I have a 92 500E that cannot hold a charge. My mechanic has determined that the control box for the ignition system is not powering down and is drawing 1.5-1.6 amps. Mercedes is estimating a replacement part at $2200, which puts me in a position of junking the car.

Does anyone have any suggestions on where I can find one of these for much less than $2200?

I've owned this car for 4 1/2 years and in that period, have put over $11,000 into keeping it running. I love it when it runs, but that's only about 75% of the time.
