coilpack help needed

bens_cab · Post by **bens_cab** » Sun Jul 30, 2006 7:54 am

hi guys ive biined the cop setup as i think it was my problem so heres what i have

i got a wasted spark coilpack from a peugeot 306 it has 4 wires

1 white
2 blue
3 green
4 earth

how do i fins the 12v

my mate has the same coilpack on his car but has different coloured wires to me he has this but were not sure what they do

1 yellow possible signal
2 red possible 12v
3 yellow possible signal
4 black earth with connector for bolting to head

so do i go with his wiring hes using emerald on his 20vt

also would i need to adjust anything in mt or the ms for this pack im using 2xvb921s does it need them?

Is the coil pack wired so all three coils at one end are tied together? Is that point hardwired to a earth ground mount point? If not just wire the common terminal to +12V, the other ends of the coils to your VB's.

sorry its a 4 cylinder 1 coilpack with 4 wires and 4 plug leads think there known as a dispack

pin 4 has a radio suppresor which is bolted to the head its just 1,2,3 that im not overly sure about

dont want to get the 12v in the wrong place a fudge the coilpack

The pic below is from a random 306 wiring diagram on the web and it may not be for your model year. It would indicate that pin 3 is the common +12v power, pin 1 to Coil1 for plugs 1/4 and pin 2 to Coil2 for plugs 2/3. This would also support the assumption that pin 4 comes from the common power feed to the external noise suppression capacitor. Verify your info.

A way to crosscheck would be to compare resistance readings between pins. Using the picture in this case:

3/4 almost zero resistance
3/1 low resist
3/2 low resist
1/2 higher resistance about double 3/1 or 3/2

Hope that helps,
David

ok the last post was about the resistance just done this test and found this

if i hold the com probe onto pin4 then test i get this

pin 1 to 4 =1.7
pin 2 to 4 =1.7
pin 3 to 4 =1.2

so if ive read this right pin 3 is 12v and 1&2 are signal ?

or this testing all the pins together

pin 2&3 =1.8
pin 3&4 =1.2
pin 1&2 = 2.3

right wired it up cranked it over to see if there was a spark nothing while cranking when i let of the key i got a spark that sizzled for a second then went of

checked my setting had msns dizzy mode of put that back on now the fuel pump pulses every second or so and wont stop with just ignition on no spark?

didnt have this prolem until i wired in the new coilpack
