Peugeot Wasted-spark Coil Wiring?

[B1ack_Mi16 67]

Well.. today I've certainly fubared my coil.

 

While trying to figure out what pin-outs is what I found this wiring diagram:

http://www.autoelectric.ru/auto/peugeot/60.../xu10j2te-1.gif

 

Anyway I didn't understand that pin4 was supposed to have a capacitator between itself and ground, so I grounded it directly , then turned ignition on and got positive current at pin3. The whole thing smoked like hell and I'm really sure it's gone.

 

Anyway.. what I'm trying to figure out is what pin4 actually does?

Can the coil be used just with pin1,2 and 3?

 

From what I've found out:

pin1 = ECU , switched earth cyl 1 & 4

pin2 = ECU , switched earth cyl 2 & 3

pin3 = Positive (+) feed when ignition on

pin4 = connected to ground via capacitator?

 

On the other hand.. this wiring diagram suggest something else:

(http://www.autoelectric.ru/auto/peugeot/406/rgx/rgx-2.gif)

 

On the last diagram it seem like the pin3 is not used, but pin1 & 2 is still the same, and that it's supposed to have positive feed at pin4?

 

I'm starting to get confused, so if anyone could shed some light on pin3 and 4 that would really be to help.

 

I'm off to the breakers tomorrow to see if I can get hold of a used one, not burning up another new one, that's for sure

Is pin 4 to ground the coil to stop radio interference.

according to the infotec diagrams, pin 1 + 2 are the ecu connections and pin 3 is the 12v+ as you have said. The 306 KFX (tu1.4) wiring has nothing connecting to pin 4 but 106 NFZ (tu 1.6) has pin 4 connected to a condensor/suppresor so maybe it earths itself to the body and pin 4 can be used for suppresion

Yes.. I've done some more investegation now..

 

And it seem to me that the +12v may be either pin3 or pin4.

 

I grabbed a coil-connector plug on the breakers from an Xantia.

It has the pin1 and 2 to ECU, pin3 to condensor and pin 4 is switched +12v.

 

On a Citroen XM I found at the breakers it seemed to be pin3 that fed it witk +12v, and pin4 was just a piece of wire that didn't connect to anything..

 

Probably the condensor ain't necessary and it seem like you can use both pin3 and/or 4 to switched +12v.

was the coil pack on the xantia a 5970 70 one? I was under the impression that pin 3 is the +12v and pin 4 is the condensor. I'll look at other diagrams with the same coil-pack and find out if pin 4 can also be used for 12v+. Was the xantia engine a xu10j2/306 xsi one?

It's definately the 597070 coil, the one in the XM was exactly the same too, but just wired different on pin3/4.

I'm pretty sure pin3/4 is the same thing in some strange way

 

The xantia was a XU7J2?? 1.8 8v engine..

[ablister 31]

yes, you are right. Got 3 more diagrams from infotec. 406 XU5JP (BFZ) has the same coilpack and has pins 1 +2 going to ecu and pin 4 is 12v+, pin 3 does not get used. 405 XU7JP (LFZ) 1.8 8v (which i assume is the same as the xantia) has the same for pins 1+2 but pin 3 is 12v+ and pin 4 is grounded via a supressor. Seems bizarre that the same coilpack is wired up in different ways

If you put a volt meter across pin 3&4 you will find that it's a dead short, so it don't matter if you use pin 3 or 4 for 12v feed.

I agree, the condenser is connected from +12V down to ground to suppress the ignition noise. So would assume that the pins are common inside the coil pack.

What ignition cables will you be running with this coil?

[B1ack_Mi16 67]

Corsa B 16v plug-cables fits perfect if you use the 8v thermostathousing to mount the coil on.

Aha, do you mean the housing for the temperature sender and idle valve?

Yes

Got this from eBay, hopefully it is 5970 70

Looks like the correcy one.

Hi only just seen this thread

 

Ive been using one of these coils with a emerald for nearly 2 years now. Only 3 wires needed to make it work, 12v+ to power the coil, then 2 ign amp switch's. The coil earths through body with the bolts that hold it in place.

 

Issue with the coil is that it will still work even if wired incorrectly and will cause a random pre-ignition in the inlet manifold. I can take a pic of the wiring tomorrow if its any use?

 

And yeah, 16v corsa ht leads will fit fine on a mi16 or gti-s. You have to mount the coil on the side of the head as there not long enough to attach anywhere else.

My coil comes from a Xsara 1.6 but has the same connector and ignition coil connections as a 5970 70. Even the connector from a 2.0 16V XU10J4R wasted coil pack cassette fits the coil with the same capaitor layout (pin 4).

No problem, it probably works with only 3 connectors. Although I'll use it with 4 now.
