My first new KAE was no good out of the box. Second one has been working fine for 3-4 years (80,000 mi). I'd recommend the MB OE unit.

Maybe check the fuse in the existing OVP top before buying a new OVP. Also there is a fuse in the fuse box (see fuse box lid reference index for tach / fuse #) that when "iffy", will exhibit similar symptoms.
