My bottom line on the screen will flash "BATTERY VOLTAGE TOO LOW" at ~9 volts, IIRC. When I'm cranking it when it's too darn cold to start, I can hear it trying to fire but as soon as the voltage drops far enough that the warning appears, it will no longer try to fire. Then out come the jumper cables :-( When Tracy finishes vacationing or building Rusty's parts or trouble shooting for John or Bernie, maybe he'll come back to us lost souls and clarify this for us. Cheers... Todd. So, given that "data point", looks like it might be useful for us folks with "computer dependent" engines, which need 9v (for this particular ECU), to fabricate a second LVM (set for 9.1 or 9.3 v) that turns on a light - or voice warning - to tell us "voltage too low to start" (i.e., below ECU minimum voltage required to start). I'd probably put the light close to the starter switch.
