we tried to shark his car last night, after reading the instructions and all about how it says to keep the power supply a minimum of 12.5v for the entire process or risk screwing up the car, we didn't have a battery charger, so we tried hooking his batery up with jumpers to another battery.
we checked the battery with a VOM, read at 12.53v
it ran the backup process fine, but the gave us an error code for not enough engine voltage.
checked the battery again with the VOM, still 12.53v.
should we just go get the charger and do it like the instructions say, or did we just miss something?
