SQLPS - Checking for a specific table

Question

I am trying to check for a table existence in each database.  Any ideas why this does not work?
Import-Module
"sqlps" -DisableNameChecking
$SQLServer
= "wobdslezberg2"
Set-Location
SQLSERVER:
$dbArray
= Get-ChildItem
-name -Exclude
"tempdb*",
"master*",
"model*",
"msdb*" |
Sort-Object
foreach ($DatabaseName
in $dbArray)
$instance =
$DatabaseName
#write-host  $instance
if (test-path
"SQLSERVER:\SQL\wobdslezberg2\DEFAULT\Databases\$instance\Tables\eConfig") {write-host
"exists"}
else {write-host
"not exists"}

I am trying to iterate through all the databases on the server and check for the existence of a specific table in each database. 
Actually that line does work fine because if I comment out the if test-path line, I get results as expected.  and I get list of tables like this
dbo.SRC04_TABLES
How do I put in the schema (dbo) in the test-path?
The test-path does not seem to work as I get this message
Test-Path : Cannot retrieve the dynamic parameters for the cmdlet. SQL Server PowerShell provider error: The number of keys specified does not match the number of keys required to address this object. The number of keys required are: Name.
