When I apply power and ground the fans kick on without the remote.

What's the PC# on the board?

 

[mnhiphop101]

4759-A

 

[Perry Babin]

Closest I have.

Do you have any voltage on the remote terminal (with nothing connected to it)?

Do you have any drive on the PS FETs?

 

[mnhiphop101]

No there is not 12v on the remote

There is drive on the ps but the output section isn't kicking on and all 3 lights stay on.

 

[Perry Babin]

Is there ANY voltage on the remote terminal?

Lift/remove D3. Does it still come on without remote?

 

[mnhiphop101]

No voltage on the remote.

Lifting D3 made no difference

 

[Perry Babin]

What's the DC voltage on the cathode of D4?

 

[mnhiphop101]

Should I put D3 back in for this?

 

[mnhiphop101]

.531v

I just noticed im not getting any power on the red wire

 

[Perry Babin]

You have to measure the voltage across the red and blue wires.

Post the DC voltage on all terminals of the SG3526. Copy and paste the following list and fill in the blanks.

Should I be powering it up for this with remote and power?

 

[Perry Babin]

No remote.

Oops thats with remote

 

[Perry Babin]

The problem is without the remote voltage applied. That's the condition I need for the voltages to be useful.

 

[mnhiphop101]

Ok here is without the remote

[Perry Babin]

Was the fan running when you took those readings?

 

[mnhiphop101]

Yes

 

[mnhiphop101]

Idk if this helps
