"Truck wouldn't Turn OFF" Need Help

[petey-pablo]

Ok guys I know this was coverd before But I can not seem to locate the thread. Heres my problem I fired up the beast today I knew I had a problem as soon as I hooked up the battery The Electric Fuel Pump & Electric Water Pump came on But I decided to try to start it anyway. After a few putt putt backfire and a louder backfire and a small fire on the Carb It was ok notthing was hurt... Then I tried again putt putt and it fired up after a year of sitting in the garage I changed the Altanator wireing and Cleaned up the Wireing under the hood. But when I turned the Key to turn it off it wouldnt turn off I pulled the Fuse to the Fuel Pump and disconnected the battery then it slowlly turned off. What did I do wrong with the wireing any Ideas of where I should start Trouble shooting?
Thanks everyone I am running a 454BBC MSD Dizzy My altanator is a 10SI Internal Regulated model. I am useing the stock wire harness undre the hood and a Painless fuese block under the hood to power my Fuel Pump, Water pump, and Electric Fans hope this info helps....
