Default Re: Couple of wiring questions.

Heres a pic of my new brake relay. I get 48v to the blue/white in back. 12v to the Blue in back. 12v to the green/white in front and nothing to the orange. Nothing changed when I press the brake.
Also see the connection between the orange and the Blue/white wire.

I wish I could get a dash wiring diagram.

Why don't we focus on making the car run before we worry about brake lights? The controller is essentially the brain of the car. With a bad controller, multiple circuits may not work. Step one needs to be making the car move.

Sounds good to me..

Is my MCOR reading from the previous post ok?

As I pressed the pedal down the Ω'age went up gradually, topping out at 19.75. I did set the meter at 20kΩ

The MCOR readings are not right, You did have the connector unplugged and measured at the MCOR pins themselves, right?

What was the resistance value across the MCOR (the one supposed to be around 7kΩ)?

The Yellow to Purple reading is off, was the value You posted in or just Ω?

Move the pedal up and down several times and take the readings again.

Also, I noticed that the Blue/White #12 (that goes to the solenoid), shows 6v, (key on) when I turn the key off, it jumps to 48V-

Seems like the Blue/White is acting backwards.

The MCOR is bad.

Readings on non-energized circuits can be unpredictable... Did you connect the dc converter to the key switch? If so it's capacitors can remain charged for a while after the key switch is off.

I agree with Sergio, the readings are wrong. However, the MCOR signal will not keep the vehicle from running. It will cause throttle fluctuation, but the solenoid should still close and cause the car to attempt to run if the internal micro switch in the MCOR is working.

I have a controller on the way, Do you think I should go ahead and order an MCOR?

I did connect the converter to the key. Is there a better location?

Yes it needs to be replaced if it's got improper readings. The converter turn on wire is fine hooked to the key switch.

Should I connect the controller and see what happens? Test the MCOR then see if I need to order one?
