I fixed the problem on one of the DP's I work on by using a Runtz dropping resister that is made for dropping 12volts down to operate 6 volt gauges on cars that were converted to 12 v.

I'm having the same problem with a 16 volt battery.i tried the runtz and voltage went from 16 to 7 and they don't like that either.any other ideas.
