Rechecked the wiring. I have a 0,05v drop from battery voltage on the positive to the coils, so that is ok. I have a 0,3 ohm resistance in the coil triggers between EDIS and the coils. So that is ok. I wired the coils directly to battery earth, thinking maybe a bad earth. Nothing, na-da, zip... no spark from Megajolt system, starts and runs well on Dizzy. I can still see the rpm's in the software. I guess I have to import a replacement EDIS 8?

Thanks. How does one go about monitoring the firing of the coils with basic equipment(no scope)? I have power on the coils. How do I see if the EDIS is telling the coils to fire? With a test lamp to a known earth I get 'light' off all three pins. Will run through everything again tomorrow. Good to known that the EDIS is normally not the cause.

Hi All, I installed megajolt a few months back and have been running a good few hundred kilometers with it already. Over the holidays I was in the mountains doing some rather wet mountain exploring in the Eastern Cape (South Africa). The 3.9i Range Rover went well all day, parked that night but would not start the next morning. No spark. Fortunately I still had the dizzy and coils so I went back to that for the rest of the trip. Getting home after my 4000km trip ) of which only 1000kms were with the megajolt, I have started looking for the fault. If I run the system in tandem I still have no spark although I can see the revs in the megajolt software so the VR sensor seems to be working. That was my first thought. I have power on the coils and on the EDIS 8 module, obviously also on the megajolt unit. Still no spark. All wiring seems sound. How realistic is it that the EDIS 8 module is buggered? They are scarce here in ZA so not so easy to swap out just for the hell of it? Any ideas?
