Ok,i have fitted a Autometer temp gauge (one with black screen, that then all lights up when ign on)the sender has 2 wires one black(sheathed)one white(sheathed)wired all in and left black till last(intructions a tad vague but i assumed white wire went to S(sender)on gauge)black to earth,so with ign on i ran a test on black wire before fixing to body,it showed 4 to 5v through it :confused: ,so without it connected and engine running the gauge will not move up(gauge does light up and needle moves to say start point when power on)am bit worried to actualy connect the black wire to car body,anyone else fitted a sender with two wires from it or can shed some light on this,cheers,Tony :)

 

ps,sorry if it seems question a tad muddled ,bloody knackerd.

yep black wire to ground on sender white to s on gauge

yep black wire to ground on sender white to s on gauge

 

 

Cheers mare,but any idea why it would give out 5v,is this to somehow send a signal as in a loop to sender?.

 

Tony

I think with mine I ran white to s on the guage and black to earth on the car not to the guage.

yep cos the gauge acts like a resistor so it will show some voltage

grond the sender any where u can on engine

Cheers lads, will do it tommoro and let you know. :cool:

mate i have this gauge and thats the right way to do it, remember the sender has to be earthed as well.

Ok chaps,all working,very nice gauge when lit up,went for a blast,about half an hour,plenty of WOT and temp not goes above 70c :dance: , happy that i no longer have to keep looking at the crap OEM gauge just in case it darts to top without warning :D

 

 

Tony :cool:
