I am about to fit Ford EDIS (Electronic Distributorless Ignition
System) into my '87 E30 316 (M10 engine). While I was testing EDIS
something happened to the original ignition system.
I just disconnected HT leads from the distributor, and connected them
to the EDIS ignition coil. I started the engine , and let it run for
20 min or so.
Original ignition control unit (TCI) was connected, as was ignition
coil and pulse generator (in the distributor). I only disconnected HT
When I finished testing EDIS, I connected HT leads back - and the
engine would not start. I checked (ten times) that I connected HT leads
in right order (1-3-4-2 anticlockwise). I removed one HT lead and
connected it to a spare spark plug - and I had the spark.
I than connected EDIS back - the engine started immediately. Again back
to the original ignition system - now no spark at all.
So I checked if I had +12V and ground at ignition control unit - OK,
lead from it to ignition coil is OK, pulse generator resistance was OK,
only pulse generator gives 0.75V (should be 1-2 V). Perhaps I should
mention that it was -4 Celsius (-25F) when I measured this. Ignition
coil is ~0.8 ohm primary, and ~8kohm secondary.
I tried with spare ignition control unit - and it does not work.
Any thoughts about what might have cause pulse generator to fail (if it
failed)? Or did I miss something?
