[AT] Tractor lighting puzzler

[John Wilkens]

Trying to understand Doug.  Would that explain why both poorly grounded 
lights with separate circuits from the switch turned on dim when only one 
circuit was switched on at the switch??   IE:  One light working OK (as 
switched) on the good fender but both lights dim at the same time on the 
bad fender.    John
