    Anyone else have problems with voltage regulator

    I have 2006 Scarabeo 500 the dealer said to me that the voltage regulator is overcharging, did anyone else have this same problem?

    This is a link to another thread covering regulator problems. The guys that have the experience have covered this problem on other threads as well.
    Good luck.

    It is overcharging, it's charging back at a rate of 15.2 amps, which is why I guess my batttery needed to be replaced already.

    Hi magnet,
    Is it 15.2 amps, or 15.2 volts? Amprage is gooing to be dependant on how discharged the battery is, and whether or not there is a shorted cell in the battery. If it is 15.2 volts that indicates that the regulator is not doing its job. Charge voltage should always be smoewhere around 13.8 volts.

    Ride safe, Ride long.

    My AA 500 storage battery was wrong. This is my lucky. I have to buy an other (Banner 14Ah). It is more cheaper like an voltage regulator.
    Now the average charging voltage level is on 4000-5000 rpm 13 - 13.3V !!

    I tought that this was too low, so I checked the voltage level on the battery tap! I used a digital multimeter, which showed +1 Voltage than the board computer.

    I mean that the board computer cheat about 1 Volt. My regulator and my battery is perfect.

    Somebody has a "problem" with board computer like me..?

    Not the whole picture, exactly. Aprilia states in the manual:

    "Standard charge voltage: 13 15 V DC at 5000 rpm."

    That you're at 15.2 V (I'll assume you meant volts and not amps) means you're just a bit over spec, but if that reading is from your dash display, if it's like mine, it runs lower than actual by about 0.5V or so. So actually, you could be running as high as 15.7V or higher. As others have pointed out, looks like your regulator might be at fault. Check out the links they've provided for more info.

    Just change the OEM Aprilia/Piaggio/Ducati crap/pos regulator out to a new or low mileage newer Honda Unit (600-1000cc)from ebay for around $40 bucks, it takes about 30mins to remove/replace and you will have a much better unit , I did it about a year ago and have had zero issues since....

    If you can't source the ebay one, you can get one at Electrex in the U.K. Here's a clip from an email they sent to me earlier this year when I inquired about a regulator for my Scarabeo. Should be the same part for the AA.

    We can supply a replacement; we are out stock of the brown connector but you can use the connector from your original by unclipping the terminals. Price is 65.00 + shipping; please reply to this email if you wish to place an order.

    Well, now I see why the price is so low. The regulator's used and the seller's a salvage yard. As long as you know that going into it, no problem. Caveat emptor.

    It is also important to note that the Honda unit requires the wiring harness to be removed and replaced with the harness from the unit being removed from the Atlantic/Scarabeo. The Honda unit is not a 'plug and play' installation.
