Purge Pump

Post by Grant »

Hi,

Just changed the motor inside the purge pump. Can anyone tell me how the temperature sender connects to the pump, it is just via the relay with the 2, 2ap fuses?

Regards

Grant

Technically 3 fuses in the circuit.
Numbers:
29 - decel relay supply
30 - pump relay supply
31 - motor supply through pump relay

Motor supply to earth through temp switch. Obviously temp needs to be hot so just short temp switch lead to engine earth to test cold

It will. Turn key one position to see if stops.

What was issue?

It stopped after about 10mins, probably when the engine cooled down, seems to be functioning correctly after motor change
