Gelignite?

 

.........or a less drastic although more mundane approach. If completely rounded, file flats across parallel sides until a smaller size wrench will fit.

Tapping on the end of the wrench with a hammer to shock the nut free is often more effective than applying ever increasing pressure.

If you've got a welder and can get to the b*st*rd welding something you can get a grip on to the head is very effective also - the thermal shock often cracks the threads loose like Graham's hammering technique.
(sorry, Graham, no slight on your hammering technique implied here)

 

OK guys, I need an easy way to get the alternator out. I've read that possibly removing the the tire and fender well plastic and manipulating it out that way. Any ideas?

The last post - good news re the aircon compressor

I'm sure Thermo wouldn't mind a pm if you need more info

 

Well, I guess Ineed to go to Vegas! I removed the alternator by dropping the AC compressor, put the new one in, hooked everything back up, attached the battery and turned the key. Lucky me it started! It do blow the jaguar voice and radio fuses but everything else works! The only thing is that the ac fan blower cycles from to low and back to high. Any suggestions? Thanks everyone for helping me through this extremely rough project!

 

Result.

If the AC is the only issue, could be best to start a new thread with that specific question. It would get wider input from members who may not have been following your narrow escape from disaster.
Getting very close to a happy ending on this one.

okstate, do you have the radio with the integrated A/C controls or do you have the basic radio with the separate A/C controls? That will help eliminate some potential parts. If it is the combined radio-A/C, then you may have hurt that with a surge and the fix may be simply getting a new radio to put in there. But, before you start replacing parts, lets get some more information so we can go in knowing exactly what we are dealing with here.

 

It certainly could have been a lot worse, glad you're nearly sorted.

 

I did the same thing this past weekend. I put the negative on the positive. It blew 7 fuses and fried my alternator.

 

Isn't it reassuring to know that that $200 alternator will valiantly sacrifice itself to protect that $8 fusible link?

I've cleaned up after a few of these...not on a Jag yet, but most radios and controllers have a circuit known as a 'crowbar' across their power supply leads internally. If the device is 'on' when the leads are hooked up backwards, it should blow the fuse. Sometimes, the crowbar diode itself will pop, but they can generally be easily replaced by any competent electronics tech.

It is actually only the diode bridge and regulator that waffle on the alternator, as well; replace them on the one you removes, and you have a spare for the price of the core charge and bridge.
