Another question_

Yesterday I got the new batteries installed_..I am not certain if my problem is yet resolved, however during my checks from yesterday sessions I noticed that only of the two batteries seems to be getting a charge from the alternator when the engine is going.

I am now trying to determine if anyone has an idea why that might be ? Basically the ground on the two batteries is linked together before being connected to the ground on the engine block. The positive on each battery is each connected to the appropriate terminal on the battery switch. And yet once the motor is started only battery #2 will show over 14 volts at the terminals whereas the first battery show the normal mid 13's range.

I am trying to figure out why this might be or is it common that the alternator only puts out enough current to only charge one battery and the second one to a lesser degree ?
