Re: 3G advice

Just a note on the LRC F5RU-10316-BA regulators in Motorcraft boxes. Spark Surplus on E-Bay has 5 of them for sale if anyone is interested.

I was speaking to John and saying he ought to be able to assemble a harness for much less than Painless.

He told me he uses O'Reilly, and though I don't have one near me here in CT, I did manage to pick out part numbers for him.

I do not know how much this adds up to, because O'Reilly requires a location for pricing.
I also made the assumption that cables would be the same length I needed for my 460 with the HMEG mounted on the fender liner.

Anyway, O'Reilly #'s

Fuse MEG175 BP

Holder 298900

12" cable SK8412SS

30" cable SK8430SS

Regulator pigtails. HP-3910, S-545 or S-2377

Stator plugs. 645-912 or WPT-1129

Beyond this you need a ring terminal for the yellow/white 'sense' wire to attach at the output lug, and solder-shrink to connect the bk/wh stator plug to the same color wire from the regulator plug.
And connect the existing lt grn/red key on power to the same color wire of the regulator plug.

I don't know how useful this is, but I hope it can help someone

Jim, just to let you know, the Orielly's parts are wayyyyy too expensive. The stator Plug (#645-912) alone was $47.99. Yeah, I know......maybe a listing error, crazy! I went through Amazon for the parts. Thank you!

For me the fuse is $4, the holder is $8.50 and the cables are $8 & $14 respectively.

So, about $50 all in at retail.

$58.31 plus tax to be exact. Most expensive was the 4 gauge wire kit at $30.19.

Oh, those are your prices at Amazon?

I was just adding the eBay pigtail kit to retail Advance prices for the two cables, fuse and HMEG.

$58 is pretty good with that 4 AWG cable kit!
And you'll have the black left over for grounds.

DIY wind and solar storage solutions have really opened up the possibilities with these cable kits.

Gary,
I can share the Amazon shopping list with you too, if you like.
I gave John the option of a 4', 4 AWG cable kit, or the 12" & 30" cables already made up.

Good for you, Tyler! Keep us posted on this if you will. Say, will your new alternator be on a single V belt pulley?

Just saw this....no I have a double v belt pulley. My install is complete with exception of the yellow and green wires coming from the alternator. I logged on to figure out the "fat yellow wire" and the "don't melt your dash harness and start a fire with the ammeter" stuff.

Trying to sort it out without asking questions. Seems like I should be smart enough to look at the Documentation page and this thread and be done already but.... I'm not done yet.

I almost cut out the OEM plug on the truck harness side, not the alternator side.

So, what's the question, Ty?

Re: 3G advice

Alright. Up and running on 3G. I received clarity from Gary and figured out where my hang up was. It was in my brain...

I ended up merging the big fat yellow wire with the yel/white from the alternator and connecting to the alternator side of the mega fuse block. This is the same place the alternator power outlet cable is connected.

The two wires that go to the ammeter were cut (on the alternator side of the plug connector) and zip tied up, connected to nothing.

The rest is out of the Painless and 3G directions.

I found that my fuseable link wire was fried, so not sure how everything was working correctly before but glad to have found and eliminated a future problem.

I also had to use longer v-belts since I bought the large case alternator. The belts come close to the top mounting bolt head but there is no contact. I did not use a shim behind the v-belt pulley and it does not contact the case. I did not tap the tension bolt out to the old size. I used a bolt that fit instead. Hope it doesn't slip.

Yippee! Glad it is working. You are going to love having strong output at idle.

Do the belts squeal on startup? Or, did you get the LRC regulator?

Re: 3G advice

I bought the 0028 model referenced in the Documentation page. No squeal on startup. The test sheet from the box didn't mention a delay though.
