2017 Pinnacle tank monitors
My panel has a series of very small, recessed buttons you push to check tank levels, batteries. Some work well, a couple don't. You have to push and push and wiggle around to get it to make contact and you will get the lights when it does, but often it just doesn't work. Is this a dirty contact, bad switch, can or should I pull the panel and try to clean something? Of course, the black tank is the main one that doesn't work.
