this should be easy?
 

In the main fuse box,under the hood i have a space that say alt1.25-- went to toyota that said it was a fusible link i dont think so but cant verify it would someone look at their's and tell me if it's a wire or a 100amp relay u no the one's that look like a cube. It;s location is the left back side 2 relays set in front of it.:roflwtf:

Yup, early MKIII's had a wire-style fusible link and the later years have the more modern fusible link cube like you can find at the parts store. If I remember correctly, the newer style is interchangeable with the old style so it shouldn't be too difficult to replace.

:dance:thanks so much for your response.do you think that this shortin in and out would trigger my car, 87 supra turbo auto, to go into limp mode once the car got a little hot?

I replaced my wire-style fusible link with an 80A sealed-type. Direct fit. But I was chasing a charging problem. I doubt this wire would send your car into limp mode, it just handles to output from the alternator. Have you checked for codes yet? http://www.cygnusx1.net/Supra/Librar...aspx?S=FI&P=23
