unofix Posted March 12, 2021 Share Posted March 12, 2021 Sorry no idea of the location, but this type of fault can be caused by a poor ground connection from the negative of the battery. If the cable from the neg terminal to chassis has a high resistance then the charge controller sees the battery voltage as being low and tries to charge it. Also worth checking the bolt that fastens the cable to the chassis for signs of rust. Quote Link to comment Share on other sites More sharing options...
