A Circuit That Shouldn't Be A Circuit....

[WallerZ]

Hi All,

 

Somehow, whilst fitting in my electrics, I have managed to fit what I can only think to be a circuit through the ground points. The high pressure fuel pump appears to keep running, even after the key is removed!! The only way to stop it is to remove the ground/negative wire from the pump or the negative from the battery (which when reconnected the pump doesn't continue like when reconnecting the pump ground/negative)

 

Anybody got any thoughts??

 

Cheers,

Zach

A latching relay controlling the HP pump?? And fault is in the relay coil circuit?

I'll try see if the LP pump does the same, couldn't hear over the HP pump, as they are wired into the same circuit.
