Use a digital multimeter across your battery posts, key off. 12.6 volts is generic spec for full charge. Take same reading key in the crank position, shouldn't drop below nine volts.
Another thing you can try, turn on your headlamps, watch the lamps when you turn the key to the crank position. If the lites go out or almost, usually the battery or connections. If the lites stay bright, no reaction, key in the crank position, there may be an open circuit to the starter. Some of the national brand autostores will test the starter for you, if you take it to them.
