Default fishfinder

Hi, new to forum, so here's the question, front fishfinder wont turn on, new batteries, so I measured the voltage on the wires going to the fish finder, I get 12.8 volts, however as soon as I hit the power button while keeping the volt meter hooked up, the voltage disappears. Doesn't drop a few volts, just drops to below a volt. The wires are of the correct gage as this use to work once, and the same thing will happen if even I hook up a different fishfinder, any ideas?
Thanks in advance!

You have a very high impedance somewhere in your wiring, it's probably caused by a bad connection. Check and clean all connections from the battery to your sounder.

thank you, the wires from the front run directly to the battery with the 3 amp in-line fuse, I did clean them, but I'm going to put new ring terms on and see what happens, thanks for the reply,

With new batteries and good wiring direct has to be bad connection or corrosion.

I believe that to be the case, I actually had a similar issue before on another boat, I changed out the ring terms and all was well. I'll do that and post back, thank you
