do:
From the start screen press MORE, then cycle through the options until ADV SETTINGS, enter EDIT and cycle to SLEEP EVENT. By default this is set to 0 RPM, so the SGII shuts off when the engine stops. But if set to NO COM, then the ScanGauge should stay on during EOC. NO COM is default when in Hybrid fuel mode.
Warning: This may cause your ECU and SGII to stay on and drain the battery. Make sure that they turn off properly when you key off and leave the vehicle.

My SGII was recently upgraded (ver. 4.0.1 iirc) and I found this new option. It appears to work just fine, even though I have a diesel:D
+1 for LL:thumbup:

EDIT: In my SGII the SLEEP EVENT has a third option: VOLT. I can't find any info on this option, the SG manual only mentions 0 RPM and NO COM. Maybe it is for electric vehicles?

My car has been alt deleted since March 2011.

Check your "current trip" timeout setting. It can be adjusted, probably up to 99 minutes if you wanted. If your EOC is longer than the timeout the SG display will go off. One press of the "Home" button in bottom right corner will start it up when needed.

The SG is designed to come on when it detects the voltage increase when the alternator comes to life. Without an alt you can always wake it up with the home button.
