Hello fellow Guzzisti.

I´m having some trouble checking the winding isolation towards ground of the alternator in a 96 cali 1100 carb. The service manual sais to connect one point of the ohmeter to a yellow alternator wire and the other to the ground (laminar pack). In all the other procedures the alternator checks ok (winding continuity, voltage output), but I cant seem to check the winding isolation. :(
Are there any other procedures to check it, and if not what can be causing the problem.
The bike has no regulator installed because it burned :eek:hmy: (the regulator, not the bike) and melted the ground wires from regulator to frame, dont know if that has something to do . . :dry: :oops:
 
It sounds like the alternator is OK. If it wasn't isolated correctly, you wouldn't be getting the voltage output IAW the manual, it would bleed off to ground. Also any ground is ground for checking the winding isolation, engine case would be easy to use.

It isn't uncommon for the regulator/rectifier to fail. Although the failure is usually less dramatic.
 
Yes I´ve tried it in the case and in the frame, and in the negative battery contact with no reply ;) but in the service manual says that the instrument should indicate a value above 10 MOhms. :huh:

By "no reply", do you meant zero ohms or near infinity (an open). If the meter is just ranging, then it is above the specification. In this case, infinity is good.
