I dont know the actual ohms of them but the few I have had out of the harness were pretty long. I was told that the shunt carries about 9/10 of the load so if 10 amps are flowing 1 amp goes through the amp gauge and the shunt carries 9 amps. So the shunts ohms should depend on the amp gauge ohms to calculate the shunts ohms. And of course the longer the shunt the more resistance in the wire. They look like a normal wire to me but with a good bit of lenth to have the right resistance I assume. Ron
