Rev counter

[brainbug007]

After getting all the redundant wiring out of the loom and everything working except the lights and megajolt, it's just the rev counter I need to get working now. I've put the green wire from my edis into the right pin on instrument cluster (see attached picture) but when I run the engine the rev counter doesn't move I checked the voltage at the pin and with the key in position 2 and the engine off, it reads around 0.05v, with the engine running & idling, I get a reading around 0.35-0.39 (fluctuates). So would this mean the sierra instrument cluster handy andy gave me isn't compatible with an edis?

Thanks adrian, it did help a bit. I must say making the circut with diodes etc is a bit daunting as I've never made anything electrical before! If I have to go down that route, can I get stuff like that from maplins or ebay? I have no idea what to look for as the codes quoted don't mean anything to me I did come across this http://www.minifinity.com/forum/view...p?f=5&p=852579 which seems to indicate that pin 11 on the edis might work instead of pin 2 which I've already tried.

You will probably only get it to half read with the edis outputs, you can buy the diode thing already made from trigger wheels and run it from the coilpack which will definately work

Ah right so that's what those things are for on trigger wheels. So how do they connect to the coilpack?

You can also make it work from the alternator like the diesels do.

They have 2 wires going in and one coming out, the single wire goes to rev counter and the other two go to opposite sides of the coil pack

[brainbug007]

So do the wires just go onto the plug that connects the edis to the coilpack?
