Yes take it off the frame and clean it and the frame. Put it back on. Up front there is a Motor to frame. May as well just clean them all. I am sure they all like that. Battery neg bolt to the motor. There is a frame to core support and frame to body.

If that don't solve it you got to drop the tank. On the sender there another connection. The other end of that wire that is on top.

I would buy 4-5 new straps and just run new ones all over.
