solidbob Posted August 6, 2009 Share Posted August 6, 2009 So I've been following threads for changing the regulator for the gas and temp gauges, as mine do not work in my 92 Pathfinder. I called the Nissan dealership and they can't find nor have they heard of this part. I explained it to him, what it does, looks like and even the part # from one of the PDFs another poster provided us about how to change it. Is there a certain way to ask for this? I asked for the voltage regulator for the gas/temp gauges that is located behind the instrument cluster. I'll try radio shack as i heard it's a pretty generic part but I don't really want to tear my dash apart if I get the wrong thing. Thanks Link to comment Share on other sites More sharing options...
MY1PATH Posted August 6, 2009 Share Posted August 6, 2009 (edited) my mechanical cluster does not have the electronic regulator. There is an analog 'pulse regulator' (as I call it) inside the cluster. it is a flat spring with a wire arround it that touches set screw. as electricity goes thru the wire it moves away from the set screw. when Not contacting, the fuel and temp go down & it relaxed till it touches the set screw. once contacting the guages go up and it moves away. It does this so frequently that your guages hold thier position rather than go up and down. run some 400 grit between the screw and spring and trun the screw clockwise to increase callibration.

NissanNut Posted August 6, 2009 Share Posted August 6, 2009 (edited) 7808 its a 8 volt regulator. There $5 on ebay for 20. $1.49 each http://cgi.ebay.com/7808-VOLTAGE-REGULATOR...p3286.m20.l1116 Edited August 11, 2009 by NissanNut Link to comment Share on other sites More sharing options...
solidbob Posted August 10, 2009 Author Share Posted August 10, 2009 So I talked to the Nissan dealership a second time, I gave him the 25020 part number, told him where it was located on the instrument cluster and what it does, he said he has it listed as some kind of voltage amp and that it costs $120! He described it as the little silver box on the back with the three wires also. I think I will go the Radio Shack route and do the soldering job that is posted somewhere here, that costs 2 dollars. If that doesn't work I may look for one in a junk yard but there is no way I'm paying $120 for that part. Not even positive it is the voltage regulator but for 2 bucks I can't afford not to try it. I'm thinking it is because no matter how much I drive my temp gauge also never moves. Also, does anyone know an easy way to disable that annoying chime when the driver's door is open? That drives me crazy. Thanks for all the input. WIth all the great info on here it almost looks like I know what I'm doing. Link to comment Share on other sites More sharing options...

This is the real part number 24866-54A00 Courtesy uses bogus numbers for some reason. It fits truck and pathys 93 and older. Also the B12 (sentra) 1/86 and newer uses the same part.
