Well, you sure had us fooled. When I read that, I wondered if that was a
typo. As to the negative terminal, get a can of Liquid Wrench, small size.
Put it on the thread and around the nut. Then let it sit for at least an
hour, if not more. I suggest the red and green felt washers for your next
battery.
Mr. Block, I kinda disagree with some of your numbers. I find good batteries
to vary between 12.48 and 12.61v when cold. CC charging systems put out
between 13.51 and 14.25 volts, and that's at idle, with no other electrical
load than the engine running. Those values depend upon the outside temp. At
45F the higher values apply. As the outside temp increases, output
decreases.
Brian: Better check your alternator output also, that 12.1v just doesn't
seem right. Was that battery check between posts or cable ends? And did you
alternate checks between posts and terminals and post-cable end?
Was it here on DML a few months back where that person claimed their system
was charging at 18 volts? Now that was a REAL bad battery. Biff
