Battery Warning Light is now ON. Checked battery and had only 12.06 volts...charged on Battery Tender all day yesterday until the GREEN light on the charger came on. (FULLY CHARGED). Installed this morning. First time that I started it for a very short time...no warning light. Couple hours later...my nemesis is back. WARNING LIGHT reappears on the panel. My diagnosis/guess: Yes...have RTFM...Page 26...says "Battery is Not being charged." Suspect that BATTERY is not being charged by Alternator? Why? Perhaps a broken or loose belt? Before I start an afternoon of fun with the ALTERNATOR cover removal...anyone else have a hint? Thanks.
