Fiat 500 Auto Box Dualogic.
Gearbox went into neutral and displayed transmission error AA man diagnosed low fluid in dualogic hydraulic system. AA man topped up system but this made no difference so car towed home.
First thing I did was check the fuses as there was no whirring noise when you open the drivers door. The car was blowing blowing the 40A Fuse when opening the door. When the pump was disconnected the fuse didn't blow so I presumed I had a faulty pump.
Extracted pump and tested it on a battery with a length of speaker wire (thin gauge cable) and the pump turned ?? Not as fast as I expected but it ran consistently at the same speed. Put my finger over the pumps hydraulic port to see what the pressure was like and the pump slowed right down to a stop quite quickly no real pressure. Is this a faulty pump? Should I use a heavy duty cable......
So attached the pump back on the car just the electrical connection no hydraulics and replaced the fuse. Opened the car door and nothing happened pump did not run and the fuse did not blow.
Does anybody know about how to test the pump ?
Why wont it run when disconnected ?
Any assistance much appreciated - too cold to carry on so stopping to take stock of the situation.
