2008 Beaver Patriot Thunder Battery Configuration

<< < (3/3)

Steve Huber:
Ante,
I stand corrected. Joel was correct. The 3 battery setup supplies the needed CCA (~2850) which is more than the 2 battery setup speced for the CAT engine (1900-2200). You should be ok with this setup but may want to change back to the 2 battery configuration at the next battery change. Not clear why someone used the Cummins engine hookup for the CAT, but it works.
Sorry for introducing confusion into the discussion.
If I read your 2nd post correctly you said you had no electricity the first day of setup even when plugged in. Is this plugged in to shore power? If so it could be due to a faulty transfer switch. Does the inverter indicate low battery when not working?

Holy smokes guys - you are amazing!!!! We have been dealing with some grandbaby-sitting and had to leave the beast for a bit. We have discussed this whole thing over and over with the various mechanics and your discussion has helped immensly!!!! The cut-off switches are now labeled and we feel so much more confident about which ones are which. It seems logical now. The house batteries were not working when we first started this as the tech had put in new battery cut off switches in the battery compartment and had not connected something - the house battery switch did not "click" - - but also had managed to touch something and drain the batteries. They must have fixed the install and charged the batteries and we are back in business. A whole different switch - the one on the engine for a mechanic to start the engine from the back - has worn a lot and has been slipping which creates an engine comm failure. The new switch has been ordered. I think we are following through on some of these recurring problems and are learning along the way. Better to learn at home and not on the road!!!! Thank You so much!!!!  Ante and Ginny
