I just re-read it. Still need to know what kind of circuit OP has as to whether the ground goes through a network to operate. I three posted unit will not work in a four post system.
You need some understanding just to comment on this subject.
He is replacing;
120 105452-6, A solenoid with TWO large posts (for the battery connections) and a single small post for activation of the coil. Total = 3, because the coil is grounded internally.
WITH the following;
120 105752-6, A solenoid with TWO large posts (for the battery connections) and two small posts for activation of the coil. Total = 4, because the coil is isolated i.e. NOT grounded.
I could walk you through the specification sheets for each relay if required.
BTW - I would be very interested in seeing the RV system that uses circuitry to switch the solenoid coil ground.
