Superformance Electrical Problem with shutting of Engine

[ha_pe_1968]

Hi!

Please help me, i am in need of an advice:
Changed my Holley Carburator to a Quickfuel without choke. Was disconnection the cable from the choke and what a surprise: was not able to shut of the engine. My inginition is a MSD 6AL on a Roush427R. So it seems the ignition box needs an application as a Resistor to shut of the engine.

Was trying to take the wire from the choke to a 12V 4Watts bulb and everything was ok - was able to shut of the engine again. Of course it makes no sense to have a lightbulb in the engine compartment which is allways on - so i am searching for a solution.

It could be a solution to replace the lightbulb with a resistor. Calculating says 12 Volt 4 Watt should be equal with a resistor at about 28 Ohms. When i measure the bulb my multimeter tell me 5 Ohm. Seems i am not an electrical guru :-(
When i find the right resistor it should work again and i can take the resistor at a hidden area. The disadvantage from this solution is that the resistor allways will pruduce heat when the engine is on.

Second solution could be to take the resistor between the red light on the dasboard (alternator) but i have not tried it till now. This will have the advantage that the resistor only produces heat when the red light is on.

Can someone help me with more electrical experience or is there another easy fix for this problem?

Thanks a lot
Peter
