level indicator has stopped working for one of my tanks
- showing max even when the tank is disconnected. Also if I swap the tank cables
, the same indicator is bad. So... the small electronic card on the back of the 201 panel seems to be faulty.
I want to try and fix or replace this card, but can't find any info on it.
Can anyone here help me on this? Anything might help, e.g. an electronic schematic of the card, a photo
of the back side of the card (which I can't dismantle due to a soldered connector on that side), or a card replacement source.
Thanks for any help you can offer.
