I have a used 2007 RXT 215 and I have been having no end of problems. I have changed a lot of parts including the ECU, gauge cluster, main harness, engine harness, and various sensors. After installing the new ECU, battery, and gauge cluster, I'm getting low voltage and low fuel messages (even though there's a full tank). Also only the left side of my gauge cluster is working. Any help or advice would be appreciated.
