what hte heckk could cause this ? when am cranking engine,a nd before the engine fires up the needle pegs way past 220 and gets stuck there, until i push the needle to the right with finger, wire is not grounded out or it would not return to under 220 like it does when i unjam it. works fine after i knowck it down from being stuck every time. Id liek to figure this one out so i can put the overlay back on my instr panel lol

anyoen know what the heck is going on ?

thanks

 

The temp gauge wire (dark green) is grounded by the ign switch for a gauge full scale operational test, when the switch is in the start position. If you want to defeat the test, cut the dark green wire going to the ign switch on the steering column.

 

well that sounds like a retarded test, what engineer decided to do that ? id like ot have a littel chat with that person...

thanks !

 

ok that didnt change anything, i pulled the dk green wire out of the column harness flat connector and gauge still pegs to right when starting engine.. i checked wiring diagram and it does reflect the wire coming form ign to the sender and then to gauge, so hmm, why in the heck would it stil be pegging right ?

wierd.,, its haunted, has to be,,,

thanks

 

The dark green wire in the flat harness that runs down the column goes to the turn signal switch & is for the right rear turn signal. You need to access the dark green wire going to the ign switch, which is mounted on top on the column tube, near the floor board.

The gauge functional test is there to make sure the gauge will register full scale in the event the sensor were to read a high temperature (low resistance). Sounds like your gauge is defective, as it should not stick when @ full scale.

 

hmmm well that sucks,... hmmmm
now where in the fudge am i gonna find a gauge..

normally lt green and yellow run the stoplamps, must be different on camaros only ? gonna look in diagram for that one

thanks!

 

The green and yellow wires run the R & L turn / stop signal lamps in a single filament turn / stop lamp system. Third gens, however, have a two filament turn /stop signal lamp system, so the green & yellow wires are used exclusively for the R & L turn signal bulbs and another wire (blue) is used for the brake lights.

 

interesting,,,

i have a new problem, my tach is getting stuck alot more often lately... it used to be that when it first started up it would get stuck at about 2k,. and well now it doesnt unstick

maybe this is a dash ground problem ?

what ya think ?

thanks Tim

 

Could be. I'd pull the cluster & inspect it, the harness connectors, & the sockets on the rear of the cluster. Also verify that the grounds on the harness plugs are good (< 2 ohms to the chassis, or so).

 

lol sounds like im gonna be pulling the instr panel out soon for housecleaning hehe, might as well replace all bulbs and WD40 the electrical plugs and chekc out grounds and etc

thanks !

 

Your Temp gauge is NOT defective. Mine does this also. The trick is to pull the cluster and file the edge of the gauge. Thanks to less than stringent assembly tolerances, the outer edge of the lip on the gauge is just slightly too high, causing the needle to hang there. Just file that edge off a little and no more sticking.

 

My temp gauge was sticking to I pulled my dash apart and bent the tip of the needle so it would'nt get hung up on the lip of the dash so far it's been fine

 

dash is apart, its not hanging up on anything on the gauge, its like hanging up internally, hmmmmm.,,,,,


thanks
