need guage help

[egp8111 7]

Guys,

 

I have simple ( or actually a simple minded) question.  I have an electric UMA water guage on my 582.  It reads 80 degrees when it it powered up.  Is that considered zero or is it just reading ambient temp.  I'm trying to determine if I have a cooling issue or a guage issue.  I've taken the sender out of the waterline and put it in some cold water and it still reads 80 degrees.  The cyl head temps and the egts are normal to low but the water temp is reading high (200+)

 

thanks,

You have a bad connection or a bad sender more than likely.  The gauge measures resistance and you seem to have alot of it   I would get a new sender and see if things go back to normal.  You can also put the sending unit in a pan of water and boil it (with the gauge hooked up) and see if it reads 220 when the water starts to boil..
