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. |
