My gauges were not accurate either, and after a lot of troubleshooting could not figure out the problem. A call to the manufacturer gave me advice on wiring. The ground wire on all 3 gauges needed to run directly to the battery, not to a common ground. I ran a separate grounding wire from behind the sliding door directly to the ground side of the first battery, and also regrounded the wiring directly behind the gauge panel. I've only had the opportunity to check them once, but they appear to be working accurately. I really don't know why this matters, but it does appear to make a difference.
