Problem

Have lt 1018 cadet that doesn't want to start. Turns over very slowly. Bought new battery. Showing good charge. But only getting about 5 volts at starter. Help

Attach a black lead of a voltmeter to the negative post of the battery and the red lead to the positive and try to start the engine, what is the voltage.
Now move the red lead to the battery side of the starter solenoid, and try to start what is the voltage.
Move red lead to starter side of solenoid and try to start, what is the voltage.
Move to starter and try to start, what is the voltage.
Now put the red lead on the housing of the starter and try to start, what is the voltage.

Did meter to battery voltage held. But only 5 at starter. Where do I find solenoid?

If it is not located on the starter itself, then just follow the big wire coming off of the starter and you will find it. Some are not bad to get to others are a royal pain.

do a quick check of the red lead on the starter housing and the black lead on the negative post of the battery. What is the voltage.
