cnuts13 I just had the same nightcrawler problem. Check the 2 fuses under the playfield (not in the backbox) to see if they've blown. If they have you can try replacing them, but if they blow again straight away, it's probably an issue with blown transistors on the aux driver board (search this forum for it). I had to order a replacement board (part number 520-5325-00) and all was good once it was replaced.
I was advised by the distributor to check the nightcrawler coils, magnets and relays powered by the aux board for shorts before installation - but everything was good, so not sure what cause the aux board to blow (but it certainly had - when we tested the old board 2 of the transistors had gone).
