Thread: MSD 6AL won't disable rev limiter mode.

  1. #1

    Default MSD 6AL won't disable rev limiter mode.

    Hi. I've tried several times to disable my 6AL Digital rev limit mode. I set both dials to "1" and then ground the tach wire while turning the ignition from off to on. I remove the ground on the tach wire after 5-7 seconds. Then I cycle the ignition from on to off and with the tach wire ungrounded still show the full tach sweep. The red light is on constantly no matter what mode of operation, except of course when power is off. I need the rev limit removed for my Atomic EFI. What am I doing wrong? Or is the 6AL failed?
