wellcraft elite fuel gauge problem

[badbowtie]

I just bought a 1986 wellcraft elite 21 foot cuddy cabin. The fuel gauge reads empty. I have heard one time if it reads empty it is one thing if it reads full it is something else. I am not sure if it is just a loose wire or what. What are things I should try I really don't want to be out and run out of gas. Also does anybody know were I can locate a users manual for this boat Thanks.

if power to guages ground the pink wire on the sending unit if gauge reads full replace sending unit if not reading ground pink wire on back of gauge if gauge reads full you have bad wire if gauge reads empty replace the guage
