Big dirty caught fire :(

[1tonchevy]

so tonight went to run to the shop for a part for my tow truck and I jumped in my dually to go and it acted like the batt was dead. so i jumped out and ran to the tow truck to get my booster pack. come back pop the hood brother hooks up the booster pack and as i go to crank it over smoke come bellowing out from under the hood. so i ran to grab my tools to disconnect the battery.

both the pos and neg wires were burning hot.but i managed to get them disconnected. and its took dark tonight to asses the damage but im not looking forward to it tomorrow what a crappy day!
