98 cali 1100 FI regulator replacement

    The regulator on my 98 California 1100 fuel injected burnt up (melted wiring from a case of lost insulation on the charging wires coming in contact with the frame.
    I ordered a replacement regulator and while waiting for the part, downloaded a color coded wiring diagram.
    Since this is a Ducati charging system I ordered the Guzzi part number for the Ducati regulator.
    My problem is that looking at the wiring schematic and the regulator wire colors, every thing is just fine until I get to the Green wire. The paperwork states that the green is for Earth or ground, but the Guzzi wiring diagram states or shows it going to either the headlight relay, or rear stop light switch/ horn and turn signal switch.

    Since I have a regulator that was replaced previous to my purchase of the bike, I have no clue where the burnt connectors went into the wiring harness.

    Any help before I burn the bike down hooking it up to the wrong item? :eek: :eek:

    Re: 98 cali 1100 FI regulator replacemen

    Since you are in the US, I presume your bike has the P8 ECU. In which case the schematic for the 1996 1100i on this page should be correct. https://www.guzzitech.com/guzzi007/sportissimo.html

    I also looked at the 1998 schematic. Neither schematic shows a green wire from the regulator/rectifier. Where did you get the unit you are trying to connect? Also in both schematics, the regulator/rectifier grounds via its mount to the chassis.

    Thank you John.
    I am including the item description from Euroelectrics. Their site is easily accessed and they have pictures to explain the wiring of the regulator. I couldn't get pictures on here, newbee right? Hope this helps.

    I went to the Euro Motoelectrics site. Looks like you bypass the bikes harness completely except for the connection to the idiot light. The red wire with fuse connects to Battery positive. Connect the green to the engine for a good ground. I'd use a good connection to one of the timing cover Allen screws. The white is to the idiot light connection and the two yellow to the stator connections. By bypassing the harness you should get little voltage loss.

    Sorry, I see this as a super old post, but I’m also there with similar questions. I had my original rectifier melt down, and bought a new one. My old one has a free ground, the new one doesn’t. Does my new one just rely on the mounting for ground? Any leads on how to proceed? (1999 Moto Guzzi V11 Bassa) The new one is to the left in the picture.
    Thanks!!!

    Just add a ground wire from the engine case (one of the screws to the timing cover) to the mounting bolt for the regulator and you should be fine.

    Do you think I should I wire in another fuse on the power (double red) lead? The original looked like it melted without popping the fuse. Ha!

    It probably got hot due to a dirty connection. Just clean everything up and you should be fine.

    And the mystery continues. I replaced my rectifier, and I’m still getting a power draw from it. Would the alternator be the next step?

    Disconnect the alternator. If you don't have the power draw, there is your answer. How much amperage are you reading for a power drain?

    This is getting really weird. I tried 4ways:
    ECU and rectifier plugged in.
    ECU only.
    Rectifier only.
    Rectifier only, alternator unplugged.

    I get higher reads when I switch the black to red wire feed on my meter via versa? I am reading in line with the negative from the bike, and to the negative post on the battery. Electrical is not my friend.

    Looking at your meter, you have the test leads in the "com" and "input", but you have the dial set to "A". I believe those sockets are for Volts and ohms, in fact everything except Amps, you need to move the Red lead over to the socket marked "A" (for amps).
    Be careful with the setting on A as its puts a very low impedance across the circuit unlike the voltage range, so don't put it across the battery or you will blow a fuse or damage the meter.
    good luck, Kevin

    Thank you, I’ll give it a try today. I looked for a good instructional resource for this particular meter, and couldn’t find a clear one.
