Could someone help the novice!!
I am working on estimatic both structural and measurement parameter using
LISREL. I used 19 indicators of 6 latent varible, three of which are
eta's (endogenous) and the other three are ksi's (exogenous). 

Problem :
In estimating this model I get negative beta coefficients where i expected
positive ones. Some one suggested that I could be have a mulcolinearity
problem. How do I test for it in LISREL? How do I resolve it short of 
eliminating one of the varibales from the model? 
e-mails appreciated.
