914world, please save me again from my mediocrity.

2316cc T4. I used to have an Empi distributor with Bosch blue coil. I upgraded to pertronix 45kv 0.3 ohm coil and pertronix distributor. Great spark now, easier starts, but my alt. light stays on. Previously, i would have to get rpm over 2500 to make light go off, now no spike in rpm will make the light go off.

I have led bulbs in dash, and i am willing to do the 100 ohm resistor mod to the alt light if that is necessary.

perhaps your voltage regulator is going bad.
Do you know how much power your alternator is producing?

Its weird that the light would stay on until you hit 2500 rpm.

I thought the ALT light needed to be incandescent (or resistor). Just pop an regular bulb in there and observe the changes if any.
