Alternator issues
not sure if this is the right place for it. (and i have tried to use the search function)
I have a '68 with a bosch altenator attached, and recently while putting a new speedo and external idiot lights in it i realised that...despite the
fact that the idiot light acts normally it is not charging 
any ideas?
the idiot light is an LED, but i had to add resistance behind it to get it to switch at all. and that seemed fine.....but if i then pull the battery
terminal the car will just die

The alternator uses the current through the warning light to excite the fields(?). So if your warning light is blown the alternator will not work. The
LED probably is not suppling the necessary current or none at all.

Try temporarily fitting a normal bulb and test with a voltmeter, if you see 13+ volts, (pref 14.2-6 with a charged battery)
