Thanks, I printed this out, but need to get a hydrometer.
Do my the Voltage readings make sense, by themselves or is it a combination of SG and Voltage to determine a bad battery. I found that online battery test directions again. It said anything reading below 9.3 is a bad battery.
But didnt specify if on the charger or with charger off. ON the charger, all seem ok, with the exception of 3 at 13+volts. But off the charger, they all would be bad by that standard?

Ok, got a SG gauge, checked all cells, they pegged out the gauge - floated above 1.3 on every cell, on every battery?

The only wierd reading I have is the # 3 battery showing 13+V on charge, 8.7 off the charger, but the 3 battery SG tested good.

What next? Still wont go.

Assuming the solenoid is clicking when you try to go... Attach the meter to the battery pack and try to go, what does the pack voltage drop to?

That sounds right, tape them on wherever you get your pack total reading. A bad battery will 'drop' under load. If you can test with a full throttle start uphill would be best.

All things being equal, I am thinking bat 3 with 6V is a problem?

Popped a new battery in for that #3 6V POS, charged and working like a champ, going to replace the others on a regular basis now vice as needed.

Did discover my frames below the batteries are pretty corroded and deteriorated, need to tacke that one.

Corroded battery frames are a typical problem brought on by wet venting batteries.
Note that replacing batteries 1 at a time may yield less than 100% results as mixing a new battery into an old pack results in overcharging the new battery. Over time this over charging can reduce the battery's potential. Better to pull out the CC and get 5 more now... and pay up on the card each month. (in my opinion)
