I think the easiest way to check it is to split them (on my 1700, there is a wire leading to the first plug, with a metal bar between the two), so remove the knurled nut on the two plugs and check the resistance with a meter. If one (or both) is open circuit, it is (they are) toast. If you don't have a voltmeter, you can probably use one of the circut checkers (light bulb in series with the plug and the battery).
You could also pull them out and take a look at them. Mine were clearly deformed (like it melted inside) when I took them out. Not sure that looking at them would tell you in all cases, though.
