Aprilia Atlantic 500
Regulator / Rectifier replacement

Step 1….in the beginning……

Why are we doing this, anyhoo?........Like a lot of people are finding out, the first thing
that’ll indicate you’ve got a problem looming is an occasional
flash of the red EFI light on the dash.    Before you have a heart
attack about this, switch the onboard computer display to Voltage, and watch
for the next flash.  You’ll
likely see alternate spikes and drops in voltage.  My bike swung between 9.9 volts and
15.9volts……so the computer is trying to flag trouble before you
blow something expensive up, like the ECU…………

Better get started on the tools,
then…………

First, you’ll need access.
There are 4 screws to remove the body panel, and you’re only
removing one panel - the one holding the number plate/licence plate.

Once the 4 screws are removed – using a hex key, preferably a
ball-ended one, like Bondhus – the panel is
pulled straight back, with a small bit of manoeuvring at the sides, where there
are locating tabs.   Take your time !!

As you pull away the plastic, you will need to disconnect the small
white plastic connector on the RHS, which is for the number plate light, and a
small

Plastic/rubber tube from it’s clips on
the mudguard – this is the battery breather pipe.    Store the platic panel UP OFF THE GROUND – you’ll look a
right

ass if you walk on it and have to buy another
one……….!!

Here’s the location of
the 4 screws
