Parallax power supply noise model 555
The Parallax power supply converter has worked flawlessly for the last 7 seven years. Now when a light 12volt is on, you can hear a high pitch noise come out of it. Looked at some other sites said...

Do not pass go, do NOT collect $200.00 change out the POS Parallax with a PD to match your battery bank (more batteries, more amps). I have two 12v or two 6v GC (depending on what I get cheap) and I went with a 60 amp and it works great, recharges off the genny very fast.
One word of warning, check the output wires on the new converter before you install it, mine came already installed and they were not done right, clamp set screw was on the insulation, not the wire. Drove me nuts trying to figure out why, two years after I installed it, that it wasn't charging.
