Q: Ford Solenoid Switch in Lieu of Mopar Starter Relay?

I am still curious if the OP archlab has diagnosed his problem.This a simple system
to check,so there is no reason his problem can't be resolved quickly.Update?
As to replacement part quality,sometimes......... even buying"reputable"parts can
be disappointing,or worse.A friend/customer installed a new above mentioned brand
ign. sw., and started experiencing an intermittent no start while cranking.The switch
was replaced because they were dealing with an overcharge condition,which was the
result of an excessive voltage drop at the regulator sense wire,which is of course
the same circuit for the ballast hot,and alt. V in to the rotor.While checking and
repairing other connections fixed the charge condition,the no start reared its ugly
head again last weekend,and I made the house call.
After disconnecting the yellow wire at the starter relay, I checked the power to the
brown wire at the coil side of the ballast in the start position, nothing.The cause?
the terminals in the ign. sw. conn.(female) were oversized and when I looked
at them it's a wonder the damn thing ran at all!The pins in the OE connector were
lucky to touch at all.Luckily, the terms. were split,so I rolled one side in and sort
of "shrunk" them rollpin style.Done and down the road,but one more example...
