I found that the previous owner had purchased the MB workshop manual. I followed the proscribed step by step diagnostics given in the manual to see where the power supply problem might be. The overvoltage relay checked out OK according to the decision tree that was published. The voltage relay did not check out.

My question(s): 1) Since I do not have the lambda testing apparatus do the voltage readings that I obtained from the various terminals on the voltage relays mean anything? 2) Have you ever heard of the voltage relay giving out instead of the overvoltage relay?

Again, thanks for the tech support. I am learning more about the car every day!
