I think that's a server message.   Try this query:

        select cast(1 as money) as 'a' union select '2'

You should get:

Msg 257, Level 16, State 3
Implicit conversion from data type varchar to money is not allowed. Use
the
CONVERT function to run this query.

(The character value '2' is implicitly converted to the datatype (money)
established by the first part of the UNION.)

You said it's a "simple update" statement, indicating that somewhere
you're pointing quotes around a numeric value or storing a number in a
variable declared as char/varchar.  Stop doing that and you'll be OK.  ;-)

If you're binding to a character host variable, similar restrictions
apply.  

HTH.
