Ok I am checking my BAC so I pulled it off and left it plugged in to see if I heard the vibration which I didnt if I left it in its normal position as it would attach to the engine but if I rotated it 90 degrees so the hole is facing up it vibrates like crazy. Does this mean its bad or what??

 

Either one or both contacts inside the elec plug are *pushed back* a bit and not making contact with the contacts inside the BAC...............or the plug isn't on the BAC good. One or the other.

So hold the plug in your hand while looking into it. Then pull on the two wires in the plug to see if they move towards the direction your pulling. I'm saying one or both contacts inside the elect plug are not *locked in* the plug. Causing intermittent connection with the contacts inside the BAC.

 

thanks I'll try that!

 

Kind of off-topic, but is there a proper way to fix this, other than jamming something sticky in there? One of the wires to my leading coil does this.
