Go hook it up to your car. Plenty to look at there.

I agree with Spence, but if you wanted to you could bench test it. Just hook up the battery charger to the positive post and have a jumper wire from pos to the solenoid terminal. Then put the negative cable to the starter housing. I would put the starter in a vise to be safe. Then just hook up your amp clamp to either wire on the battery charger and engage the starter. You will then see the current reading.

Hint: Getting started with your scope posts are best placed in one of the Picogroup area boards.

Getting some amperage waves from the neg battery cable while cranking would be a great place to start

pun definitely intended :)
