I have an interesting one, which simultaneously drives me mad:
I checked the door light which (should I guess) come on with open doors. I accidentally touched both contacts with my multimeter and heard the fuse blowing immediately. No big deal I thought - but after changing to a new one (not sure if all fuses have the correct value because I ran out of fuses ) ) I got only 2 Volts!
One day later I drive the truck, an 1993 E350 Quigley 7.3 IDI:
> NO OD and harsh shifts, which is probably due to the same issue. and no Odometer and speedometer. :exclaim:
> What has the internal van circuit to do with the E4OD controlling?
> Why is the circuit not broken but still running 2 Volts? What reduces the missing power? A ground cable cannot be broken suddenly and due to a blown fuse.
> The OD issue has happend before, in early 2014. Since then the truck has been in garages until 5 weeks now! I have NO idea what the (very bad mechanics) did to the car. Engine and tranny have been out in the last years and come back in last/ this year.
There is a power distribution box below the brake booster. From my guess THIS should control the power to the E4OD. Extremely hard to get to, just 2" to lift the cover.
Please I need to fix this ONCE and for ALL time.
It has been an Ambulance so there has been something going on early 90ies when this thing was "born".
