Test at battery with engine running, should read 13-14.5 volts
Check connections, I usually clean them with some sort of acid neutralizer, then a battery terminal brush, and then finish up with my knife. Often there will be a hard layer built up that the brush will not get thru. Be careful tho, take too much off and you will end up with a terminal that has to be replaced.
Test battery or swap. In my opinion battery quality at most levels/brands has suffered. We have had 3 batteries in the last year or so that would randomly go dead, even tho we had used them the day before. After testing alternator, connections, and yes, the battery, several times, we ended up replacing the battery, and so far each vehicle/machine has not had anymore problems.
