Can alternator charge two batteries?
You can run two batteries on the same alternator. Alternators protect against excessive current drain and aren’t affected by multiple batteries. The alternator registers these two batteries as a single large battery and charges them the same. The batteries self-regulate the amount of current they take as they charge.
Where is the fusible wire on an alternator?
The dark green wire is the fusible link. It is bonded (electrical splice 09) to the Black with gray stripe about one foot down the harness. Go look at the wire on the battery terminal of your alternator. What color is it? helpful?
What kind of Fuse is a fusible link?
Check the fusible link. A fusible link is just like any other car fuse, but instead of being plastic, it is a thin wire with a thick insulator.
Where is the positive cable on an alternator?
New alternator and new battery installed prior to symptoms described. have the same problem? The link is in the positive cable right near the battery terminal. Check the ASD relay as well. Here is the wiring diagrams for the alternator so you can see how the system works with a guide to test the wiring as well.
What is the wiring diagram for an alternator?
Left RED is main, right RED leads to PDC and that Dark Green (same color as my schematic says the fusible link A111 is) leads from PDC to the PCM. The bundle under the PDC between the PDC and PCM has the Red Main in it but NO FUSIBLE LINK.
What size fusible link?
A fusible link is similar to a fuse, it is a type of circuit protector. It is a length of wire typically 6 inches long and usually two gauge sizes smaller than the wire it is protecting. If excessive current runs through the circuit, the wire overheats and melts, breaking the circuit.
What is the fusible link in a car?
What Is the Fusible Link in a Car? Fuses. Fuses are the most common and numerous method of circuit protection in an automobile. Relays. Relays are used to activate a circuit that requires more current than can be provided by a switch. Circuit Breakers. Circuit breakers are used in applications that require a lot of current such as power seats and windows. Fusible Link.
What gauge wire for alternator?
Tuff Stuff recommends an 8-gauge wire for its 100-amp alternators, and a step up to a 6-gauge wire if the battery is in the trunk. A 140-amp unit should use a 6-gauge wire, and 4-gauge to the trunk.
What is a fusible link?
Fusible links include mechanical and electrical devices. A mechanical fusible link is a device consisting of two strips of metal soldered together with a fusible alloy that is designed to melt at a specific temperature, thus allowing the two pieces to separate.
