whats the difference between the 3G, and the PowerMaster 140amp alternator, I have the PowerMaster 140amp with one wire hook up, like a 20 min install, should I be running a fuse in between the alternator and the battery, doesn't say in the instructions
The Green/Red Wire is what I need to tap into in order to use the FFI/RJM Harness correct?
Awesome, Thanks for the Help, no extra fuses for me correct? This is my Winter Project this year, I already snagged a NOS Motorcraft 3G and I have my Power Wire and Fuse, and the FFI/RJM Harness is on the way!
would there be on a fuse on the back of the powermaster alternator, because the charge cable that it comes with doesn't have one, or is it something i could go pick up, Post has me thinking, I recently melted the charge wire to the fuel line right below my pressure gauge, I cut it and reconnected and was going to run the charge wire through some wire loom to the battery
This is almost the same thing as a 3g correct? will i still need the new wiring?
sorry to bring up an old thread but I have a question.
I recently did the 3g conversion on my 88 and I followed the diagrams in this thread where you just simply splice or tap into the smaller of the three wires in the rectifier harness and attach it to the stator port and your done.
I haven't tested this yet because the car's down for a transmission swap that's taking way too long because of other little problems popping up as we go so what else is new.. anyways my reason for this post is because I was reading my August 08 issue of MM&FF and checked out there article in titled "dimmer switch" page 152 where they install a 3g alt, mini starter and efan. In this install they cut the rectifier wiring harness off completely and attach the stater wire to the 3g but also connect the two remaining orange/black wires from the rectifier harness to the power lug of the 3g alt.
So my question is why did they attach the two orange/black wires to the alt's power lug and is it needed? Should I concider doing this as well or stick with what's been discussed in this thread already?
Many of the ubiquitious instructions have folks reuse those stock wires. My feeling is that it's either a lack of knowledge about the issues the original wiring had or it's to allow a wider array of alternator outputs to be covered by 4 AWG cable. Otherwise, 2 AWG or numerically smaller cable would be requisite (4 AWG and the stock wires can carry almost any alternator-rating on paper, but aren't so effective in reality).
Soo could I pull the two thicker wires (orange/black) wires from the wiring harness and unhook them from the starter solenoid and be gone with them? Or do I need to keep them attach to the starter solenoid and hanging behind the starter for some reason? Also if there attached and hanging aren't the concidered HOT and kind of dangerous?
OK, so let me throw this out there then.......should you just add the additional 4ga wire on top of the orange/black that go to the solenoid? Perhaps I've missed something here. I'm so setting my car on fire.
