[QUOTE="ionbeam, post: 1263534, member: 277"] The display goes dead because the voltage drops too low. It could be wiring, the starter and possibly even the new battery though it is unlikely. The problem could indeed be related to melted grounds but this is an unusual symptom. The starter is easy to change, getting to the starter is a bit involved. This problem will take a volt meter to diagnose, if you don't own one or aren't comfortable using one then it's probably dealer time. If your FJR hasn't had the ground harness recall work done yet you need to take it to a dealer anyway. If you aren't sure if the harness rework has been done you can call any Yamaha dealer and give the service department your VIN and they can look it up. If you have a meter and can use it, we can walk you through a diagnosis process. Ideally the diagnosis process will start with your battery being trickle charged over night as a first step in troubleshooting so we know what we are seeing when measuring the battery voltage under load.
