markhansenconquest Posted August 21, 2014 Author Report Share Posted August 21, 2014 u didn't under stand the question....not how many amps is the alt....how many amps will the fuseible link hold before burning up.... Link to comment Share on other sites More sharing options...
importwarrior Posted August 21, 2014 Report Share Posted August 21, 2014 (edited) this is the only thing i could find.from what i have read fusible links are not rated by gauge and amps.BUT your stock car uses an 8 gauge wire and a black fusible link 16 gauge for a 65 to 75 amp alternator. http://oi28.tinypic.com/vhyfxe.jpg http://www.whiteprod...ble-specs.shtml Edited August 21, 2014 by importwarrior Link to comment Share on other sites More sharing options...

Tim_C. Posted August 30, 2014 Report Share Posted August 30, 2014 Put a dead battery in it, jump start it, and see what amp fuse will hold then. What you are testing is how big a fuse is needed, but it depends on the amount the alternator is charging / load. Increase the load with headlights, heater, electric fans, stereo, wipers, etc... and more is demanded on the fuse. A dead (zero volts, but will accept a charge) battery, simulates worst case scenario and greatest load that wire will ever see with the present alternator. It will try to charge basically full fielded at 65-75 amps or so. Link to comment Share on other sites More sharing options...

markhansenconquest Posted September 1, 2014 Author Report Share Posted September 1, 2014 Thanks Tim C and speed racer ...I will try that later ...Need to replace trans seal and finish putting interrer back in.... Link to comment Share on other sites More sharing options...
BandY Posted September 3, 2014 Report Share Posted September 3, 2014 The reason for a certain rating is to protect whatever is down the line. Otherwise, just straight wire everything, and see what burns up, a year or two from now. Using a 100 amp alternator doesn't mean you would use a 100 amp protector. Some circuits are 10 amp, some 20. Like Tim_C says, in a WORSE case scenario, what is the total load? Maybe it would be wise to go 5 amps above that? Link to comment Share on other sites More sharing options...
markhansenconquest Posted September 5, 2014 Author Report Share Posted September 5, 2014 I spoke to SOME DIFFRENT PEOPLE and everyone said, I wouldn't go bigger than 25 AMPS...I M AT 20 amps so im going to stay there............... Link to comment Share on other sites More sharing options...
psu_Crash Posted September 6, 2014 Report Share Posted September 6, 2014 My advice is to stay at 20. 16AWG wire will not handle 20 amps continuously. Any bigger fuse and you run the risk of the wire it's connected to becoming the fuse. Link to comment Share on other sites More sharing options...
markhansenconquest Posted September 6, 2014 Author Report Share Posted September 6, 2014 (edited) Thanks psu crash for reply.

Shelby Posted September 6, 2014 Report Share Posted September 6, 2014 if you are doing the charge wire mod for an 86 you need to extend one power wire that was tied into the alt power wire , the 86 harness had one of the sub systems patched into the alt feed wire from the factory ,, in 87 up they ran this wire all the way to the main fuse link connector as for the alt to battery power feed I'd recommend an 80 amp fuse minimala 25 amp fuse is way too small Link to comment Share on other sites More sharing options...
