The leads are from a Ford Crown Victoria. Of course, our engine only uses 6 of the 8 leads!
Problem is solved - it was a bad spark plug that only fired intermittently and then at lower intensity. Certainly not a common problem...

Our OHC jeep straight six with Megajolt light Junior EDIS suddenly developed a misfire (she seems to be running on 5 cylinders). There is a spark at all cylinders however. Clearly the sparkplug wires are old and need replacing anyway. I got the parts from Boost Engineering long ago but have the impr...

If you're asking if there is something wrong.... no. But I have another project (Healey 3000) that I'm considering and also like the idea if using the exact same parts in two cars... Interchangeability is always an advantage.

Yes, thanks... but I really need to get out into some rural wrecking yards. I want to find an EDIS6 and matching coil exactly the same as the one Boost Engineering sent me - good to have handy replacements.

Haven't found much on eBay yet.

Is there another business that offers the same service? I would like to pick up another set of used Ford EDIS parts.
Suggestions?

Thanks

Success! The Willys seems to be running properly again. MJ computer readouts seem to be working... It was a fuel starvation problem... squirted some ether down the carb and she sputtered back to life after a long crank... air in the line? water in gas? sticking float bowl valve? Thanks for the help ...

Yes, with the MJ disconnected, the engine shows no sign of life at all, very strange.... I'll check some more obvious possibles and report back.

Sure enough, when the various 12 Volt inputs were checked a bad connection on the upper side of the board was found while the under side still had a properly soldered joint. In the picture, I have shown exactly where the re-soldering was done. Power (green light) is on now, but the engine won't star...

Thank you Brent... I'll check the voltage where the molex pins are soldered into the printed board tomorrow.

With engine running, we connected up the computer.... program opened but nothing - no rpm, no vacuum etc shown and the little green LED light on the MJLJ unit is off. Checked the obvious power/ground connections and that the pins in the molex are seated properly - all OK. The soldered connections on...

kucza: two things come to mind... firstly, is your CPS aligned properly with the teeth on your trigger wheel. In the photo, it looks like the sensor could be moved outward to get better coverage. When I made my own wheel, I found that the strongest sensor pulses came with a specific alignment. Secon...

Thank you Brent:

Ours is an EDIS-6 coilpack but I'll just flip in a 15 amp fuse as you recommend and see what happens.

Cheers

OK, I found a thread on this topic back on Jul 08, 2009 9:58 pm. As I understand it, you measure the current flow with the system running and then use a fuse of a higher value. Sounds simple.

It would be interesting to see what fuses Ford used for these circuits. Does anyone know?

I installed fused power supplies for the coilpack, EDIS unit and the MJLJ but do not know what size fuses to use. At the moment I have inline fuses from the battery of 30 amps and 5 amps for the Ford components respectively and only 1 amp for the MJLJ. Am I way off base? Everything works well so far...

Final follow up... measured the timing last night (finally found my ancient Sun Timing gun) - it was about 11 - 12 degrees before top dead center. So I'll plug in -2 degrees in the trigger offset window - hope that is correct.

Once again thanks for the help
