1970 challenger fusible link

[simpson]

hi I was wondering if anybody can help me,i fried the fusible link on my challenger ,i have put A 30 amp fuse in the wiring,where the fuseble link was,i have,nt driven the car yet but it starts and runs ok,will the fuse do the same job as the fuseble link?,the fusible link itself has A number 16 on A little rubber tag,I assume thats the thickness of the wire,my challenger is all standard as far as electricals go , any thoughts would be appreciated    thanks

Hi simpson..I can't help you with your question but you are on the rigth place most of the members know a lot about electrical problems..I only whant to say WELCOME to the site

You should be ok, you might want to buy a "slow Blow" fuse.  Problem with standard fuses is they break as soon as the current is exceeded.  If there is a current spike for any reason (past 30A) the fuse will blow.  The fusible link is a smaller diameter wire (16g in this case) that will fry when current exceeds the wire's capability.

Slow blow fuses will handle momentary spikes before blowing.  Worst case carry a couple extra fuses so you don't get stranded somewhere.

No problem using the standard fuse, you won't damage anything.  It will actually protect the car's wiring better than the fusible link.

The fuseable link will take more current for a longer time which heat builds up.  The fuse will blow quicker is all.  A slow blow is basically the same as a fuseable link in that it will take the surges of current better.  That is why they use a fuseable link so they will not blow as quickly.    that the system would be protected better in the long run.  Usually when the fuseable link burns there is really something shorted out.

thanks for your advice katfish,i,ve never heard of slow blow fuses,i have A spare 30 amp fuse,may be i should try put everything on at the same time headlights etc,rev the engine up to about 3000 rpm get as much current load as possible and see if it blows,thanks for the welcome black 340 we need to help eachother to keep our old mopars alive   cheers

I suggest you get yourself a new fuseable link instead of the fuse.  Like 426HEMI said, it will take current spikes better than a fuse.  You should be able to get a length of the fuseable link at any autoparts store, and fix it back to the way it was designed to work.

A fusible link is nothing more than a smaller gauge wire and I agree with everyone that the fuse will probably be more of a nuisance because it's more susceptible to blowing, so carry a few spares with you if you keep it.

 It's a good idea to solder the connections and use some black shrink wrap insulation to help it look original. You can even double it up the get a thicker appearance.

thanks for all your advice ,i ,m going to put A fusible link back in ,I managed to get some fusible link wire which has 16 ga on it same as the old one so should do the same job
