I have posted warnings about this problem several times over the years.
It is caused by a conflict between the factory aux battery relay wiring
and the added Hard Start Relay. It can also be caused by a Westy Fridge
relay if wired a certain way. In any case, the fix is simple. Slide the
driver's seat forward so you can access the relay under it. Find the
smallish red/black wire that plugs into it and make sure you can
remember where it is attached to the relay. Pull that wire off the
relay. Now verify that the starter problem is gone. If it is, proceed as
below.
Then you still need to replace the pulled wire with another short wire.
First, tape over the end of the pulled wire so it can never touch metal
and then tuck it out of the way never to be needed again. Get a 4" or so
piece of wire about the same thickness as the pulled wire. Put a female
spade on one end of the new wire and a ring terminal on the other. Plug
the female end into the relay where the pulled wire was. Using the small
screw that holds the relay to the body, pull the screw and put the ring
terminal over it, then put the screw back in holding the new wire and
the relay.
