and trying to get a replacement. I thank you again for your help!!
If you're seeing 19.7 volts there must be an open circuit somewhere.
If the circuits were all complete, but the panel wasn't producing, then you'd just see battery
voltage, ie. around 12-13 volts.
Check the diodes too, using the ohms setting on the multimeter - there should be near zero resistance one way, and infinite the other. Faulty diodes are cheap
and easy to replace.
Don't assume the wires are intact inside the insulation
- I had a similar problem, and it was due to non-tinned core
wire being used and it had rotted out.
Also, you really should have a charge controller. If you're away from the boat for a few days you could end up with cooked batteries.
