should a battery lose charge if it sits for 2 weeks.when going at 2-3000 revs nothing on the voltmeter(reading around 12).at 5000 revs meter creeps up to 13-13.5-is this normal for the meter to not move until 5000 revs.

The T350 does not have a voltage regulator so you should not use a modern sealed battery. Conventional batteries loose their charge fairly quickly.
The alternator output specs are on page 17 of this manual:

The specs are for a good battery that’s charged up — the alternator should begin charging the battery by 2k rpm.
A charging system that’s OK + a problematic battery could produce the results you got.
Fully charge the battery, let it sit overnight, and then check the battery unloaded voltage.
