Starter failing?

[tmr7s]

I have a 200 hp yamaha - when i crank it over, it doesnt respond right away - then cranks slowly and finally cranks fast enough to start, although not fast enough to suit me. This happens even with two batteries in parallel - one new and one 1 year old. Engine is 15 years old. Is this the signs of a starter beginning to wear out - any help is much appreciated - thanks tom

Re: Starter failing?

Sounds like it could be the starter or bad / poor connection or cable. It you have a voltmeter you may want to try this simple test...

To test the positive cable / connection:

- connect voltmeter positive lead to positive battery post.
- connect voltmeter negative lead to stater solenoid's positive connection.

** be sure to remove one voltmeter lead before cranking stops so you don't damage voltmeter **

- Crank engine... voltage should not exceed 0.5 volts. Greater than 0.5 volts suggest high resistance in positive cable / connections.
.

To test the negative cable / connection:

- voltmeter negative lead to negative terminal on battery.
- connect voltmeter positive lead to starter ensuring good contact with metal.

- Crank engine... voltage should not exceed 0.5 volts. Greater than 0.5 volts suggest high resistance in negative cable / connection.

In both cases connect to the battery terminal and not the cable at the battery, since you are testing the cable and connections.
