alt wiring

[monterey1962]

The two black wires that were on the original plug (which I snipped off) go onto the alt's post that has the 8ga. wire to the battery. That's all that is connected there. I don't know which wire is specifically for the warning light.

thats exactly the pic I cant make out.... the 3 light colored wires from the plug connector and the white stator wire dissapear into the wire loom.
The one black wire you can see coming off the main post dissapears under the wire loom.

it doesnt help at all!!!!!!!

specifically, which wire from the 3G gets connected to the battery warning light?

[monterey1962]

In this pic you can see which wires go where on the back of the 3G alt. I ran an extra 8ga. wire to an 80amp fuse, then to the battery's positive terminal.

Yes, "amp" light is functional.

[85crownHPP]

how excaclty did you wire it??? and is your battery dummy light functional?

[monterey1962]

The 3G was $220.28 minus exchange of $75.71, so it was $144.57 when all said and done.

Monterey, if you dont mind me asking how much did the 3ag cost from car quest?

If you're at idle with everything on and its above 12 you're fine. Mine unloaded runs a bit over 14, and somewhere in thr 12.5-13 range with a bunch of crap turned on. You also have to consider your voltmeter is sampling voltage from somewhere in the fusebox (probably), so there is also some voltage drop across the wiring from the battery to the fuse box. If you check it direct at the battery, it will be slightly higher.

How much drain should I expect with the fan blower on? It pulls the voltmeter down to 13 from about 14 when on high. The needle goes lower with the brakes and signal lights on after that. Otherwise, the new alt handles everything else alright with the fan off. Just seems that the blower fan pulls a lot of power.

Ran to the stereo shop and got 8ga. wire, 80amp fuse, and fuse holder. Had to drop $37 for it all. Ouch.

Just for future reference...buy your wire from a welding supply shop, its much cheaper. 4 gauge is $3/foot at stereo shops versus $1/foot at Princess Auto here.

i do mine with the bottom bolt out then line it up and install the bottom bolt with the belt already installed

That's exactly how I did mine. Belt didn't need too much snugging up, either.

yea it's a bit tricky to get the altenator belt on.......i do mine with the bottom bolt out then line it up and install the bottom bolt with the belt already installed......i forgot about that.........may be able to use a 505k6 belt.......depends on how much adjustment you have

[Lincolnmania]

very good! nice work mang!

[monterey1962]

3G alt is in and holding charge like it should when under load. The only real problem was getting the belt on the pulley. The bracket doesn't allow the alt to swing back like the stock alt.

Thanks for the info, man. I'll hook directly to the battery since I just put a new terminal on there. All the wiring looks good. Nothing is melted.

Stereo shops will have those fuses. Mine uses 8 guage wire I think. You can connect it either direct to the battery, or to the starter relay with the 583258 other wires if there is enough room. All the fat wires connect to the same terminal on the back of the alternator. Also, pull the split loom off the alternator wiring harness and make sure those wires aren't all melted together. If they are, just unplug that whole section of the harness at the connector on the fender and connect the white wire from the regulator plug directly to the terminal on the back of the alternator. Also, up the fuse to a 125 or 150 if you do that.
