Re: 99 mercury cruiser wont start or turn over

Bach to basics and a some crude tests
Battery cable ends ,clean tight, and connected(you`d be surprised)
Making sure there are no gas fumes, short the small lug with the yel/red stripe to the main batt. lug on the starter,turns over or it dosent
Explain "juice to the motor"
