I bought this starter off ebay. I bolted it to my trans and would like to see if it turns my SBC 350 over. How do I jump it? I don't want to start the engine. I just want to make sure it engages the flywheel and cranks the engine. I connected jumper cables to my car battery and connected the hot lead to the top of the starter under that black boot and touched steel with the neg lead. It spun the starter gear but didn't extend it. I connected a wire to the spade terminal under the starter and touched that with the hot lead and the neg to ground and it extended the gear but wouldn't spin it. I jumped the spade terminal on the starter to the ground I was using and touched both with the hot lead and it just spun, wouldn't engage. Any thoughts?

hook up your jumper to the bottom large nut and then use a small alligator clip lead to energize the spade stud next to it.
The solenoid kicks the gear into the flywheel. You need to energize the motor via the solenoid. Rich |

You need to energize the motor via the solenoid. Rich Hey Rich, so I should use a alligator clip/wire and clip it to the spade and the other end to the large lower nut? Then connect the hot jumper cable to the nut and the negative to a suitable ground? |

You need to energize the motor via the solenoid. Rich Hey Rich, so I should use a alligator clip/wire and clip it to the spade and the other end to the large lower nut? Then connect the hot jumper cable to the nut and the negative to a suitable ground? The answer would be yes, but you do not leave the alligator clip secured to the spade terminal. You jump between the battery lead on the starter and the spade terminal to get the starter to function. In a normal situation, when you turn the key to start position, switched power is supplied from the ignition switch to the solenoid (big yellow wire). This energizes the solenoid which shoots the bendix out to engage the flywheel teeth and engages contacts (inside the solenoid) to supply battery voltage to the starter motor. When the key is released to the run position, the power to the solenoid & starter is cut off. Oh BTW, the IMI brand was started by Pat Isom, Isom Brothers Rebuilding (electrical rebuilders), in Whittier, CA. He downed the business a few years ago due to health reasons and someone took over the IMI Line. |
