I want an oscilloscope to be able to test alternators [1] and because they've got wavy lines, they're great.. [URL]http://www.mztech.fsnet.co.uk/electrics/alt_osc.html[/URL] Ebay has them, what type do I want, what type to avoid, how much etc. I honestly have no idea in this department. Any one got one to sell, cheap? [1] I mentioned this a few days ago and now I want one..
