Message: [QUOTE="sootie, post: 1492282, member: 8162"] or there is a short in one/both batteries which creates a power sink. try isolating them one at a time and see if anything changes. You could also do a test with a multi meter. take the terminals off the battery. Set the multimeter on VDC. Pop the caps off the top so you can see the acid. Put the red lead on the positive post and dip the black lead in the acid in the first cell. Write the number down. Move the black lead to the next cell. they should all increase by 1.5 volts. If there is one that reads zero or is a much higher number, you have a bad cell or a short. [/QUOTE]
