Many thanks for the starter advice. I installed a new gear reduction
starter with the Westy Ventures adapter today and couldn't be happier. I
was considering replacing the factory +battery cable with some welding
cable but I decided to leave it be for now. I'll probably try the load/no
load multimeter test but it seems to be starting the van effortlessly at
the moment so hopefully I'm all good.
Thanks again!
Michael.
