Jeff - 12.25 V is a little low for a battery at rest. Normal should be 12.56-12.95V. Put a charger on the battery and charge it up and let it rest for a couple of hours. THEN check the "at rest" voltage again. If it goes up to the range I said above - the battery is good. If it doesn't - have your battery checked - it could be on it's last legs (weak cell). If the "at rest" voltage goes up to the range I said - then it is only an alternator problem and 95% possible it is just the brush pak. With a new brush pak expect 13.4-13.8 V at idle and over 14V at revs. Brush pak is available here at Fastlane and is two screws to replace - 10 minute job - very easy.
