Well it's better, but I'm still getting <1.5v 
When I bought all my bits, I got a mount from triggerwheels, but ignored it as it clashes with the mount for my repositioned alternator. However on
reflection I may be able to use it if I chop the thickness of the mount out of a tube in the alternator mount and move the trigger wheel to the rear
of the pulley lump.
If I wasn't so incompetent, it'd be boring

So much for that plan, I may be able to get the triggerwheels bracket in, but the sensor would not fit with the alternator in place.
Time for a rethink.

Still no joy
I made a new, more solid, simpler mount
And I get a good 1v RMS AC out of it at the connector to the EDIS module. Still no spark. Oh well, tomorrow I'll check to see if I'm
getting a signal to the coilpacks.
Anyone have a spare EDIS8 I can borrow?

I had a thought.
Are you connected to megatune or tuner studio.
Either way under cranking you should get an RPM reading on the guages. Is so your Vr is doing it's job if not it's where the problem is.
If it looks wrong it probably is wrong.

SPARKS!
Unfortunately I don't appear to have the RPM signal at the MS that I did in my first post.... Getting closer though Thanks for all the
suggestions so far.

Nice work, looks like you are getting pretty close.
I guess you need to see if you are getting the "pip" output from the EDIS into the MS unit.

But I guess you know that already! Outside my experience unfortunately.

I'm beginning to suspect my MS as I'm seeing a respectable signal on the PIP line (as respectable as it can be with only a multimeter
anyway). I'm going to open it up tonight to see if anything has obviously let out the magic smoke.

Another random thought - how have you earthed the screening on the VR sensor's cable?
It should only be earthed at one end, to avoid 'hum loops' - if it's earthed at both ends then the screening picks up interference,
which it then radiates to the signal wires inside. If it's earthed at one end only then the loops can't happen.
In fact, ideally all of the ignition system earths should be connected to one point.
Also - I couldn't see whether anyone asked this earlier - is your sensor polarity correct? A quick search on this site should result in a neat
diagram (I'm sure that came from Flak, but don't hold me to that).

Have you got a stimulator for the MS?
I borrowed one (thanks Lars) which was excellent.

I did originally borrow a stim from MakeEverything and proved my MS was working back in November. I had a word with Phil at ExtraEFI and he said try
rapidly switching the PIP line to ground to fake an RPM signal. Tried that and not a trace of a flicker. I've posted off my MS to him to have
a look at. Looking on the bright side, I've now got a working EDIS, so I could always slap my carbs back on (!)
I think in all my fiddling I've at some point connected something to something that I shouldn't. I couldn't see anything obviously
burnt out inside it, but if there is Phil will find it.
Regards,
Dave
