Hmm.. configs and routing tables might give a clue. My guess is that your serial line is still seen as the preferred route.
By the way, be aware that depending on the bandwidth of your serial link, and your configuration, the "extra" bandwidth of the ISDN may be more hindrance than help. I haven't played with this using EIGRP (I'm more familiar with OSPF), so the variance command may get around this, but if you have (say) a 512 kbps serial link, and you add a 64kbps ISDN channel, and you have equal cost routes across them... you suddenly have 128 kbps of effective bandwidth in total. Not pretty. i know EIGRP can do unequal load balancing - I don't think it's automatic though (I'm sure someone will correct me if I'm wrong).
