12v electrical

I lost some 12v power to a circuit I checked everywhere tore the bed apart on the scamper. After a lot of checking and no results I couldn't belive it so I went to the battery no 12v reading on my meter but had lights in the trailer.

after looking at the meter I had it turned backwards that is about incompetent!

now I am busily tracing my line matter of fact now found the problem and will be fixing it tomorrow!

fixed

well the 12v circuit is fixed for some reason a diode light would snap on and go off so I had to go to another wiring set up.

12v wiring is strange at times. very hard on a guy with recent back surgery but its done now!!

So I assume you are using the simple method of a light on a wire to test if you have power. And this light is an LED, or you replaced with with an LED.

Do your self a favor and pick up one of these.



harbor freight has them often on sale for 4.99 or even free. You can also pick them up on Amazon. You can read the true voltage reading of the battery, if you connect the leads backwards it just reads the voltage as negative (but that does not matter). You can check current draw (put the leads in line with the circuit). Everyone should have one in their tool kit.

1500 has the answer.
You can not connect it backward because if you do it says -12. If correct says 12.

I think you are on the right track to get out your meter.

Outside lights often develop poor connections since most of these fixtures don't keep out water very well, especially at 60 mph. Taking off the lens and polishing the contacts and adding a bit of dielectric grease (or Vaseline) makes it all better. But, 5 at a time are more likely some kinda fault in the wiring. Time to explore with your meter as you say.

Good luck, john
