There IS a delay. I've yet to see the one for the field relay work, but
it IS there.The ones for the armature resistance contactors usually

'sensing' wiring concern.
Maybe. I saw on one schematic that there is a hand-drawn X through wire 8's connection to the motor side of L1/l2's contacts and a hand drawn line connecting it to the battery side of L1/L2. Haven't checked my tractor to see which side it's on, that could bypass it. 
Note: I do have a MOV and it's not blown to bits. I am actually thinking 
of replacing the relay with a spare pair of E20 push/pull contactors, 
but I would bet the field voltage spike is so high it would blow those 
apart (the armature reversal on the E20 has a lower winding count thus a 
lower peak voltage with the field nailed on)
