I didn't need to worry about getting a manual for this unit. Called Snap-On customer service and they in a few minutes they emailed me the manual as a PDF. Thanks, Snap-on.
I am looking for a user manual for a Snap-On MT 402 Alternator Generator Regulator Tester. Would be happy with a scanned or PDF file. Don't really need an original. My unit is Serial No. 27587, Model D.
