moerex Posted March 14, 2007 Share Posted March 14, 2007 hello all. i'm trying to run an edis setup on a ms v3 with relay board. the edis is not spaking as it should. i have checked and rechecked my wiring it is just like this how do you test the module, coil packs, and the vr sensor.

Administrators BRAAP Posted March 15, 2007 Administrators Share Posted March 15, 2007 Ok. I was fortunate in that my EDIS-6 worked flawlessly from the get go, (other than my lack of verifying resistor spark plugs and using MS friendly plug wires on the out set). 1) Is it sparking at all? 2) If it is sparking, I am assuming that your engine does at least run, other than on the starter? 3) If it is sparking and running, is the timing stagnant, i.e. at the preset 10 Degrees BTDC?

z-ya Posted March 15, 2007 Share Posted March 15, 2007 From a post I made last year: OK, got it running today on EDIS. Only encountered one problem, the way they label the coil outputs on the module is not correct for the L6. I ASSumed, that coil output A would go to 1st and opposed, B would go to 2nd and opposed, and C would go to 3rd and opposed. NOT! Hear is the wiring diagram: They should be connected like this: Coil output A (pin 10) => 1st and opposed Coil output B (pin 12) => 3rd and opposed Coil output C (pin 11) => 2nd and opposed Everything else checked out OK on the EDIS MS FAQ Quote Link to comment Share on other sites More sharing options...
moerex Posted March 16, 2007 Author Share Posted March 16, 2007 No. There is no spark at all at any time. Quote Link to comment Share on other sites More sharing options...
z-ya Posted March 16, 2007 Share Posted March 16, 2007 Try swapping the VR sensor leads. If they are wired opposite, nothing will work. Quote Link to comment Share on other sites More sharing options...
moerex Posted March 16, 2007 Author Share Posted March 16, 2007 ok i'll try that in the morning. thanks alot. todd. Quote Link to comment Share on other sites More sharing options...
moerex Posted March 16, 2007 Author Share Posted March 16, 2007 Ok, I got up early this morning and swapped the lead to the vr sensor. and nothing changed. I did not use the sheild because the wire i got out off the salvage yard was to short. Would that be the cause?? Anyway I'm gonna check some things with a multimeter to make sure it is all getting power. Thaks for all the help guys Todd Quote Link to comment Share on other sites More sharing options...
z-ya Posted March 16, 2007 Share Posted March 16, 2007 Yes the shield is important. It should be tied to pin 7 at the EDIS module only. Do not connect it to chassis ground. Quote Link to comment Share on other sites More sharing options...
moerex Posted March 17, 2007 Author Share Posted March 17, 2007 Ok, that my be my problem. Would it be possible to make a sheilded cable. I only have about 3 inches of the original harness. I have some foil tape and some spare wire. Thanks again. Quote Link to comment Share on other sites More sharing options...
Clifton Posted March 17, 2007 Share Posted March 17, 2007 You should still be able to get a spark without sheilding. I would check power at the plugs. Make sure your have power while cranking, not just with the key on. Quote Link to comment Share on other sites More sharing options...
z-ya Posted March 17, 2007 Share Posted March 17, 2007 If there is enough noise on the VR signal, then the EDIS module will not fire the coil. The VR signal has a very low amplitude, so any noise that couples into it can have a big effect. Where you you have the power to the MS connected? It should be at the battery (not the starter for example). Quote Link to comment Share on other sites More sharing options...

The VR signal has a very low amplitude, so any noise that couples into it can have a big effect. Do you think he would have noise without anything running though? I don't know, just assuming there wouldn't be. I know there would be some if it was firing. Quote Link to comment Share on other sites More sharing options...
z-ya Posted March 17, 2007 Share Posted March 17, 2007 Just cranking the engine can cause noise. Noise from the starter motor can couple into a very low amplitude signal like the VR output. Quote Link to comment Share on other sites More sharing options...
moerex Posted March 18, 2007 Author Share Posted March 18, 2007 ok i moved the power to the batery. i'll check the power on the plugs in the morning. just got off work... Thanks alot. Quote Link to comment Share on other sites More sharing options...
moerex Posted March 22, 2007 Author Share Posted March 22, 2007 I GOT IT!!!!! new sheilded cable and some repositioning of the vr sensor and vawla. Thank you all for your help. todd Quote Link to comment Share on other sites More sharing options...
