I keep getting hard starting on my newly acquired Cat 325BL from discharged batteries. It's currently set up with 4 Cat 31's that looks to be 2 parallel sets of 2 batts in series for a 24v system. If the machine sits for a week or so, even with the battery disconnect switch turned off, I'll get 18-19v across each set of 2 connected in series. That's even after I measure each set of 2 batts at 27v fully charged after being charged by the alternator after a few hours of use.
I pulled all four batts and have them charging at the house tonight before I get them load tested tomorrow. I'm sure I'll find a bad batt or two (they're 5 years old per the date code) but I also want to make sure the previous owner didn't 'optimize' the wiring. I see some random wires disconnected near the batts so I want to verify the right cabling/wiring layout with a schematic. Anyone got a pic of the battery cabling schematics? Can I go with 2 batts or do I need all four for Central Texas cranking?
