Help !! I´ve been following many of the threads on similar problems and hoped that I had already sorted out my 1989 africa twin 650 problems. But no.
One cylinder cuts out with the rpm counter then two minutes later the bike grinds to a halt. A few minutes later it re starts on a single cylinder then the second kicks in before it dies again. Some fuel still in the tank.
So due to the rpm counter cutting out I first made sure that I have 2 good cdi s.
So then I have the same problem with the engine stopping but without the rpm counter and single cylinder issues. So I go to the fuel pump figuring this could be a combination of two problems at the same time.
I take out the fuel pump and connect it direct to the battery. No life so I buy a new HUCO pump and install it.
Everything works great except the rpm counter has cut out again but both cylinders are working fine!
Then the bike cuts out again. I check the Huco pump that I have installed by connecting it direct to the battery. It works with no problem so I check the power supply to the pump and find that there is no current going to the pump. So I have infact been running on gravity.
Can someone explain what controls the power to the fuel pump and how the fuel pump regulates itself. Does the power only come to the fuel pump if the reserve tank sensors work. My fuel level lights haven t worked for some years now. Are they connected to the fuel pump power supply. Is there a relay that cuts the electric supply to the fuel pump?
I m not too bother about my rpm counter not working so long as the two cylinders are running fine. This could just be an old counter with a dodgy connection that I m not going to try to find unless it is connected to the problem of my engine cutting out.
HELP, HELP !
