[QUOTE="SteveO, post: 167581, member: 3636"] Well, I'd like to think I can. I wanted to test the alternator output independently to the regulator/rectifier for the reason Erik pointed out; there would be no charge if the latter was kaputt. The reg/rectifier is a Podtronics type unit, so the Alton, as you say, has no connection to earth. It has two black leads which go to the yellow leads on the Podtronic, the Podtronic then has a red, live lead to the charge side of the ammeter and a final black lead to earth. There was no charge on the ammeter, so I tried first getting a reading off the red lead, nothing, then removed the two yellow leads and went directly to the Alton. Still nothing. I tried connecting the two leads across the meter and also taking one lead through the meter to earth. Still got nothing. I should be getting something like 12.6V AC from the alternator with the engine running shouldn't I? I should mention that the Alton is off the bike now, is there a way of bench testing it? Presumably I could spin it over in the drill chuck? Can the Podtronics unit be tested? [/QUOTE]
