(ET) E20EA troubles - and here comes the snow!

[Max Hall <mhall maxmatic com>]

Hi, all,

I'm stuck. No forward speeds, no reverse speeds. 

My ol' manual only has schematics up through AA and BA, and I think I'm missing something important!

If I use my finger to actuate RTN or RTN-R, the tractor behaves perfectly. But neither RTN not RTN-R will pull in by itself!

Anyone have a schematic for the E20EA?
