Steve,You can put a NE-2 neon lamp across the meter, and/or 6 or 7 forward biased 1N400x class silicon diodes in series. Neither will conduct significantly unless the 10K resistor goes open.

......And, if the 10k is bad you will get to see what happens to a voltmeter when offered 15kv.

With HV at, say 15kv, the volts across the 10k will be approx 2v thus indicating that the chain is intact.
