something is draining my battery

I suppose it could, but it wouldn't be very hard to bypass. It's just going to disconnect the PD box or somesuch or it will be prohibitively expensive to install. Or else it just disconnects one critical system like the ignition primary or the fuel pump.

But a REALLY easy way to tell is to disconnect that alarm and crank the vehicle (with a jumpstart if need be).

I strongly discourage using a test light for this because it isn't a terribly sensitive test. Use an AMMETER, preferably the clamp-on type. If you had two 500 mA drains, you wouldn't be able to find them with a test light, but it would be obvious with an ammeter.

I disagree, 100mA will light up most test lights bright!

Bob, read the whole thing.

Two 500 mA drains will be undetectible with a test light. No matter which single wire you disconnect, you will always light the test light bright. On the other hand, with an ammeter, you will see the drain drop by 500 mA when you hit one of them.

It's not THAT unusual to have multiple problems.

Test lights vary on what they draw, depending on the size of the lighting element used. LED test lights will only pull about 20mA, and large incandescent bulb lights can draw around half an amp or even more.

Although a test light would serve the purpose if pulling fuses to locate a drawing circuit, a meter would be the best choice for this kind of troubleshooting, as it would show the real draw and there's no guessing.

Sorry, my bad!!!! I have to agree with you on 2 separate current drain problems! I will say, I've never seen 2 at the same time.
