I just got the 300 SD up and running again and I've been having an awful time with some sort of short.
When I start the vehicle, my tach will either race up to about 4,000 RPM or remain dead. When I touch a window switch, turn signal, or just about anything else electronic in the vehicle, the tach will start bouncing around. Once the tach comes online, when I accelerate, the tach will drop in RPM's. if I use the turn signals, the vehicle loses power, in cadence with the tach and turn signals.
Has anyone ever experienced anything like this? Seems like I can't be the only one who's ever had this happen. It is also strange to me because it doesn't seem like electrical issues should cause the OM617 to surge. Under acceleration, I can feel the vehicle surge with the turn signal. When the light is on, loss of power. As soon as it cycles off, power returns. The car actually lurches a bit with the use of turn signals upon acceleration. Turn on the defroster blower, same result; loss of power until I turn it back off.
I'm at a loss here. Maybe you all have some ideas?
Thanks,
John
