Honda trx 420 2012 electrics

[avag]

I have a 420 and as soon as the key is turned it blows the 10 amp ignition fuse wiring seems good hasn't rubbed anywhere if I unplug the grey connector from the ecm fuse doesn't blow and dash lights up so I suspect a faulty ecm just checking before I order one has anyone come across something similar ? Thanks

Go under r/h rear wheel arch. Unplug the wires from to regulator / rectifier. Replace the fuse and see if it blows.

I removed both connectors off the regulator and it still blows the fuse it only stops blowing fuses with the grey connector removed from the ecm
