Subject: Fuel pump: Final solution works! ;-)


Hi,

so after a few days of beta-testing I can tell you folx: The fuel pump 
starter relay works. [please calm down the applause]. ;-)

How was it done?

I bought the Delay on/off timer electronic kit (Verzögerungs-Ein-Aus-
Schalter Bausatz) of Conrad Electronic (for Phone Orders call 01805/312111 
24h Service from inside Germany), the Part Number is 19 59 01-99, it 
costs 20,95 DM plus expenses.

The kit comes with a very detailed description, which helps any experienced 
electronician to easily and quickly build up the device. I soldered it all 
together, configured it for delay off for 5 seconds and wrapped the whole 
thing with duct tape tightly. I fixed three cables for connection to the @ 
fuel cut relay. Then I put it all in a small plastic box and glued the two 
halfs of the box together with pattex hot glue (Heißkleber), so that it all 
becomes water resistant. I fixed the box behind the left side plastic thing 
(linke Seitenabdeckung) right behind the fuel cut relay and the CDI unit, 
about 1 cm away from the lock, which unlocks the seat.

After that I connected the three cables: Ground to the green cable of the 
CDI unit, plus 12V to the red/black cable of the @'s fuel cut relay and the 
third cable (output of timer delay relay) to the black/blue cable of the 
fuel cut relay.

Now if I switch on the ignition, the fuel pump runs for five seconds, so 
that I can start my @ with a full running fuel pump. It starts after three 
days in the rain, as if I would have been ridden a few hours ago. ;-)))

The little box has a red LED light mounted, which I can see when I'm 
looking from the bottom side of the @ under the left side of it's seat. ;-) 
So it's easy to check, if that thing still does work, because of the 
vibrations of the bike it could be, that electronics fail after a certain 
time... Until now (about 400 km) it's still working. ;-)

take care - Marcello.
