Yea sounds like the rectifier. To test it you need a voltmeter
Charge the battery and make sure its at 12 vots or higher
Turn on the engine and slowly rev it up to 5k or so
The voltage should rise as you rev it up to like 14 volts
If the voltage goes down as you rev or stays put then replace the rectifier.

DON'T test current across the battery terminals, just to make that clear. It's something of a safety concern. Test the voltage across the terminals, and test the current in line with the ground or power to the battery if you are curious about that too. If you set the meter to DC Amperes, and measure across the battery terminals, you might end up holding something that will have become on fire. Look at the "Regulator Rectifier Problem Solved" sticky thread for the procedure.

wait... so you're suggesting that if you connect one multimeter lead to the positive terminal and one to the negative and turn the multimeter to DC Amperes, that the meter will give you a reading of any value at all and also not harm the multimeter?
