I would agree with getting a McGregorys manual (I think that's what they are) Check the wiring diagram and go from there. Check all of the dash circuits and make sure they haven't been tampered with. It sounds like it would be a fuse, as it stopped working when you turned on the indicators, but it could be other things as well. Check the back of the cluster for any hidden fuses, backed out pins, loose connections and earths and any burn marks from overloading a wire or circuit, etc. Try a new flasher relay (They are cheap). It's a little hard to diagnose over a forum, but give a few thing a go. Failing that, get an auto elec or mechanic to check it out. A previous owner could have possibly wired in something else or fiddled around. I have seen it before.
