Hi DanEC. I think the ERA procedure recommends a 20 ohm resistor. My NOS Lucas RED indicator light (same as on original Cobras) had a fine wire "coiled" around it's base which acted as a resistor. My recollection is it measured 5 ohms. Maybe not enough to excite the alternator.
Into the garage tommorrow to trouble shoot.

Cheers
Greg
