I'm trying to understand the battery wiring better. I have a 1987 Hunter 34. I seem to have to set the battery switch to '2' to be able to start the engine without engaging the emergency cross connect. Does this make sense? Also, after sailing with the engine off the volts go down to 12.6 on the engine batteries and to start I must turn the battery switch to 'all' then engage the emergency cross connect to start. DO the batteries just need to be replaced? How do I check to see they really need to be replaced?

1. trace your wiring as we can only guess how the batteries and switches are wired.
2. 12.6V is an indication only that the battery could be fully charged
3. Only way for you to know definitively what the capacity is of your batteries is to load-test them

Manuevers...
Consider putting in the infamous supplemental starting relay that takes the solenoid current off the starter button wiring and uses the button to trip the relay for a higher current capacity connection between the battery and the starter solenoid on the starter motor. This seems to be the cure for your type of problem (which we've all had), especially with the batteries at near full charge.
