I think Bob has some data concerning just how many amps of current flow is required to excite an alternator, buttttttttt I can tell ya one thing till him or Jim arrives, an LED may be??? wayyyyyy toooooooo high in resistance (i.e. it dont allow sufficient current flow to excite the alternator) and thats why a regular lower resistance incandescent bulb is used in an alternators excitation circuit. Some use a diode there but I prefer at least a 10 ohm resistor to limit current and a small incandescent bulb limits current even further buttttttttttttt Im afraid an LED is simply too high in resistance such that theres NOT ENOUGH current flow.....
Im sure Bob M or Jim can give you more exact specs or resistance or current values but if she fails to excite using an LED you may have to switch to a small incandescent indicator light.
It dont take much current to make an LED glow, maybe thats why it stays lit buttttttt still if its wired off the Ignition switches IGN terminal or the coils input there shouldnt be any voltage present with the switch off so it shouldnt glow regardless IFFFFFFFF all is wired correct and the alternator is okay
