Hello, welcome and thanks for asking your question. My name is*****'m a Certified Auto Technician with 29+ years experience. I will do my best to assist you. please keep in mind that I may need to ask questions of you before I can answer. When you reply please feel free to add as much detailed information as possible pertaining to your concern.

Before you go any further, since it has been sitting a year, the batteries may actually be bad. At this time, I recommend to remove both batteries and take them to have them load tested. If they fail the load test, replace batteries as necessary..

Keep me posted...

Thank you,

Now what you need to do is to determine if power is getting to the starter at both terminals. The large terminal should have battery voltage at all times, the smaller terminal should get power when you turn the key to the start position. Get yourself a multimeter or test light to make sure that you are getting power at the starter and also when you turn ignition to start position on the smaller wire at the starter.

Post back the results..

Thank you,
