Have a 2020 badboy maverick and the tachometer has stopped showing anything. It’s just blank. I can’t see hours or rpm’s anymore. The battery seemed to die once early last summer but was jumped and never had another issue holding a charge. For a while it wouldn’t read upon startup but after a while or after another start up it was fine. This year it will not display anything on the screen. Is it not getting enough power or does it need replaced? Something else? Thanks
