Super weird SCT problem (SCT cant even help!)

If so then you better get a multimeter and check the voltage--if there's +12V between 4 & 16 and 5 & 16 the tuner should power up. Also, make sure there is 0.0V or close to it between pins 4 and 5.

ok so i use my test light and pin 1 is the only one getting power...maybe the connector is upside down and pin 1 is actually 16...so i go with that... and i get the meter out.
i test between the first pin (which i'm assuming is 16) and pin 4... i get LESS than 12 volts but not 0. I do the same thing to pin 5...and it says Overload...

How much "less than 12 volts" between pins 16 and 4?
Also, I don't understand the "Overload" reading at all--is your meter auto-ranging? If not are you certain it was set to an appropriate voltage range?
There should not be any more than 14.4V anywhere on that connector--even with the engine running at 6500 rpm...

Cliffy, this is a reply to old post, but please bear with me. I have an intermittent problem with the instrument panel on my 2003 GT convertible. From time to time the whole panel "zeros" (all the gauges go to zero), they may stay dead for 10 minutes or several days. The idiot lights still work however (traction control, abs etc). I suspect I have an intermittent ground problem at G204. However, I don't know where G204 attaches to the frame. You mention a possible issue with G204, do you know where it mounts to the frame? If so please shoot me back a response. Much appreciated.
