Julian,

Did it fail when you were getting to about 4000 rpm, ie does it work at all below that rpm level? Reason is that dependant on what type of tacho you have they either work at all rpm or at low rpm only! The differences in them is whether they are volt driven or amp driven. I had to change my tacho to the other sort but being so long ago I can't remember which way round it was and is now. I have a standard GTD tacho and same MSD 6AL but I do not beleive I have a tacho converter.

Not a lot of help but all I can give. Paul Thompson is the electrical wizard so you could try him.
