The 84 basically uses the starter as a junction box...which causes issues with heat being that close to the exhaust.
I added a junction box on mine before the battery relocation...was one of the best wiring changes I made. When I did that, I ran all the additional wires that used to go to the starter to the junction box, along with the alternator wire and an 8 gauge wire from the battery to the junction box. When I relocated the battery, I ran a 00 gauge welding lead from the battery to the starter (I am a firm believer in overkill) and an 8 gauge from the starter to the junction box. I ran another 00 gauge welding lead from the negative on the battery to the front crossmember support bracket for one ground, and another to the stock grounding location on the head (and kept the ground from the head to the decklid hinge). I ran the welding lead through plastic conduit on either side of the gas tank.
