MSD 6-AL spark test - scary results !

Thank you all for your input & suggestions. My new digital 6AL is installed & fully operational. I would have liked to send the old unit back to MSD for repair but shipping costs & import duties add a lot to the repair costs so it was cheaper to source a new unit here in the UK.

The digital version offers some improvements, including a single block connector which makes it much easier to disconnect when working on the cars electrics. Also the rev limit can be indicated on the rev counter, which is a nice touch.

Kind regards
Hi Julian,

Out of interest where did you end up purchasing your 6AL from.


Hi Nick,

I got lucky, I found a private sale nearby. It had been fitted but never used. There are a few in the UK on Ebay if you're looking for one.

Kind regards
