I was tracing wires from the CC relay on one my E-20 tractors (EC) I
unexpectedly discovered the VDR-1 is gone. One end of each soldered
lead is still soldered but the other end of each is "dangling" in
mid-air with the "body" of the varistor missing. 1. I found it on the
Schematic and Connection Diagram page 7-16 but have no clue what it is
doing! What might I expect to be a symptom of its absence?2. Where/how
do I find a replacement? I would leave what is existing and solder
the new leads to the old existing ones. Is it directional? Jim shows a
varistor in his catalogue, haven't heard back from him. One other
unrelated item. On the same Schematic there is a drawing inset
describing a modification issued via letter on June 18, 1973 regarding
adding a wire splice and a diode. I am not savvy enough to be able to
look at the tractor's wiring and determine if the modification has
been done. It appears to involve a relocation of wire 41-01 but I
can't figure out where to exactly. (Not something easily described via
email w/o drawings and/or photos.)
