Question about 1989 Mitsubishi Sigma
9.3 is a really dead battery - replace it and check the alternator. I have seen them go bad with no dash indication. As to the oil being black, you may have worn piston rings, and probably need an engine re-build. Worn rings allow the exhaust of the engine contaminate the oil - you should also see increased oil consumption due to the vapors exiting via the PCV valve and being burned in the engine.

Has the clutch been replaced recently? There is an earth wire under one of the bell housing bolts,if not refitted can cause all sorts of problems.
