Capt. George, Thank you for your quick reply.

First rule, learned the hard way!

I had to use an external battery charger because the boat had no power batteries/shore/gen. Mine works but not without shore power.

I just purchased all 5 Deka AGM batteries and will switch my battery charger to AGM charge mode. I have a CHARLES INDUSTRIES MARINE BATTERY CHARGER 50A 12V 5000SP which as per the mfg. is the only charger that has a selector between lead/acid, AGM or Gel batteries. I will also replace the damaged Emergency battery selector BEP brand model 701

My mechanic worked for the Cummins dealer and has contacts in the parts dept. so he will get me the alternator part number if I need it.

Thanks again!
