Black tank wiring

[Kircj]

I have 1989 Rockwood class C. My 3 sensor wires go into one wire that’s white with black stripe. It has came loose and I cannot find the other end to ur. This is not a ground because it’s already hooked up. I figure it is a power wire going to monitor. Ty for any help.

Welcome to the forum its a great place to get your questions answered. Your statement "it not a ground because its hooked up" doesn't make any sense. this does sound like the ground for the system if there are three wires into one. are the other tank sensors working?

[Kircj]

Yes other ones are working.

Let me te explain. The white is hooked to sensor and connected to frame, I would guess that’s ground. The other 3 sensors all have wires , there each connected to a sensor, then put together and a pigtail is added to them which I believe is supposed to be hot wire. But I can’t find other end coming from monitor.

What does your tank monitor display look like? Post a photo so we know what we're discussing. The manual for it may be on-line even as old as it is.
