This customer brought the car into the shop for an intermittent no crank issue on his 1997 Toyota Camry. Customer stated that the car does nothing when it happens and if he turn the key on and off and few times the car will start.
I was able to get the car to act up after about 5 start-ups. The car did do something when the no crank condition was happening. It clicked when I turned the key to crank. The clicking was coming from under the hood and was quite noticeable. Since we recently covered the starter testing in the Automotive Weekly Waveform group I decided to grab the scope and get some captures.
Lets go over the captures together and then take apart the starter to see what caused the issue.
