On board charger will show green lights when fully charged, (12 V. system). A "battery test" on my TM Head only shows 3 out of four lites after its been chargin all nite. Battery "one" green lite (TM battery) keeps blinking, while battery "two" lite (crankin battery) is solid green.

Chargin issue with the charger, malfunction with the reading on the "test" mode on my TM head, or bad cell in the battery????? Yawl's best guess before I go to tinkerin....and make things really screwed up!! Thanks
