Electrical problem - short somewhere
I'm just getting ready to fire up my new engine but when I connect the battery there is an obvious short somewhere - the terminals try to weld themselves to the battery. This is an old car (1972 XA Falcon) and has had alot of dodgy work done on it in the past, which I'm slowly tidying up. The wiring is an absolute mess and there are bugger all fuses. From what I can tell all of the positive wiring goes through the starter motor as the big starter + cable is the only cable that goes to the battery. How can I locate the short? Is it possible I stuffed up the wiring for the alternator and this is what's causing it? Please help me, I'm desperate! Really want this thing going today as it's my ride to work tomorrow!
Edit- Just found that if I unplug the alternator (I set up a plug for the 3 wires to the alt for ease of removal/fitting) then the short doesn't occur - what else comes off the alt wiring?
