Did you zero the meter? Sometimes a low value resistor is shunted by a choke, and sometimes some residual voltage in the circuit will throw off a resistance reading. Try removing one lead of the resistor and checking again, and if it's OK, see if it is paralleled with another low resistance component. |

Try removing one lead of the resistor and checking again, and if it's OK, see if it is paralleled with another low resistance component. I did lift a lead, and it's still reading zero, like a short.??? it doesn't look like it's paralleled with another low resistance component. |

I had a outdoor IR light that radiated from the light into the house. I could follow the electrical line using my AM radio all the way to the circuit breaker panel. This became a problem when I installed an active antenna about 50ft from the light. My fix was to install a Corcom line filter near the light, The Corcom line filter may or may not have been over kill, but, it was in my junk box, so I used it. It did the job. After a house rebuild (hurricane) we installed 5 new outdoor light, I bought two different models at Lowes. brought them home and tested them with my AM radio, I picked the quiet one and bought 4 more for the house.

Some ferrite clamp-on filters might help if you can get at the power lines close to the source... If the junction box has enough room install a sheilded RFI filter like this: https://www.digikey.ca/en/products/filter/power-line-filter-modules/838 Select for current, voltage, etc and you will see suitable units starting around 10USD. I don't know your lines voltage or frequency so that too you have to plug in... John :-#)# -- (Please post followups or tech inquiries to the USENET newsgroup) John's Jukes Ltd.
