Hello all, I'm kinda stumped and looking for ideas. My wire harness from generator to junction box burned up, then looks like it traveled to the ammeter.

I've replaced the generator to junction and the junction box to ammeter harnesses. I've now also added a 30amp battery fuse at the starter. I also added fuses to the generator cutout on both the junction side and the lights/horn side.

I am 6v positive ground. When I turn on the battery disconnect, the 30a fuse between the cutout and junction box immediately blows. The 10a on the light side has not blown yet. What could be causing this high current? I measured my ammeter which has 0.1 ohms resistance. I have a new cutout and ammeter ordered, but not convinced they are causing the high current.

The key switch measures 4.22 amps and 6.25 volts. 6.1v at ammeter with fuse removed to generator cutout. Over 10amps at ammeter.
