Re: THe NAC Lots-O-Post Thread aka North America Home Owners Association Thread

and.... Just sold my engine.

lol.

I'd rather not have to run a hokey crankshaft signal converter box and 20 extra wires. Should be able to find a decent engine that would bolt right in now. Maybe even another 6.0 If I'm lucky.

6.2L or 7.0L

Just ordered a 1.5:1 ratio steering quickener. Should put my steering at 2.3 turns lock-to-lock instead of the factory 3.5.

Also $99 is cheaper than the $600+ 2.75 turn box from PSC, that isn't drilled & tapped for hydro.

Should be a fun little project.

What a nice guy!!!

ITS THERE. I SEE IT.

Im going to install an underdrive between my wheel and steering box. if I can't get the hydraulics to work I might as well gain some steering power somehow.

Actually, that was brought up...in the event the pump/box takes a shit, you can just flip the quickener around and make it a slowerer to get some leverage back.

The holes aren't centered but I'll probably make the mount with two sets of holes in case I ever need to do that.

Ok... Back to wiring. I verified I have to correct wire.. I think. 85 off of a relay is ground, that's the wire I have... But it's hot and when I ground it I blow the fuse. How does this shit work?
 
Re: THe NAC Lots-O-Post Thread aka North America Home Owners Association Thread

Like magnets.

I attempted to figure out WTF you're trying to do, but I'm not going back 3 pages of bullshit to figure it out.

So what are you trying to do?
30 is hot
85 is ground
86 is switch
87 is load
if you've got 12V on the 85 leg you've done it wrong, that should only be the ground for the coil that you energize on pin 86.

I think he's trying to make a switched ground.

It's a switched ground relay I believe... I read on the rover forum to just add a ground to pin 85 to trigger the relay.

What if I hit the wire on 87 w 12v? Would that do it? That bypasses all of the fuses and whatever though.

80k mile 6.0 with harness and ecm for $1000

complete wrecked 04 suburban 6.0, 4l80, 4wd and 14 bolt for $1000

140k 5.3 long block for $200

unknown 5.3 from sams pull a part for $300 (i think thats the going rate)


anyone wanna haul a suburban to my house?

could probably make most of my money back on that one.
 
Re: THe NAC Lots-O-Post Thread aka North America Home Owners Association Thread

thank you for the most non informative answer to a direct question ever.

WTF are you trying to turn on in that wiring diagram? The condenser fan relay?

where does k5-4 go?

Where is it? I love an opportunity to going BROing and towing.

Actually, he just offered to deliver it for free. But Spencer Mass.

I'm gonna check it out. if it looks alright I'll go this route. Even parting stuff out for cheap money then scrapping it I should come close to breaking even and have a free engine.
 
Re: THe NAC Lots-O-Post Thread aka North America Home Owners Association Thread

from the diagram it looks like 85 is 12V and 86 is grounded when X113 is closed

85 vs 86 shouldn't matter which is ground or which is "switch", it's just a coil.

Relax, if you're that worked up about answering his question go back and read the informative initial post, no need to be short with someone because you're too lazy to do a little looking around.

$50 buys you a warranty on an engine at sams.

Show up, we jam the battery cables into an 18v cordless power tool battery pack to get odo mileage. Make sure to use an obviously crashed donor, I'm sure there will be one.

Chop exhaust, unbolt tranny, cut rad/PS/tranny hoses, loosen motor mount bolts, wad all the accessory BS and wiring up on top of the engine, unbolt bellhousing, untie some seatbelts through the manifold runners or motor mounts, call the loader operator out and have it dragged out and loaded onto the trailer. $316 with tax, if I'm there, usually. Hell last time I bought a motor they told me to grab a battery off the rack out front and go start the thing up before I started pulling it.

I buy enough shit there with little enough hassle/haggling/BS out of me that they basically let me do whatever the hell I want.

Unless it is a diode-snubbed relay coil (common in some makes), in which case it matters a lot. Been there done that, relay let out the smoke.

Adam, what you want to do is ground the ground side switched coil pin. I can't tell what K5-11 and K5-4 are. Measure the voltage on each pin when the fan is turned on by the ECU, then wire your ground to whichever one is grounded. Warning, depending on how sophisticated the ECU is it may throw a DTC relating to a circuit fault on the relay control circuit if you do this, in which case you need to add two diodes in a wired-AND configuration so each control circuit only sees what it is doing. Any 1N4001 through 1N4007 diode should be fine and they are cheap.

I'm guessing since grounding pin 85 blows the fuse, that is the hot side, in which case you should ground 86, but double check that.

Oh, and there will be 12V on both 85 and 86 when the relay isn't energized, because Ohms Law. The second the relay is energized one or the other will drop to near zero.
