I have a high mileage drz400s that was in good shape. While riding a trail I blew a fuse after repeatedly blowing 20a fuses I put in a 30a and instantly fried my wiring harness, ignition, and starter/kill switch. I have replace wiring harness, starter kill switch, ignition cannot find any other wiring damage obviously it's not associated with the wiring harness as I have replaced it. thinking it must be something other than the harness. I cannot find any visible damage to remaining wiring. Any ideas? What would u check next?
