Went to jump start my 89, after a few seconds the jumper cables began to smoke. I was not cranking on it and the switch was off, cause I was going to let charge, anyway is it a short in the battery, also now i have no dome light. It worked before I hooked them up, I also tried another set of cables but same issue.

you sure you hooked them up the right way? only time I have seen them smoke is by hooking them backwards or drawing too much current through a cheap set.
 
You put your thread in a forum specifically for people who have tuning questions about things like injectors, MAFs and aftermarket tuners such as Tweecer, Moates or Anderson PMS. Therefore you post will not been seen by people who may have an answer but do not visit the Tuner forum. Convertible top problems have nothing to do with tuning an engine.

My advice to you is to twofold:
1.) Send a PM to one of the moderators and have your thread moved to 5.0 Tech
2.) Next time you start a thread, think about where it goes. If you are new to Stangnet, please read the terms of service and give extra thought to where your new thread belongs. There is some help in the text below to help you find the best place to start your thread.

Tuning problems go in 5.0 Tuning, with specific emphasis on modifications to the injectors, MAF and computer, along with aftermarket tuners such as Tweecer, Moates or Anderson PMS.

General tech problems go in 5.0 Tech. Tech is for suspension, electrical, brakes, body, engine repair and general troubleshooting on the computer & trouble codes

Tall tales about your 5.0 Mustang, pictures of your 5.0 Mustang project and stories about your last trip to the race track go in 5.0 Talk.

Do this and you'll get the best answers quicker and not get lost in the maze of posts about everything but the type of problem you are having.


Having said that, here some help...

Batteries don't develop shorts, they just quit putting out enough voltage to to the job. Smoking jumper cables without cranking the engine points to a major short to ground of one of the wires connected to the battery distribution point on the starter solenoid. Or, as already stated, jumper cables hooked up backwards.

Start the troubleshooting by labeling all the wiring connected to battery distribution point on the starter solenoid. The disconnect them all, and reconnect one at a time and test by hooking up the jumper cables correctly. When you get smoke and sparks, the last wire connected is the source of the problem.

found the problem...I replaced the battery from my other vehicle and it started turning over without the key in the ignition. So the starter solinoid was stuck.. after starting it with the key it was fine and replaced the original battery, charged it up and no problems. Thanks for your help
 
THANKS for the diagram, (too bad it's under the wrong forum). According to the instructions that came with my new solenoid, on a Mustang that's wired right, the Battery and Starter cables are connected to the big terminals on the wrong side. But the solenoid does not seem to are which way the electrons are flowing. Thanks for eliminating my worry about the previous owner messing it up.
 
I had same problem last year.... battery was dead so teied jumping it with me escape... jumpers smoked and smoked... thought iit was bc cheapo cables. Went and got heavy duty truck jumping cables... still smoked... replaced battery and started and would continue to crank and crank even when key was off and out... had to repkace starter solonoid actually 6buy times over the course of 3 months...the last one i went directly to ford and bought one.... no problens in a year....
