Normally you have the large positive cable from the battery to the large "batt" stud on the SR then a seperate large cable from that large "batt" SR stud down to the large terminal on the starter. Then there is a smaller brown (if OE) wire from the SR terminal that has the mini bolt that secures it & this wire goes down to the small "solenoid" terminal on the starter next to the larger starter terminal. Correct so far? not being patronizing just wanting clarification so we can get a handle on this. If the SR was bleeding current down to the solenoid via the brown wire the starter would be energized (that's fairly rare). If the solenoid hold in winding was being energized internally from the starter large terminal (extremely rare) if would feed back to the (brown if OE) wire & there would be a slight draw in the large cable from SR to starter which would show up as a draw you are seeing at the batt & if that is the case pulling the brown solenoid wire would not stop the draw (cuz it is feeding back into it from the starter) but pulling the large cable would. but we're missing something here in how it is wired. Holler back when you can. EDIT reread & lets cut to the chase, take the wire/terminal (11/32" nut) off of the starter solenoid terminal & see if that solenoid terminal with nothing on it is hot & if so R&R the starter & if not see if the wire/terminal you removed is hot & if so the SR is bad (not likely as you replaced it) & see if the yellow wire/terminal at the SR is hot (if so it is being fed from the ign sw or bulkhead crossover) but not likely cuz if it was recieving full voltage the starter would be cranking. I still think something ain't routed right on the wiring but...
