Jason - The "Check Battery" light suggests a problem with the alternator (typically). The battery that you bought should be fine if the charging system is functioning properly. What I have found is that the alternator can be producing the correct voltage, and yet be producing little or no amperage. This condition causes that light to come on. I would recommend removing the alternator and having it bench-tested, as well as generally checked out. If you have the Ducellier version of the alternator, it is essentially non- rebuildable (according to an alternator rebuild shop), and should be replaced with something better. The various vendors have options for you, from NOS replacement alternators to upgraded units of different flavors. I personally installed a Delco 108 amp alternator, which required a small amount of modification to the attachments. Other options require no modifications at all.
