hi all
i have some questions.

im wirring my hei mod(again)
now i solder the connections for good

but i have no spark i dont know why

can you help me check the wires?
this is how i wired


redrawn the wire diagram


Orange Ignition pulse ----> W


the Hei Earth ---> G--->hei mountin point.


Yellow blue.tach signal ---->1k---> (go to coil - red)


red coil- --->coil ---> C


the disty


coil and hei



but where are these from




connect them?


made the new hei wires
Hei Coil + and Coil - Connection to Hei


Coil+ and Coil- +tacho connection(inside fuse box 1k ohm)

the connection to original harnas( tacho coil + and coil-

Hard to tell just from your pics. What side of the coil is + and what's - ? I suggest you retrace every wire checking continuity as well. What year is your car?

my mx is from 1992
i install my wires new harnas tomorrow
but where are these from?

B+ red --->B on hei B-blue--->C on hei

It looks like you only ground the W and hole near C through the hole at C.

I grounded it extra from W

Nederlands.
Volgens mij moet je de draad tussen W en C ook nog een keer extra aarden, niet alleen het gat van C, maar een afsplitsing bij W naar het chassis.

i make the extra grounding point.


connected the coil wires and tacho from orginal harnas to mine
yellow--->tacho
red--->coil -
bleu--->coil +

to be melted


coil+ --->B
coil- --->C


when i crank i get still no spark from the coil
coil resistance is good coil lead wire to.

i get a pulse signal to the Hei--->g
but when i set my car in second contact
i get voltage at both coil terminals

coil+


coil -

If this wasn't such a PITA for you it would be funny. That's your VAF plug and without it plugged in you ain"t startin nothing. So plug it into your vaf and hey,,,,have a nice day.

lol
i know that the vaf plug needs to be connected
i took my intake out to take decent pics

and its not the plug its the wires beside.

when i crank my car coil+ stays at 12 v.

but coil - goes out with a testlight and wont light back up again.

no pulse from hei?

Check the wire colour code in our on line manuals. http://www.mx-3.com/manuals/index.php

i was and looking for it in the manual but i cant find it

when i start the car i get no pulse signal to my coil
i get 12v on coil+ and coil - thats ok,but while i am crancking coil - should give ground pulses.
but i dont get them.

i have pulse to the hei
have earth
have power on the coil

is my hei broken already?

greetings kevin

i made a new earth wire i spitted id and now i got a spark from my coil. yeah!!!
but i have no spark on my spark plugs


sanded the contact points and rotor
is the disty broken?

i routed the wire back and it whas a earth wire they ar all going to 1 kable in the harnas.
but still no start

have spark from my coil but not on my plugs
