I have an rd6800 that is a little over 3yrs old. I have never had any probs til now. The unit stopped generating power from all recepticles. Yamaha engine still cranks on first pull. I have replaced the Voltage regulator and BRUSH assembly in hopes that it would fix my problem, but no luck. Repair shop says it could only be the (gen head or stator) but that it only comes in a kit that runs $360.00 anyone know of a less expensive solution?? Any other ideas?
