Having an issue when the weather drops below 45 degrees, the GL goes crazy with lights and will not go into gear. Goes into safety mode. We have replaced the main battery and cleaned the connections. That worked for a short time. We can reset the be removing the negative and it resets and is fine. There is no Aux battery warning at all. Not sure if that needs to replaced. Same issue this morning since it was cold, we removed the negative, reconnected started up fine. left it for about an hour went back out and it went haywire again. Any thought? No issues with warmer weather....
