Which thing is showing red (battery, which tank?, all?)
Why do you think the monitor is wrong?
Hi - I believe the monitor is wrong, since the light remains on all the time. On this model, the indicator lights only come on when sliding the "test" button.
For this model, there are four lights in a column; dual use; labeled for battery on one side and tanks on the other. It's used by sliding the black tab to tanks or batt, then sliding the "test" switch to engage. Separately on this model, there is a black switch for when testing tanks, to select between fresh, grey and black.
Thanks!
