Working on a buddys vehicle tonight. Truck starts with a boost, then will only run a couple of blocks and then dies. I checked the battery with my volt/ohm meter while engine running and it was registering 9.7 volts, and it continually dropped down in voltage on the meter while the engine was running. After we shut off the engine, I checked voltage at the battery again and it was 10 volts even and held there. I suggest his alternator is bad as it is not charging the battery, and it is drawing off of the battery when running. Is this correct?
