I have a 2004 nissan titan and today i unhooked the posititive terminal on the battery cleaned the battery terminal and the connector rehooked it up and started the truck and all is fine for about 3 seconds and then the instrument panel starts going crazy like the temp gauges go from normal to zero the slip light comes on the rpms go normal idle to zero and back up to normal along with a few other lights any ideas why

Wait, so is the instrument panel doing this after the truck is started or once the truck is turned off? If it happens when the truck turns off it is completely normal, just the computer resetting the gauges. If this happens while the truck is idling, you have a problem...

I start the truck and all guages n lights are normal then a few lights start coming on and tack and temp go from normal operating to zero then back to normal back n forth but truck is idling normally and on my scan guage all temps, voltage and rpms are consistent

2nd and and shifts back n forth from 2 n 3

When you took off the (+) you jostled the line from the alternator. The truck isn't getting consistent voltage. This happened to me in a Honda I used to have. Start the truck, disconnect the (+) terminal, and put a voltmeter on the line coming from the alternator. If the truck dies, your alternator is toast. If you get a constant reading I'm wrong. If it's jumpy you either have corrosion in your line, on the alternator stud, or your alternator is almost toast. Good luck!

I would suggest a second, thorough cleaning as well.
I was having similar issues with my gauge cluster after I took my truck to the dealer for a transmission fluid exchange...the tech did a courtesy battery terminal cleaning on my positive terminal.
That's when my gauge cluster started acting up. I totally took apart the positive battery terminal assembly and cleaned every bit of it as best I could with baking soda. All good now!

May or may not help your issue, but it's something free to try during your troubleshooting process.

Good luck!
