Yamaha Outboard 2 stroke oil transfer pump
Hi,
I've got an HPDI which no longer transfers oil from the boat tank into the engine tank, even if I operate the toggle switch. I can't hear any pumping. So I'm assuming that the pump has failed or isn't getting power. I get a remote alarm, so it seems the 'request' for oil is there.
Does anyone know the colours or the routing of the cabling? Does it go direct from the engine to the tank, or does it go via the remote? Is it a switched positive, or is it fed a permanent +ve & expect a closure to ground to operate?
Many thanks, S.
