im running edis 6 on my ms2 v3.57, and i dont seem to be getting any signal, wiring is exactly as shown on the diagram, i took a voltmeter to pin 24 as wel, it shows 12v, when i crank it drops, but stays 1 voltage, it should change voltage right?, could this be from sensor polarity, tho it is wired in as it would be when it came,, ,



could it be a bad edis box?

ok, this is wierd, the edis controller box is getting very hot when i plug it in,, i checked the wires and they're exactly like this

Is there any chance you have the module pins backwards? If not, it sounds like you have a dead module.

ya it was bad, i just got a new module. it shows rpm on the first crank only and rpm goes up to 136rpm then stops reading.

module isn't getting hot anymore either.,

you said r52 and r56 has no effect on this setup right?

If you get sparks and rpm for a short while and then it stops sparking and rpm
goes to zero, the good news is that all LV wiring is most probably right.

The reason the EDIS shuts down can be that the HT circuit is a bit off. Each plug wire and plug
should have a resistance of > 5000 ohms. If not , the EDIS self diagnostics is establishing
that there is an engine fault and shuts down.
I have checked this on both EDIS8 and EDIS6 modules in bench testing .
The EDIS 6 even has a pin, #4, on which you can scope the coil charging current!

Get hold of resistor plugs and/or resistor HT leads, make sure that each pair is >5 kOhms and then
I guess your troubles will be over.

BTW, I would be happy if you would sell me the faulty EDIS module( the one that got warm)
I live in Sweden. Is this possible?

well, thing is, before i was adjusting pot meters r52 and r56 to get a better signal off my toyota distributor, and i adjusted them quite alot, i thought they would stop turning at some point but they keep going.. so how can i tell where i have to have them.

Not if set up according to the manual.

lol, it was just a backwards vr sensor, my mistake of color matching the wires from the harness to the vr sensor wires.. ,

original edis module was bad though, thing almost melted when i'd turn the key on. .
