Anyone who has problems with their Gauges should contact Jim Walker. I have an LS400 that had the power meter boards failing ( instrument lights/needles flickering, not coming one until warmed up, etc) and Jim had them fixed by the end of the same day that he had received them - and they work great!.
I ran into a few self inflicted errors as I re-installed the boards (by the way Jim also provides an excellent do-it-yourself remove/install set of instructions) and Jim provided me with helpful suggestions to track down what I did wrong.
In any event, for the sake of an hour and a half of my time I saved over a thousand bucks by using Jims services.
Very easy and professional all the way - Highly recommended!!
