1997 Vulcan 750 radiator fan stuck on 24/7

Desperate need for help! This is from a Yahoo forum I am getting help in...

Ok..good info. When it first started the bike had been sitting for
like 12 hours, so it was totally cool. I heard clicking sounds so I
took off the seat and it sounded like a relay was freaking out. Then
later on, I pulled the fan switch wire and the noise was still
there. So then it sounds like a relay has maybe gone bad.

Now the next question...which relay controls the fan?

Also kind of wondering if I just leave the fan disconnected if I will
be ok, or if it will overheat very quickly? I mean I would assume
that much of the cooling comes from the air outside, and not the
actual fan itself.

Thanks again for any help with this.

Ok..so nobody replied here but I got my issue fixed. Ended up being the fuse box is where the fan relay is, which happens to be right below where my POS wet battery is. Anyways when I took the fuse box apart, it had battery acid all inside and was all messed up. I cleaned the PCB with alcohol and resoldered many of the connections.

That took care of my problem...

So get a MF battery and you wont have to sweat this stuff..
