mudduck Posted February 17, 2010 Share Posted February 17, 2010 Heading home from work yesterday, car was running great. Pulled out from a stop sign, ran up to about 50, everything was good, then nothing. No dummy lights, no ingnition, nothing. The only thing that works is the horn. Pull off the road, and check the main black fuse. Its done. Grabed a spare thinking it might have just been old and brittle, made sure that the ing was off and nothing was on, stuck it in the spades, and it turned red instantly and burned up. checked the spades with a voltmeter and had constant power. Now I don't know if that is normal. Ended up getting a tow. Checking things out today, I have continuity from the + side of the fuse to ground. Also have continuity from the ignition from inside the car. I have unpluged about every conection I could trying to isolate the problem area with no luck. I have the battery unhooked and the alt is out of the car, and I am still getting continuity from the same spots I was before. At this point I am lost. I am going to have the alt. checked tomarrow, as I have had an alt. cause this before a few years back. Am I heading in the right direction? I can figure most stuff out, but when it comes to electrical, anything much more than basic stuff, I start to get lost a little bit Link to comment Share on other sites More sharing options...
Uncle Ed Posted February 17, 2010 Share Posted February 17, 2010 Sounds like your following a good route for your trouble shooting, at least to me. One of the tools I'd use is an old two wire light socket with connectors or alligatter clips on the ends, that way when you loose the light you know you found the right connection ( less up and down). Just put in place of the link. Do you have a repair manual ? Also what year and model is your Roo? Ed Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 17, 2010 Share Posted February 17, 2010 Sounds like you have a dead short somewhere downstream of that black fusible link. Start pulling fuses till you lose the short on your meter. If that doesn't do it the short is on an unfused circuit (fusible link only) or before the fuse box. First thing - check the connector from the harness to the ignition switch. Those like to melt sometimes and then you can get a short as two connections touch when the plastic melts away.

mudduck Posted February 17, 2010 Author Share Posted February 17, 2010 Well, went and had the alt checked and it was bad. Kept tripping their machine. This is what was happening when this happened a few years back. Got another alt from the parts place down the street. I'm going to pull the fuses and see what happens before I put this thing back together. I want to be sure that it was just a bad alt, and nothing else fried.
