Question about Cars & Trucks

3 Answers

I have an 86 dodge d100, 318. When the vehicle is running, I pull the lever for the headlights, and the fuseable link from the positive battery post to the alternato blows. I have a 40 amp fuse in the fuseable link. The headlights come on but the battery doesnt charge due to the blown fuse.

Using a 40 amp fuse instead of a FUSE LINK does not carry enough amps for alternator.--Install a proper FUSE LINK WIRE--CARQUEST carries them premade--If you are not sure how to do this, consult with a GOOD auto-electric shop.--ask around.

Replace the battery
or the alternator is producing AC and not DC ie its rectifier has failed

SOURCE: Fusible Links on 1972 Ford F 250 PU

follow the wire where you think the link may be, and and where the large bulge is, is where the link usually is, now the fuse is not usually non-replaceable, so you can go to a parts house and get an aftermarket fuse link that can easily be installed. take the voltage regulator with you and have it tested to insure it was not damaged.
also check all fuses in the fuse box. and the link on the main wire on the back of the alternator.

SOURCE: blows fuses

SOUNDS LIKE THE ALARM HORN IS SHORTED, CAUSING FUSE TO BLOW.
TRY UNPLUGGING ALARM HORN & SEE IF FUSE STILL BLOWS.
IF IT DOES NOT BLOW, REPLACE ALARM HORN.

1994 Dodge B250 runs battery down overnight put meter between post and battery pulled all fuses no change black wire fuseable link disconnected kills voltage but van wont start then new battery


It would seem as though you have a drain somewhere in the electrical system.

A faulty alternator can cause a battery to drain - sometimes - within minutes. It's the rectifier pack - the diodes in the back of the alternator which burn out.

Charge your battery and when parked up, disconnect the connector at the rear of the alternator. If the vehicle cranks ok the next morning you have to suspect the alternator.

If the problem persists you then obviously have a current drain somewhere else. As you have removed the fuses and it made no difference .. this suggest that the drain could be in the instrument cluster/dashboard.

The best option is to visit an auto electrician. He'll be able to identify the cause of the drain within minutes

If the fuseable link needs replaced where is it located


Fusible links connect to battery power, usually somewhere along the red (positive) battery cable. On some vehicles the links connect to the red cable at the starter post connection, lots of GM cars put the links there. Older Fords had the links connect to the battery cable at the starter relay on the passenger fender. The links have to connect to direct positive battery power somewhere, because they work independent of the key switch being on or off. They get power from the battery and not from the ignition switch. Think of your headlights: you can use them with or without the key. That is because the fusible link (if so equipped) for the headlights gets power right off the battery.

Do you have an aftermarket key fob for your vehicle? Often these remote controls are wired into the lights for convenience. This could be the cause of the problem. Some vehicles were also programmed from the factory to have day-time running lights. These are normally controlled from the key position. If so it is possible that you have a bad ignition switch which is not disconnecting the running lights in the off position.

Dodge pick up 1981 doesn't fire


At the positive battery post, you have a cable with a large and small wire. The large wire goes to the starter relay, the small goes to the fuse box and the key switch. The small wire has a fuseable link between the battery and fuse box.
Do you have power on that wire as it goes into the fuse box ? And are the fuses hot with the key on ?

Why have i lost all electrical power to my 1974 dodge tradesman van


With the battery connected, did you check the fuseable link which is the pigtail wire on the positive cable ?
If nothing works, it has to be a bad cable, bad connection, or one of the major fuseable links from the battery to the fuse box.

some times when the dimmer switch on the floor goes bad the headlights will cut out. Try replacing the dimmer switch and the headlights should come back on. My 84 dodge had that exact problem.

My 1998 Dodge Durango won't turn over and the car is getting no power anywhere, except for the headlights. The engine will crank but won't turn over. Any ideas? Everything worked fine until we had to...


Is the ground for the engine and the battery clean and working properly check at point of connection with test light to see if all grounds are OK and make sure no positive cable are bare and touching metal causing a ground fault and blowing fuse . check wires at battery and going to starter some times wires will burn through and touch other wires or metal causing a direct ground. good luck
