MDC should have no effect on voltage and typically when you have a problem it's with gauges not working at all. I'm thinking grounding which tends to be the number one culprit. Start at the block and clean every connection, check every connector for condition to see if you have corrosion or a loose connection. Work your way from the engine (the ground source) to the battery then to the dash. Not fun but it's typically where you'll find the problem.
