MJF-1886 Loop (?? PROBLEM)

[Saint]

I have a MJF-1886 LOOP I use for listening to the hf frequency bands, I don't think it's working like it was when I bought the loop two years ago.
I was wondering how I would check the bias-t to see if it's working the way it should. Can someone walk me through how I would go about seeing if I have a problem with the bias-t. I don't want to go and order another bias-t for this antenna if there is nothing wrong with it. MJF sell the bias=t for 176.00 dollars US.

First off, diagnostics like these should start with you having a simple Volt ohm Meter (VOM). Once you have that you can measure the voltage coming out of the Bias_T, and the continuity of your coax and power cables. These are the places I would start.

If you have never replaced the coax - if it's not sealed properly the water will get into it - consider replacing that and properly waterproofing the connections to the loop

I have a Volt ohm Meter (VOM). But where do I do the probing with the black and red probs. never did this before, there is an in connection and an out connection.
