Solar Diode?
I'm having dead battery problems and have not found the source. I suspect the diode could be bad from the solar trickle charger. I still have current off the solar panel (although 19v seems high) me...

IMPOSSIBLE. Flat out. Zero chance of error. Not draining multiple good batteries in 12 hours. Most of those panel diodes are 3-amperes and they will catch fire if they short direct and pass 10 amperes.
Start with the BASICS, assume NOTHING.
Charge and then TEST the batteries, professionally.
You have a drain, and guesswork may find it after many frustrating hours. You need to troubleshoot it. Disconnect the NEGATIVE terminal from the house battery bank. No negatives connected anywhere.
Clip the test light clamp onto the bare negative battery post
Jam the test light needle into the DISCONNECTED bunch of negative wires.
Does the light, light up? Sure it does. You have a battery drain.
Draw a diagram showing which goes where and remove all the TWELVE VOLT fuses from the fuse panel. All of them.
Go back to the light. Is it still lit? If yes, then wherever the draw is, it is not part of the converter panel fuse network.
If you found the test light dark, then ONE OR MORE of the circuits in the disconnected fuse panel is the culprit. Try them one at a time. If the light, lights, then you have found ONE of the draws. Try each circuit separately. You need to do this one circuit and one fuse at a time.
Enough for Step 1
