MSD Box Noise?
I have a MSD 6AL box and the other day when I was driving I heard what sounded like a quiet electric hum coming from the box. It almost sounded like a hum you would get with an electric fuel pump (I have a mechanical pump so that wasn't it;) ). I only hear it periodically and the car is running fine.
Is this normal? Has anyone else heard this? |
Chaplin,
Its normal. The coils and caps inside vibrate as magnetic fields are induced in them. If you listen closely you may even hear a tick each time it fires a plug. Drive faster so you don't hear it. :D |

Jims right--never noticed it on my other car but on this one I would hear it and it was driving me nuts thinking something was wrong. Then by accident I happened to hear it when I was under the hood and had the engine running at about 12-1500 rpm. |
Chaplin,
You can hear a little humm over the sidepipes? GEEEESH! I can't even hear my electric fan over mine.:D John |
Jim/Gary-
Thanks guys. Good to know nothing's wrong. John- I can't hear much over the pipes. **) The only reason I can hear it is because it is mounted inside the car under the dashboard. And I've only heard it a couple times. |
A noisy MSD box in a Cobra?
Turn the radio up a little more. TURK |
Turk,
I would but I don't drive the most accurately detailed 4000 to original specification since the demise of CSX 4027, and therefore, I do not have a radio. :p :LOL: |
Chaplin I belive there was a thread on this about a year ago can't find it but the offending member (MSD Box) was sent to factory and was replaced might call MSD I have had several and mine don't sound like my fuel pump.:)

Junket-
Just to be safe, I called MSD and they said that it is normal for the box to make a slight humming noise and that it is nothing to worry about. |
