mikeshoup Posted June 19, 2006 Share Posted June 19, 2006 Walked out to my XT Turbo this morning, battery was dead as a door knob. Voltmeter registered 0.57V on it, so I was walking to school. I get home, have a friend help jumpstart it, and it ran. Then after about 20 seconds, start noticed some smoke come out from underneath the black fusible link. Turned the car off. The alternator was burning to the touch. Had the alternator tested at Checker, and it turned out fine. So, now I have to figure out the problem. Any ideas? I'm about to go through, and cut up the loom coming from the fusible link and look for shorts. Help! Quote Link to comment Share on other sites More sharing options...
fastenova Posted June 19, 2006 Share Posted June 19, 2006 These have an internal volt. reg, right? I'd say to disconnect your pos. batt. cable and use a multimeter and check the line going from your alt. output to the fusible link for continuity (Don't know WHICH fusible link it is, but should be one of the 3 or 4 you in the box there, or you could just check to the battery terminal too...). Also check the exciter line to the batt. That would tell you if the lines are good. Then check the same line to ground, and that would tell you if it's shorting on a ground line. After that checking the harness might be your only bet. You also might be able to use the voltmeter functionality with the battery hooked up to see if it's picking up any voltage with the motor not running and the ignition set to 'on'. 1 Quote Link to comment Share on other sites More sharing options...

I'm about to go through, and cut up the loom coming from the fusible link and look for shorts. Help! DO the simplest thing first. I suspect the altenator is shorted out. Disconnect the altenator, get a fully charged battery, and start the car. Make sure all the alt connections are wrapped in electricla tape. If You still have a problem, then you have your work cut out for you. nipper Quote Link to comment Share on other sites More sharing options...
