Check your fuses; 20A and greater. If you are lucky you may not have damaged anything else. The starter is never fused but the starter solenoid very well could be.
When working on anything electrical, always remove first, and at a minimum the negative battery cable. This kind of problem doesn't need to happen only to save 5 minutes removing and reattaching the cable.

The small wire from the ignition switch goes to the small post on the starter solenoid. The large wire from the battery goes to the large post on the starter solenoid.

My Nissan maxima has 5 wires on ignition switch. how do I hotwire them to make it crank?

5 wires? I can't remember what the fifth wire would be, but you have a power-in wire - white with black stripe. The blue wire is an accessory wire- don't need that. To crank the engine without starting it, you would touch the power wire (white/black) to the start wire-the yellow with black stripe. That would engage the starter.

If you want to wire it to run, you tie the white/black power wire to the run or ignition wire-this is a black wire with white stripe. With those together, your dash gauges and warning lights will be on-the ignition system is ON. Then if you touch the yellow/black (start wire) to the power wire that is tied with the ignition wire, the engine should crank over and start.

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.

My1987 nissan pickup altrnatorwill not pull a charge, there is black wire connection that is under the boot. my black wire is just hanging there and not connected to anything but the alternator. where does...

Ground (almost always the black wire). Locate three or four connections on the alternator, depending on the type. One wired connection is black; another red; and the other can be blue, yellow, green and brown. The red and black wires are the main electrical connections. The others go to your ignition warning light system and voltage regulator.

Ensure the red wire is tightly connected to the alternator terminal. It usually is attached by a bolt. Move the wire to see whether it's loose; there shouldn't be any movement. If the wire is loose, tighten the nut using a suitably sized wrench.

Ensure the black wire is securely attached. It usually is connected to the alternator terminal using a bolt. Check whether the wire is loose; it should not move. If it does, tighten the nut using a wrench.

Hope helps.

1. Check the voltage on the White/Red wire at the 2-pin connector on the alternator. Key on engine off there should be near zero volts and when the engine is running and the alternator is charging the voltage should the charging system voltage (13.8 - 14.2 volts). Voltage drop the alternator case to battery negative. Voltage drop the battery positive circuit to the Black/Red wire (Large wire on output post) and the Yellow/Black wire in the 2-pin connector (sensing voltage). Looking for 0.05 volts maximum.

2. Disconnect the 2-pin connector at the alternator when the engine is running and the alternator light is on. The light should go out. If not, then there is a circuit problem (shorted to ground).

Suggest replacing all the belts also. 1st belt, remove coolant reservoir. Loosen the pulley next to the res. then there is a tension bolt behind it. get under the car, the alternator is right there on the passenger side. possible under a small shield. Loosen all the bolts on the alternator, then there is a tentioner on the alternator. Loosen that, remove belt, then take out the rest of the bolts, along with the plug and the ground wire to the alternator. for the P/S belt, loosen the other pulley 14mm, and then the tention bolt is another 12mm.

I puled off my old alternator and forgot to put

So, you have an integral regulator on your alternator.... so you have to connect the output of the regulator to your battery. You also have to connect between the regulator and the alternator. Hmmmmm how to describe....
using your descriptions of wires and prongs.....
Connect Wire Color to Prong

Yellow (w/wht dot) A+
White (w/blk tracer) STA
Black (w/orange tracer) Bat (alt output)
Ground wire Grd
Orange (w/Lt.Blue) F (field)
If battery was connected, the Black with orange tracer wire would have +12 Volts on it at all times

Vehicle: '97 Nissan PU, alternator

ok we have four connections at the alternator( black wire is ground) (white with blue positive direct from the battery)
and two wires connector in the regulator(yellow with black that goes to charge indicator the red light and goes to fuse 7 10a fuse block inside) the blue with yellow goes to fuse 65- 7.5a in the left fron engine comparment fuse box))#1 check for ground at the black wire= #2 check for positive at the white with blue wire (allwas with power) this wire is protected with 100a fuse is in the left front engine comparment fuse box,
remenber== check the 100a fuse
and the two fuses that protect the regulator.
when you turn the ignition switch to the on position power goes to the alternator by the yellow black wire and activate
the alternator to work.
