Temp gauge not working.
Replaced sender, no change
Bought new voltage stabilizer from yesterday tractor but it's just a pass through. No voltage drop down to 10 volts like it should be.
Sent them a message about this and they sent me here.

Any advice will be much appreciated

Thanks
 
What are you using to measure the output of the voltage stabilizer? The output is supposed to be 12 volts, but it switches off and on rapidly, several times a second, so that the average output is lower, around 5 to 7 volts. You would need to use a meter that shows the average voltage over time to get an accurate reading, or look at it on an oscilloscope.

Are the gauges hooked to it? That will happen if theres no current
flowing through the device. The stabilizer, at least the original
versions, operated on a heating principle based on current flow. No
current flow, no heat.
 
If it actually switched several times/second, then you should be able to see an accurate average voltage
with most digital meters. However, most voltage stabilizers that I've looked at switch much slower, like one
time/second. That would drive most voltmeters nuts and it would make most people confused.

I simply watch the output with a test light and look for a flashing light.

ery close to one second.

1 I also have an issue with the vr sending too much voltage out. 16+ volts.
I'd bet this could affect the gauge/ voltage stabilizer problem.
2. If I use an analog multimeter to test the voltage, wouldn't I see the needle pulse as the voltage goes up and down?

Thanks to all for your help.

es. When my eyes were good, I could detect the small needle movement of gauges in an old Ford F-150 with that same voltage stabilizer.
