I have a BJ73 with a 3B in it and have a problem with the Electrics.
Truck is ok until I put it into 4X4- then the engine fuse blows. Either via the dash button for H4 or the transfer case lever for L4. I have metered the transfer case solenoids and they seem ok. I Cant fine the Transfer Case Relay. Does anyone know where this is in a BJ73?
Of Course this happened in Westport on a Club trip, 100 meters into the first track.

I was able to drive it home so that was some small comfort though..
Thanks
