Follow the ground wire from the battery to the other end after first disconnecting from the battery. The other end when you find it, see if it is soaked in oil or if it is loose. Even if it isn't, it might be a good idea to disconnect, clean real well and then reconnect tightly. A bad, loose, dirty ground could lead to the battery not being recharged.
