Get a voltmeter and do a voltage drop test across the battery terminals and cables.

Place one lead on the actual battery terminal (do not touch the cable or the cable leads). Now place the other lead on the battery lead. Have a friend crank the engine. Set the voltmeter on 2DCV, your reading should be no higher than 0.2V. Ideally, you should have a very low reading (around 0.01-0.1v). Do this test all the way up to the underhood fuse box, just follow the positive battery cable.

Below is a good link on how to do a voltage drop test on your vehicle.
