James - At the very least, you could put a voltmeter on the battery to see
if the alternator is charging. If you see about 14 volts, then the
alternator is basically good. Maybe there is a bad isolation diode that is
allowing a backfeed current which is discharging the battery. A battery
disconnect switch should take care of that.

Subject: [6pack] Alternator: Moss or TRF...or other

Suggestions for a 1976 TR6 alternator.I do not want to do any mods to
brackets, etc (at this time), i need an easy swap for a new
alternator.Anyone prefer one over another? My alternator 'tested' out ok,
but i still have a red warninglight lite from time to time (most of the time
actually). The car is still in another state - so I only visit it (and my
family)once and a while. I don't have time to do a complete trouble shoot,
but suspect the alternator is going out. (it is original alt. - to the best
of my knowledge...or at least the same one since somewhere prior to 1992
when i bought the car) Not sure if the Coil would cause the red warning
light? (just thinking of anything in the circuit that may be outside
alt/battery)But Dan Masters book points to battery or alternator.Battery is
new...although it goes dead after sitting for a while...maybe i have a
drain/ground problem that is causing thedrain and maybe even the red warning
light. ugh. although i hate the 'replace and see' method, i don't have time
currently in my life to trouble shoot.
thanks!
james
