I have a '97 Ultra SPX with a temperature guage that only works if the wire connecting to the rail is just right. I've tried closing the connection more and adding a zip tie but it only works for a little bit then works its way lose again. I've heard this is a normal accurance on these. Does anyone have any tips or tricks to make this work all the time. I would like the guage to work since it is there but then again who knows if the dummy light is working!? thanks in advace.
