My 7AL-3 is makes a high pitch noise when I turn on the key. It's been working fine for several years, but now it's making the noise. It this an internal or external problem, i.e. bad ground, voltage, etc? I don't see the green or red light on.

Thanks,

From your discription, it sounds like the unit is continuously firing. Check that your magnetic pickup wires (Violet/Green) are not run along side the spark plug wires. If they are move them away and try it again. Also make sure they are twisted around each other all the way to the 7AL-2.

MSD Tech1,

I replaced the 7AL-3 with another one and the noise went away. How do I get the bad one repaired?

Thanks,
