A standard voltmeter would work fine...you are looking for excessive current draw, so measure amperage, not volts.

Note: I had a Jaguar that would suck the battery dry within a couple of days. The cause was a faulty alarm brain...aftermarket issue. Yanked the offending alarm and all was well from then on.

As far as the "flashing issue", likely unrelated to the unusual electrical drain. It's usually a symptom of a bad or loose ground in the illumination system. Typically, the "bulb-out" indicator circuit. The flashing should be prominent when applying brakes while the car is at rest.

I had the "flashing" occur as well. The culprit was due to loose metal grounding strips in the taillight housings. They also caused phantom "bulb-out" conditions, even when all of the bulbs were the correct type, wattage, and tested fine.
