Subject: AW: Fuel Pump - Again !
Hello Stephane,
Hi all again !
I checked the fuel pump and it's ok. But I wonder if the relay which set
the pump on and off is working good. I checked the electrical schematic
(French - Revue Moto Technique) and did not understand exactly on what
the relay is based to set the pump on or off (perhaps on fuel consuption or ???).
Maybe some of you know this answer. it could help me going on my check.
The fuelpump works only when the fuelcutrelay is closed.
The fuelcutrelay is closed when there are enough 'pulses' from the ignition to the fuelcutrelay.
So only if the ignition is working (when the engine runs) the pump works.
The pump is not strong enough to pump against to much resistance (when the carburator is full).
In that case to 'motor' of the pump stops running until the resistance is less again.
Mranwhile the fuelcutrelay keeps giving the pump its voltage.
I hope you can use this info.
