loyale a/c wiring - one wire or three?

Featured Replies

I asked this question a few months back but now I have to ask again...

 

when I got this car the guy said that the a/c worked. The car didn't run so I never had a chance to check. Anyway, when putting the wiring back together after the rebuild, I encountered three wires that appeared to head to the a/c compressor. One was a single wire with a white connector that I could connect to the compressor. The other two wires (green and red IIRC) went to a black connector, but I never found anything to connect it to. Back when I first asked about this I was told there was an electrical box of sorts that mounted to the top of the compressor, and this was where the black connector went, so I've resigned myself to the fact that I have no a/c until I find this box.

 

Last week I went to a junkyard to get some rear discs for my wagon and while I was there I looked under a few hoods. Two of the cars had a compressor like mine with the single wire plugged in, and the black connector not plugged in to anything. Now, I figure either I don't need this mystery box after all, or lots of other people need them and already stripped them off those cars.

 

So, I just had to check again....do I have a/c or not?

 

(FYI, I removed the compressor and never bothered to put it back on since I didn't think it worked, so I'd have to recharge before I could test it.)

Personally I threw all that garbage right where it belongs, in the garbage can :)

 

Now onto your issue. Mine had 2 plugs for sure. This is on the round compressor, not the square one. What kind of compressor do you have? I seem to recall one pluging directly into the pump and another onto a little dongle plug. I can take a closer look at mine and see whats up but if we have two different compressors its a moot point.

 

Peace

I went and took some pics of how mine is set up, but can't log in to the gallery to post them...:cool:

 

Ok.. I have 3 plugs for my AC. \

Plug one-one wire- To AC compressor

Plug two-2 black wires- To AC compressor

Plug three-2 wires(red and green)- To the 'little black box' that bolts to the top of the compressor. It reads compressor RPMs so it knows to disengage if something is stuck. Will not work if this piece is missing/disconnected.

 

However, not all the AC setups had them. It depends on which compressor yours came with.

I have no idea what kind of compressor it is specifically....I'll look tonight and report back.

 

However, I can tell you it's pretty much round (cylindrical). It seems to me the single wire ultimately ran down into the compressor on the top side and very much towards the front, immediately behind the pulley.

it's a "Diesel Kiki" brand compressor...er, I guess (did they really name their company that?!)

 

The Chilton covers some other brands, but I don't see anything about this setup.

 

Anyone else got this brand? Is it one wire or all three?

 

 

**************

Here's some other random info in case it matters....

 

on a big red sticker on the side: SOA329A200, LSM 1-2222

small red sticker: 509640-0633

light blue sticker: DKS-15BH

 

the info on the placard has mostly disappeared, here's what I could see:

Part No. 509630-(erased)

Comp type: DKS-(erased)

Hmmm the only Diesel KiKi I have is from an EJ22 not an EA82. The one from my EA82 was something else. Only one plug was coming off the EA82 compressor. I have 2 plugs that go to the compressor on my harness but only one plugs into the actual compressor unit. I do not remember where the other black plug from the harness goes. I pulled this junk off 4 years ago :(

 

Put in the compressor, hook up the belt, plug it in and find out :) If it enguages when you turn on the AC (you will hear the clutch in teh pulley kick in and your RPMs will drop a bit) then you are good to go. If not we will have to investigate furhter! Don't run the AC pump long at all. The coolant acts as a lubricant also so you dont want to wear out your pump. Get it recharged before using the AC pump once you get it working.

 

Good luck

Will there be a load on the compressor even without any refrigerant in the system?

 

In any case, I'll hook it up and see what happens. Thanks!

 

(80+ degrees today...I better get moving)

It's time to just stick it in and find out :)

here's a question for you...

 

so I have the compressor out and I taped over them end of the a/c hoses so no crap got in them. The car doesn't have a plain ol' "vent" setting...only heat, bi-level, and a/c. Will it hurt anything if I turn on the a/c now? without the coompressor hooked up, I mean.

 

I can't imagine it would,but I've been sticking with bi-level lest I piss off the electronics and mess something else up.

As long as all of the connectors for the compressor are dissconnected, you can use the A/C setting without damage.

 

 

If the system has no refrigerant in it, you shouldn't be able to hurt anything anyway...although I just fried my compressor and it's clutch. There is a leak in the hose, that the previous owner told me about. I recovered any refrigerant I could from the system. The clutch went up in smoke today, as apparently when he re-wired the passenger side radiator fan, it also is feeding voltage back into the compressor clutch, and making it stay on all the time. So now my compressor seized up, since there is no oil in the system, and then the clutch fried.

 

Anybody removing their compressor? I'll take it off your hands...
