Listen guys, two bikes in one thread gets confusing.
As a general comment, the factory Suzuki wiring for the charging system is weak. GSR common wisdom has it to wire the stator directly to the R/R, bypassing the factory wiring harness. Next, make sure the R/R is well grounded; many members here run dedicated ground wires, split, one to the frame and the second to the battery negative post. Lastly, how to route the Positive feed out of the R/R has a couple of options: one is feed back into the factory harness and through the regular fusebox and back to the battery, and second is to bypass that and run it direct to the battery with a small fuse holder added. If your fuse box and wiring in general is decently clean, using the fusebox is easier. If you are seeing resistance in those circuits though, a new wire with fuse saves time and energy vs. cleaning all the wiring.
Good luck and hope this helps.
