lastss Posted September 8, 2015 Posted September 8, 2015 Anyone know what would cause a factory amp needle to turn/point down?? was working fine then next I notice its pointing towards the floor does move a little when load changes. Quote
stangeba Posted September 8, 2015 Posted September 8, 2015 I don't know if this can happen but it sounds like the needle came off (or almost did) the stem. My second hand of my clock did that (came off). Bruce Quote
monte70car Posted September 9, 2015 Posted September 9, 2015 Bob try to reset the gauge, I belive you use a triple a battery across the post. I had that issue on my original u14 cluster which I was able to fix by using the battery. Quote
lastss Posted September 9, 2015 Author Posted September 9, 2015 so you hook up a aaa battery to the back of gauge & just do a quick hit with the voltage to move the needle? Quote
monte70car Posted September 9, 2015 Posted September 9, 2015 Correct Bob, I also saw you post over on the Chevelle website. The way RichG said might work as well I know I used the triple a battery to reset my. Quote
lastss Posted September 9, 2015 Author Posted September 9, 2015 I wonder if U could un hook the battery terminals & do it that way? Quote
lastss Posted September 9, 2015 Author Posted September 9, 2015 Well didn't work at the battery, Ill try at the gauge. Maybe Bruce is correct the needle came loose. Thanks Bob Quote
lastss Posted September 9, 2015 Author Posted September 9, 2015 Update, Well its didn't work under the hood, However it did work directly at the gauge Hooray & Many Thanks to all its a neat trick that saves a lot of time/lobor Many Thanks Bob Quote
stangeba Posted September 9, 2015 Posted September 9, 2015 Learn something new all the time! Great that it worked, I had never heard of this trick. I wonder what causes this to happen? Did the car get hit by lightning? Quote
lastss Posted September 9, 2015 Author Posted September 9, 2015 No but in the process of tightening the ac lines The red wire on the horn relay got touched for just a second & later the amp was fine But a couple miles later it was noticed, Which could very well had registered such a large neg draw it caused it. Not sure, but don't want that to happen again. I thought I had already turn the quick battery shut off but A Senior Moment. as I didn't. OH Well. Quote
monte70car Posted September 10, 2015 Posted September 10, 2015 Bob if you like that trick If you or anyone else switch over to LED dash bulbs if you use a 9volt battery you can test the bulb before you put it back in the dash to make sure the voltage is going the right way. You can also use the same 9volt to apply juice though the PCB to turn the dash lights on. Quote
lastss Posted September 10, 2015 Author Posted September 10, 2015 now if I can only remember that. LOL senior Moments Quote
