Hey Willard and Bob, I was just reading all your posts in this forum and wanted to say thanks on behalf of the many people you have assisted. It's appreciated :smile2:! Now on to my question :lol:. The motor: 1990 50 hp Mercury outboard - it's on a 20 foot pontoon boat; need to know HOW to specifically test the starter to find out if it's gettin' enough voltage and amperage to turn it (in order to make sure the key switch is not bad). When you turn the key, something clicks in the motor, but the starter doesn't spin at all. Have access to just about every electrical tester there is..... Thanks in advance for your help fellas :cool2:.
