Unless, of course, the relay contact points are bad. The point is a diagnostic test. Doesn't anyone ever emery file oxidized or pitted points any more?
If you are familiar with this type of "Isolator Relay" it is a sealed unit. There are no contacts to file like you would have on a home A/C Contactor type relay.
Here is a link to one.

That was the original question I asked. Is there a way to test these isolator relays without removing the circuit board since they are behind the circuit board. Only test that the manual shows is to listen for the click and check voltages when it is pulled in.
