  1. have someone turn the key to start, power should be on the little wire, that's the exciter wire. at the same time power should go thru the solenoid to the motor, check for power on the l shaped piece going from the lower lug to the motor. that will tell you if its the starter thats bad or the solenoid. if it's not going thru, you can take the back of the solenoid off by taking the 4 bolts off cover and clean the contacts and the flip washer. it will make sense when you see it

  2. if the solenoid is cluncking take a test light and see if power is going thru to the motor . if it is the starter needs attention if not the contact washer "the flip washer" in the solenoid needs to be cleaned or flipped and the contacts cleaned. common problem, will cause a hit or miss start
