N64 RGB Mod, no blue color?

Hi.
I've been modding my first console ever, an NTSC N64. I get a picture using both composite and RGB, but there is no blue when I play games. I can only see red and green. Does this have something to do with my RGB cable? When I measure from the output of the video, to the input (using diode measurement), I get the same value across all 3 cables, so shouldn't that mean that it should work? Thanks in advance.

Edit: I forgot to add I'm using an SNES RGB cable which I ordered from consolegoods.co.uk, called: SNES/SFC/GC RGB Scart cable

Edit2: After searching the internet, it seems that an NTSC SNES cable should work, so there is probably something wrong with my modding anyway. Any ideas?

I have marked the points I use to measure on the following picture: http://oi61.tinypic.com/rihfo2.jpg

 

First, open up your SCART cable. Check and see what kind of components are inside. Is there a set of capacitors AND resistors, or only capacitors? Can you take a pic of the inside of the SCART connector? If there are resistors in the cable, you need to remove the resistors coming off the output of the THS7314 chip (shown in the pic), and connect the wire directly to the little PCB board.

The test you did is not really valid, check all your connections. Go from each wire to each connection on the small PCB board. Make sure those are all good too. With your meter set to measure resistance, you should get close to 0 ohms (less than 1). The output side, you should get a reading whatever the resistors you used are (probably 75 ohms).

 

Thanks for the reply. I just went back and checked, and apparently I had too many wires on top of eachother, so the blue signal couldn't get through. What a rookie mistake, but after all, I am a noob at this . Thanks anyway.

 

Great, glad you got it working!
