popping fusible links(help)

[djj624]

Hey guys i posted down a few (fusible links). To start from the beginning my fan stopped working. After some research on votexbuicks i found it was the fusible link at the starter. I brought all the links up to a fuse panel so basically i can change a fuse up top rather than a link down low. The problem is i keep blowing the fuse/link for the fan, anybody have any ideas where i can look to see why it keeps blowing? When i pulled the links off the starter to move up top i noticed that one of the links were cut and arching off the starter wich i thought was the reason it popped in the first place but i guess not. Any clues?

Bad fan? Thats the first place I would look! And spring for that relocation kit I posted! You should not have to ever worry about replacing fusible links. They should not blow.

The fan works i jumped it and it turns on fine.

Ill have to dig up a schematic and see if there is anything else on that circut. Did you use a DVOM and read amp draw on the fan when you jumped it? It can work and still be bad, it can just draw too much current.

Well i checked the relay plug to see that the red wire has constant power and that the brown wire has key on power as per article on vortex. The brown key on works but i was getting no power to red wire. Once i hooked the links up i had power to the relay plug(red wire) until the fan kicked on for a sec and blew it out again. Tried another fuse same thing got power to the relay, fan kicked on and popped another one.

Id have to look at the schematic to make a decision. Id like to see how the delay relay ties into the circut your working on? How big of a fuse are you using?

Tried a 15 amp that blew the went to a 20 that blew.

Tried a 15 amp that blew the went to a 20 that blew.

use a dvom and see what the fan is drawing, those fuses may be too small.

What do the other fusible links connect to? I have 15amp fuses in all of them but only the one for the fan keeps blowing. I dont have a DVOM so i cant check what the fan is drawing.

Fans require more current than 20A.

I'd try a 40A fuse, or a 40A resettable circuit breaker or the properly sized new fusible link to protect that wiring.

Make sure you use a fuse holder that is rated to carry that current, not a cheesy parts store one a HD one with large gauge wiring to it.

Usually a car stereo shop would sell a good waterproof one you could use with a larger fuse.

Thanks for all the input guys. Tuns out it was to small of a fuse. Stuck a 30amp in and all is good.

Put in the relocater kit and be done!!!! then your not dealing with a bunch of hokey fuse holders that will be unreliable. Those links power your entire car, they need to be correct, I have a sneaky suspicion your going to find some of those other fuse values too small as well! This kit comes with the correct fusibles and a new starter cable, its a perfect fit and wont take more than 30-40 minutes to install. What gauge wires are going into your fuse holders?
