The kit comes with a heavy duty cable we have run off the battery via a fuse , the plug that came loose was one already fitted at the end of the cable . We had to make a plan with the Harrison crimping for the solar side of the kit we put together using the bench vice .Problem is now the cable is in the bus so we wont be able to get the end to the vice .Guess we will have to make a plan with a G Clamp .
H.e. managed to get it fixed today with the vice grips and some muscle by the eldest rugrat .Seems pretty fixed now will report back during the next two weeks if we have power
