Thanks for the suggestions.

They got as far as Laughlin Nevada before coach quit. The hired driver was able to purchase 4 new engine batteries and went another 40 miles before noticing decrease in voltage.

They were out of cell range and were long past due so I hopped in the car and went with another Prevost Owner heading down the road from Las Vegas to Laughlin, NV and we finally found them.

Alternator was not doing its job so we disconnected the hot lead from the alternator and since it's a 24 V coach with 2 separate 24V systems we took a jumper cable (nce engine was running) and tied the two battery systems together by jumpering across the battery Isolator.

Ran generator to keep batteries charged via inverter and were able to drive tie 75 miles back to vegas at night with all lights working.

Now, need to replace alternator. Anybody want to buy 1996 Liberty Elegant Lady 45' from upcoming estate sale?

Owner was killed Saturday in first solo flight in ultra-lite Trike.
