Re: Starter Problem??
Put a volt meter set to DC volts red lead on the small terminal(probably some kind of yellow wire going to it) and put the black lead on the black lead on the battery. Have someone turn the key to start position and see what the voltage goes up to. Disconnect both big red leads that go to starter and battery and put meter on Ohms range. Touch both big leads with ohm meter. You should read infinite ohms or no load or the same reading you get when nothing is connected to the meter. Next have someone turn key to start position. You should see real close to zero ohms across the two big leads on the starter that the battery and starter were connected to.
Cleaning leads is the first thing you should do. If you read less then 9 volts at the small lead you are creating a voltage divider. What this does is the resistance is so low on the solenoid that only part of the 12 volts is going to the solenoid and the rest is going to the wires and switches. To fix this you will want to clean and shine and tighten starter leads, battery leads, neutral interlock leads, barrier strip leads and the leads going to the ignition. Basically anywhere the yellow wires go they need to be cleaned.
