Read no start guides and printed out etms for ground and power for dme pins and c101
I have ‘88 e30 m20 late model w/ 1.3 motronic. No light for dme. Made sure the light wasn’t out by checking voltage at coil with ignition on. No voltage so definitely towards dme. To start off I don’t get power from the inline fuse so it’s bypassed with a wire from the big wire on the junction block back to the wire. Made sure there is power there too.
Dme relay has battery voltage but not clicking when connected. Verified relay works by checking it with power probe.
I forgot which pins on dme but there is one that is a hot wire constant voltage and it had battery voltage. Verified w/ power probe and circuit tester. The other two pins had no switched power with ign on.
I’ve tried 2 separate dme’s & harness’.
Always have noticed on c101 pin 7 does not have any voltage. I still have to check the obc relay & pin 27 dme which gets power from the obc relay but figured give it a shot here and put the flame suit on if I’m overlooking something.
