Has anyone had this problem . When plugged in to shore power the house batteries charge but not the cranking battery . Maybe the isolator is bad or something else .
Thanks

Welcome to the forum. Others will weigh in but I believe in a coach of that age it was normal. You can but a TrikLStart that will take care of it

That is normal for that year & type of Winnebago product. The house converter/charger is not designed to charge the engine battery. You can add a gadget called A Trik-L-Start.  http://www.lslproducts.net/index.html

Similar but more expensive products are available as the Xantrex Echo Charge or Magnum Smart Energy devices

As built, most motorhomes do not charge the chassis battery from shore power.  The isolator is not for that.  Its job is to charge the house bank from the main engine alternator only. 

There are two choices:
Add a device marketed as a "Trickle Start"(spelling optional).  That will maintain the starting battery from shore power.
Or
Look up another device called a battery combiner by many suppliers.  This will cross connect the two systems when either shows charging voltage.

You also should try to find what is depleting the starting battery when the coach is sitting.

What they all said, shared battery charging from shore power has only been commonly found from the factory the last few years, thanks to smarter battery isolation devices which also act as combiners when any charging source is operating, not just when the engine is running.

Just like in most cars and trucks... the chassis battery, (aka: cranking battery), in my 24 year old, now 150k+ mile, Safari coach is ONLY charged by the alternator.... (and only when the engine is running).
