1605 install installed insulation and add third batteryadded a .third battery. One of battery terminal lugs was lose when we arrived. That may have had some effect on charging but minimal if any. The TRH fan definitely 'noticed' the voltage swings as we paralleled in a 3rd battery onto the one that had the lose terminal.
Notes:
1> HRT TRH fan is noisy , needs and may need to be replaced. It did sound more steady after adding the 3rd battery.
2> 2 Batteries' caps were/are mising. One of battery's lot is losen.missing.
