changed battery turmal now the starter wont engade someone said it was my securt

You changed the battery terminal end why? what was the orginal problem, signs and or symptoms that caused you to change the battery terminal end? Always check the connections that provide current(electrical power)for tightness or loosenes, or corrosion. Never wear jewerly when you are working around the battery.

shouldn't have any thing to do with sec. is the battery strong? is the starter the original unit for car? things to consider. rec. u have diagnostic run. worth knowing what problems are.
