I have a few cars that have electrical problems and I am going to start to trouble shoot them Sunday. Neither of these cars has run in years so on the one I even dropped in a new engine but I know from the melted fuse box it had problems, Initial test shows the following symptoms Fuse 7 gets hot. (fuse box melted) I never had one do this on a car I had running so I have not looked for it yet but it also drains the battery from somewhere and I am willing to bet the two are related. I have put in a new fuse box an a new Rob Grady Ground wire in the relays. I have yet to put power to the car. On the other car the #1 fuse blows after the car starts for about 10 secs I am guessing that the wire that goes through the firewall may be shorting out somewhere in the engine but again I have not honestly looked for it. Rob helped me start the search and hopefully I can find it quickly. I will be useing a meter to determine current flow and the normal resistance checks. The car does start and run without blowing the fuse if I disconnect the Computer connection behind the drivers seat. Obviously screws up mixture but it starts and runs just fine. I am posting this since I have not seen it before in a working car and its probably easy to trace but this looks like a good one to share info on since I have 5 cars that I have redone that the #7 fuse has melted and the harness refurb seemed to fix it although I have yet to even look for where the problem was. Obviously a common problem. I usually redo the wire harnesses totally on the cars before I try to start them and whatever I am doing fixes it but I am interested in specifically locating the problem instead of doing a harness refurb. I figure its a loose connection or something. When I redo a harness I solder it together and the problems go away. New terminals help to. Ok here is one (actually two) for you diagnostic gurus Ken [Non-text portions of this message have been removed] To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
