Connecting Fan 2 Wiring to Auto/On/Off Switch

AI Thread Summary
To connect FAN 2 wiring to the AUTO/ON/OFF switch for manual activation, A10 should be connected to the AUTO side of the switch, while the ground should go to the ON side. The fan relays are grounded by the PCM, with A10 and A11 functioning as switches to connect the relays to the negative side of the source. The feed lead should be connected to the negative side of the coil. This setup appears to be correct for the desired functionality. Proper wiring will enable manual control of the fan as intended.

What I'm tring to do is connect FAN 2 Wiring (673 DKBLU 2nd picture top diagram) to
The Auto pole of the AUTO/ON/OFF switch so I can manually activate the FAN if needed.

I'm a little confused since in the 2nd pic, I don't see a Negative side to the coil on the relay.
Can/will this work?
 
Engineering news on Phys.org
The fan relays are "grounded" by the PCM. In other words, A10 and A11 are working like switches that connect the relays to the negative side of your source.
 
So...
I would connect:
A10 to the AUTO side of the switch
Ground to the ON side of the switch
The feed lead to the Negative side of the Coil

Is this correct?
 
Yes. That's the way it looks to me.
 

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
