My son has a 94 Deville that has an electrical short. I disconnected the negative battery cable and put my test light between the cable and the post and it lights up, which tells me there's quite a bit of current going somewhere. We pulled each fuse in the trunk and engine bay without finding which circuit is the problem. We couldn't find the maxi fuses to try them. The owners manual says their next to the engine bay fuses, but it was getting late and we didn't have a light. Can someone tell me where to locate them. Anyother suggestions on this would be helpful.

Thanks,
Bob
