Relays only have coils inside most of the time. and resistance in these coils is not relevant to diagnosing them. The contacts do develop resistance when they go bad, but there is no standard for a any given resistance. The bestway to check a relay is to energize the coil with 12V. Then checking the resistance to the contact. There should not be any resistance at all. If there is any then the contact is bad.

Possible problem with the alternator not putting out enough voltage. I had the same problem with my 2002 XC70, putting in a new alternator fixed it. I used a local mechanic who I found on the car talk web-site. Low Cost Volvo parts can be purchased at FCP Groton.
