Hi,
I am looking for a wiring diagram for the 1981 900 SS. Anybody know where I can find one? Specifically I am interested in the charging part and how the voltage regullator wires up. On last thing, anybody know if the red generator light is meant to stay on or should it go out once either a certain RPM is met or the battery is fully charged. Thanks

I'm not sure what the problem is here. Is it simply that the generator light stays on all the time?
As suggested previously have you checked the voltage at the battery with the engine running? What numbers did you see? Does the battery actually hold a charge?
Anything I have seen on the SS models indicates that the generator light stays on all the time. As I remember the same was true of my 860GT. I have been running my SS for 25 years and the light has always stayed on.

Bruce,
The original problem was that the battery was not charging, it being new, so I went looking. Last year I had replaced the wiring from the pick ups (they were totally shot) so I assumed the wires from the stator were in similiar condition. I took the stator out and soldered new wire to it and put it all back together but don't really know if the regulator is wired correctly as it could have been incorrectly done by the previous owner. I haven't run it yet to find out the output, before I did I wanted to be sure the regulator was correctly wired

Thanks a bunch. I'll wait to hear from you. My regulator has only 4 usable connection tabs. The two marked G and closest to the ground on the mounted regulator are obviously for the stator and the one marked with a + sign (in the middle) I assume is hot originating from the battery, leaving the opposite end for the only remaining wire wich happens to be white. My fuse box although able to physically hold 5 fuses only carries 3
Its not that easy to make out the wire colours but I looked at my SS and then compared the wires to a diagram for a '76 SS. The results in order of terminals are:
first terminal G - yellow or white wire?
second terminal G - yellow or white wire?
terminal +B - red wire
terminal C - brown or orange wire?
terminal L - no connecting wire
According to the wiring diagram, the two yellow wires come from the alternator. On my bike they are in the same sub-harness and go to the front of the bike. The red and orange wires are in a separate sub-harness and go to the fusebox. The red goes to the battery via one fuse, the orange goes to a separate fuse then on to a number of electrical components. Although I didn't count the fuses I believe there should be four of them as shown on the wiring diagram. The diagram can be found on www.ducatimeccanica.com.

Thanks Bruce,
I fired it up after having soldered new wires to the stator and hooking up the regulator per the diagram and your input and low and behold the readins on the multimeter are about 11 amps at idle and 14 at 2000 rpm so it seems missin accomplished. for what it is worth the generator light stays on at thje dashboard. One small problem though, which I am going to post as a new question, is that the 25 amp fuse where the battery comes into on the fuse block gets so hot it start to melt. Any further ideas?
