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 '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
