[hypoxia]

Nice description Jim and good to know what's needed and available from Newell.

I've had my coach for about 16 months and the black tank sensor always reads high (double) of the actual tank level except when empty.  I re-calibrated several times via the Silverleaf panel and that didn't help.  I'll soon be replacing as you did.

Here's the Silverleaf Troubleshooting Guide in case you or anyone needs it. The sensor cost is 0.2 Newell Units delivered.
