Why do you think 14.5 volts is bad? That is normal voltage. A "12 volt" battery is really about 13.2 at full charge (unloaded). To charge a battery you have to have higher voltage otherwise the electrons will not flow to the battery.
The problem is NOT the voltage reading he posted. Read the rest of the post........... Anytime you are blowing up light bulbs, more than an occasional burn-out--this means whether you are staring at the voltmeter or not, you have an overvoltage condition.
