Hey guys, I recently got a second hand Bruin and the 4x4 isn't working. You can hear it engage at the diff and the light comes on as well, however it is not going into 4x4. I checked the fuse and that's about as far as I went, I'm considering stripping it down to the wiring harness but it seems like a lot of work to get the racks and plastics off, I was told to try the relays and maybe check down by the diff with a multimeter however I am not too good with a multimeter. I basically want to find out if it is mechanical or electrical? But assuming I can hear it engage in the light comes on would that eliminate an electrical issue? Any tips would be appreciated or tips on what to check for with the multimeter. Thank you.
