Disconnect battery from car, use wrench to remove hold down of link, remove link, install new link, tighten up hold down, reconnect battery.

Testimonial: "Charles. Thanks so much for your responses but I should have mentioned that I do not even know where the fusible link is. I know it's a wire but don't know where it actually is. I know it's somewhere behind the battery. Also is it actually connected to the alternator or starter. The garage mechanic just said I need an alternator to battery link. Thanks. I need to take an auto class or something. I'm glad for these forums."

SOURCE: Hyundai alternator has no output is there a fuse?

Is the regulator built into the Alternator on this vehicle??

If the regulator is messed up - it can keep the alternator from producing output.  I am not familiar with this particular vehicle.

Airframe and PowerPlant mechanic.  I am familiar with principles, and how stuff works...  Clarify with the 'parts house' what they mean by the alternator being OK - while producing 0 output.  A lot of vehicles now have the regulator built into the Alternator...

A Hanes or Chilton's book would probably be able to help, and since the car is only 5 years old - see if you can pick up a Factory Repair Manual, and diagnosis troubleshooting flow chart.  These items are worth gold in fixing specific vehicles.

You could also subscribe to: alldatadiy.com    This is another technical resource base.  Hope this helps.

And: Yes, there are fuses.  A fusible link would probably mean the car wouldn't run, and/or a direct bad short.  A fuse could have inadvertently blown - look around.  Get a book.  Electrical stuff needs a roadmap.

SOURCE: Charging light come on after alternator replaced

No fusible link, make sure the wires connected to the alternator are making good contact. If you installed a rebuilt alternator, it could be defective. Also check the voltage regulator

SOURCE: reversed jumper cables, blown fusible link?

Turn the key to run,truck in park,and jump the starter from the small wire to the large wire on the starter solinoid.If it starts,all is good and your fussible link is probably right.The fusable links are located in the engine compartment,under a cover on the firewall.

Charging system 89 corvette

Is the charge indicator light lit on the insturment cluster ? (battery symbol ) Did you check for B+ voltage on the bigger wire on the back of the alternator ? The S terminal in the connector should have B+ voltage ,as well as the F an L terminals . No battery voltage at any of these will cause it not to work . Do you know what a wiring diagram is ?

Is there a fusable link that would keep the alternator from charging battery in a 1991 chevy corsica

Yes, I believe that would be a fusible link, rather than a large fuse (maxi-fuse) used on later models. The fusible links will tie into the positive battery cable somewhere. If not at the battery, then look for them where the positive cable connects to the starter. A bad fusible link will look like some of the insulation melted, may have bumps and bulges where the fusible link blew out. To replace a link, you cut it out and solder in a new link of the same rating.

What guage wire for the black fusible link?

There should be 2 white wires coming from the alternator. There is a splice where it will go into 1 wire then into the fusible link. If the fusible link is not burned, simply match the gauge wire coming from it. You should never use anything smaller in diameter than 10 gauge wire for the charging system. If you want to replace the fusible link, you can run separate white wires from the alternator to the positive battery post with individual fuses or fusible links. I would recommend each wire have its own Maxi fuse holder with a fuse no less than 60 amps each.

1989 chevy k-1500 headlights taillights parkinglamps dome light and dash lights will not come on and not getting any power to the headlight switch. and have replaced headlight switch and relay and there's...

Usually the power feed to the headlight switch isn't fused. It will come from a fusible link under the hood. On the right side of the firewall there is a black plastic cover, under it are the fusible links. Check here for a possible blown one. I would also suspect the headlight switch may have originally caused it to blow if thats the case. If you have already replaced the headlight switch, replacing the fusible link should repair the lights. Make sure you replace the fusible link with the same gage wire and same length.

Put new battery in 89 corvette now will not turn over

THERE IS A NEUTRAL SAFETY SWITCH ON THE SHIFT LEVER, UNDER THE PLASTIC. THE PURPLE WIRE & OR THE YELLOW WIRE SHOULD HAVE POWER WHEN YOU TUN THE KEY TO START. THERE IS A ANTI THEFT MODULE BEHIND RIGHT SIDE OF DASH THAT MAY OR NOT BE A PROBLEM. THE TROUBLE MAY BE A BLOWN FUSIBLE LINK WIRE. THERE IS AT LEAST ONE AT THE STARTER, SOME AT THE POS. BATTERY TERM. SOME AT THE JUMP START JUNCTION. THESE THINGS ARE SHORT WIRES, THAT ACT AS FUSES. THEY ARE USUALLY THICK INSULATION, SMALL WIRE INSIDE. PULL ON THEM ONE AT A TIME IF THEY STRETCH OR COME APART THERE IS THE PROBLEM. REPAIR OR REPLACE AS NEEDED. I WOULD START WITH THE FUSIBLE LINK AT THE STARTER.

Battery is charged, when key turned nothing happens, and the headlights will not even come on. Almost appears that there is no power to the dash. Brand new battery and alternator.

try cleaning or replacing battery cables. any corrosion can degrade the voltage. check the wiring behind the fuse block also. (loose wires..) your chevy may also have a fusible link between the battery and the fuse block.
