| RE: MSD 6AL always hot? |

I would be hot to the touch while triggering. That is the normal condition and why MSD (and other CD manufacturers) say to put it in a place where it can be cooled by circulating air.
As far as it being electrically hot, yes there as well. The capacitor stores electrical energy and releases it when grounded. The correct wiring method is to wire the hot lead to a constant voltage source, like the battery positive. You can discharge the capacitor and cause a spark without the engine running anytime you trigger the collapse of the field. Now, normally you would need to have voltage to the coil to cause a continuous trigger such as when using a remote starter when running the valves so if that's whats happening, check the secondary wiring to your coil to ensure that your bumping the engine with the ingition off shows no voltage to the coil + terminal.
When you think about it, even though the "box" is always electrically hot, without a trigger for the capacitor charge/discharge, it becomes inert. If your box continuously fires without the ignition key being on, then you've got something going on with your wiring which seems a little unlikely since the car would continue to run with the key off. |
