Replaced the auxiliary battery under the seat. The new one has two vent holes either side of the battery. I have a vent hose connected to one side. Do I leave the bung in on the other side?
Conflicting information online especially as the supplier states bungs must be removed before using. My feeling is that the vent holes are connected so you only use one, other wise you would need a pipe on the other one as well. Am I correct?
