battery freeze ?
If you run down your battery and it freezes it will damage it. I need to pull the batterty out of the farm forklift tomorrow. charge it and keep it in the heated garage until we need it again. Ford 7.3 owners manual says not to use starting fluid. our John deere tractor mechanic said he used to pour gasoline on a rag and put it in front of the air filter on his 7.3 truck to get it to start.
