Recently had a problem with my CVR. I replaced it with a modern fancy one and I have it set to put out 5v. Now the gas/temp/oil gauges don't read at all. I have checked then double checked and triple checked to make sure the gauge posts weren't grounded to the housing. I have used a volt meter from the posts to the housing. It reads like it's grounded when the new CVR is connected. Not sure if that's normal. No grounds when it's disconnected. Any ideas?
