Got a 99 GT Convert. I have no power to the OD switch on the T handle and no power to the ebrake switch. I have checked all the fuses under dash and under the hood , any ideas where else to check
No power to the two wires that go to the push button on the stick . Have checked to see if all is pulled in and tight , no problem there, ground looks and feels tight. I checked all fuses once I wlil check again when I get home. Thanks
Ok. If you have just measured the power between the to the 2 wires going directly to the transmission control switch (TCS), then you haven't really tested for power. Why? Because the TN/WH wire is the return wire back to the PCM and is NOT a ground. The test for power needs to be between the WH/LG wire a known good ground with the key on.
I don't really believe that it's truly possible to test a ground by just "looking at it". If you really want to know it will be necessary to perform an Ohm test back to battery negative or a voltage test between the device ground and battery ground. A low voltage indicates the ground is good.
