Larry and Donald, would you happen to have a model number of the meter (vom) that you have or wish you had? I sorta looked at Sears website, but only found expensive meters that did duty cycle, not a $30 one so far.
I gotta do some of this stuff myself, because the closest Mercedes dealer is about 210 miles from me. Heck, even a Sears is over 90 miles away.
I thank you all for the help and suggestions you give to all of us.
