This has nothing to do with an oil change. Electrical problems can show up anytime. You can find a perfectly fine digital voltmeter, (multimeter / DVOM), at Harbor Freight Tools for around five bucks on sale. Sears, Walmart, Radio Shack, and any auto parts stores and hardware stores have them too but you'll pay more and you'll pay for features you'll never use. All you need to make me happy is a meter that will read DC voltage to one decimal place, . . . two is better.

but instead of having a helper try to crank the engine, just turn on the head lights. With the type of symptoms you're describing, the head lights may draw enough current to make a bad connections identifiable.
