I'll consider that, but 'tis more fun to DIY. Max -- Sent from my Android phone with K-9 Mail. Please excuse my brevity.

Where do you connect the probes, at the battery or at the alternator? Max -- Sent from my Android phone with K-9 Mail. Please excuse my brevity.

I have used an oscilloscope a number of times to identify a failed diode in an alternator. If you have one - go for it. If not, it's probably not a good enough reason to get one. -- Philip _ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] scan tool
O-scope will show any ripple in the output, which will identify a bad diode.

[MBZ] scan tool
I was going to buy a USB scan tool http://www.obdtester.com/obdtester to get my truck sorted out, but ended up taking it to the garage and they scanned it, reset the distributor, and got it sorted out for less than the scan tool costs. I don't think a scope would do what you need, the computer keeps track of what the sensors and such are doing, and the scan tool will report on that in real time so you can twiddle with it. Probably the way to go. Not sure what a scope would do with the alternator, you can take it to the FLAPS and let them test it easy enough with their tool. The scan tool might track its behavior too? --R On 9/22/11 8:40 AM, Max Dillon wrote: I may need to test Infiniti alternator with your O-scope. Do you have a scan tool?
