Last year at the end of the year we rebuilt the motor in this sled, i ran it for a short period of time before fogging it and storing it. I started it tonight for the first time and after it started and was running for about two minutes the coolant light came on faintly. The coolant is at proper level and the motor wasnt even hot. The battery is dead and i started it by pull. Any ideas before i pull it of the trailer to check it out.
