Charging system troubleshooting help needed

I posted 2-3 weeks ago about my 88 9kT 5sp that was not charging under load. The battery has been discharged quite often so it could very well play a part in all this. Anyways, here is what I know so far:
- Battery is 1 year old. Battery has been discharged 3-4 times. Once for 5 months.
- Car will maintain about 13V at idle with no electrical load measured at battery posts.
- Voltage keeps dropping as soon as lights + blower + brake lights are on. Drops to 10V before I shut it off.
- EDU screen has gone HAYWIRE in the last few days. Gibberish is being displayed. Sidenote: my dash is apart as I try to install some gauges.
- Battery signal lights up in cluster when ignition is switched on. Light goes off as soon as engine starts up.
- Resistance of +ve alternator connection to +ve battery connection ~0.5 ohm
- Length of voltage regulator brushed is 11mm.
