i am trying to get my 16v running right in this cold cold weather. i have read the guide on how to set it up to prevent it from stalling. i have check near my coil and i dont seem to have the "Red Lead". i have a U shaped jack plug which connects to the coil.
does the Red lead give the ISV power?? i do have the isv control box which connects to the fuse box.

i am trying to get my 16v running right
Hi
What is wrong with it ?
the car takes about 5 to 10 mins to warm up. cant just jump in and drive.. i have to hold the revs above 1000 so else it will stall.

ive read this guide, i just cant find the red connector he talks about. i dont seem to have one.

the red connector in fig 1

Hi
Can you see the terminal numbers on the coil ? They are 1 40 15.
The U-shaped connector to terminal 1, what color wires are on it ?
-
i think from memory, its a red/black and a green wire. i will try have a look at the coil tomorrow.
-
Hi
Well done.
The green is for the tci-h unit.
The red/black is for the rev counter.
If you only have 1 red/black to terminal 1, then the previous owner has bypassed the isv control unit.
-
NOOOOO!!!
what do i do to get the isv running then?? i am getting power to the control box does it mean i am getting power to the isv itself??
oh and what is tci-h unit??
thanks
-
the isv control unit gets power from the fusebox, does the isv buzz? was this a factory 16v or an engien conversion?
-
the car was converted by the pevious owner, the wiring was a a right bodge job :angry:
when i turn the key i hear a bussing noise but i have a feeling that its the fuel pump priming maybe?? when i put 12v to the isv it does click
whats the part number for the ISV?? there seem to be new ones for sale on the bay, i have brought a used one but that seems to be f**ked to

this seller says to give the part number on the ISV so they can send out the correct one for the car.
-
isv needs a pulsed signal, putting 12v to it wont get you anywhere. by the sounds of it the isv wiring is missing due to it not having a proper 16v wiring loom, does it at least have the wur and 5th injector wiring on it?
the red/black wire to the spade connector needs to go behind the fusebox to a white plug for the isv control unit, there should be another 2 pin white plug for the isv wires
-
yeah there is wiring for the wur and 5th injector. i have the brown jack plug for the thermoswitch and for the switch on the throttle body. my car has the hazard on the dash
-
D
26- red/blk- ignition coil pin 1 & idle control unit pin 1 (K-Jet f/inj), overrun cut-off valve (K-Jet f/inj)
is this the wire i should have at the fuse box end?
-
you could splice to that wire yes, this wire is the rev counter feed. the isv unit is just spliced into this wire. the reason its on a spade plug is you have to disconnect it when you set up the base isle

just took the above pics. the first one is what is plugged in to the coil.
the second is how ive plugged in the control box, into the loom
and the third is a plug that is not plugged in when i took the pics, is it needed or is it for optional equipment?
-
there we go, i can see 2 red/black wires from the coil. unwrap that black tape and you'll see the ends of the wires which should go into the white plugs you see in the 16v tuning link above. on other mk2s you just have a single red/black wire.
follow that last wire back to where it comes from, hopefully that'll give you a clue if its needed or not. find the iscv control unit, and look for a single black wire. trace that back and make sure its hooked up to a coil live feed
-
ok i unwrapped the tape around the wires at the coil end.
(http://i573.photobucket.com/albums/ss173/jameock/IMAG0377-1.jpg)
the ends have been soldered together.
i followed the wires back and they both go into the grey trunking. i dont want to cut open that.
(http://i573.photobucket.com/albums/ss173/jameock/IMAG0378-1.jpg)
what do i do now?
should both of the wires go into the isv plugs??
(http://i573.photobucket.com/albums/ss173/jameock/IMAG0362.jpg)
-
1 wire goes to the isv, the other runs the rev counter :)
-
so can i just connect one of the wires to the actual isv valve?? or do i have to conect it to the isv conntrol box loom.
im soooooooo confused!!!!!!! :undecided:
-
sorry i meant one runs to the isv control unit, you can see the other end of it at the white connector. basically you have 2 seperate red/black wires from the bay to the inside of the car. 1 runs from the fusebozx for the rev counter, the other runs from thwe isv control unit. both of these go to the coil -ve, rev counter feed goes direct, isv goes via a 1 pin plug so you can disconnect it in order to set the idle.
what you need to do is find the engien bay end of the isv red/black wire and put a plug on it
-
thanks RJ!! i makes sense now. i will be trying to trace it back to the white isv plug. i think i can see the top of it in the pic.
this should then finally give the value power
