MK1 golf gti converstion help (no spark)

right it seem i have no spark coming from my coil

both black wires are on the + and and the red and green are on the -

there seem to be no negative from the coil when using a power probe when the ignition is off

the TCI unit is earthed to the battery too

any ideas??

also if anyone has GTI wiring diagram on the net could i have them please

thanks jack

immobilizer fitted ? Going faulty ?

ive tryed about 3 ignition moduals mate after reading that still no luck

and nope no imboliser

youll only get an earth to the coil when the engines turned over as this is what creates the pulsed spark

terminal 15 should see an ignition live

terminal 1 should have the green wire from the tci unit going to it, and the red and black wire on the original car loom going to it tofeed the rev counter and fuel pump

you say you have both black wires to the coil… you should have a black wire from the original loom which is a 12v supply going to it, and on top of that another black wire, and another black and white wire… the latter both feed the ecu and tci

should help

im not running a KR 16V
its a gti 1.6 engine so there no ECU

ah my bad sorry… it was the 'conversion' in the title i think that convinced me it was…
either way principle is the same. 12v supply to terminal 15 on the coil, and trigger wire supplying an earth to the coil as the engine spins

its all wired up correctly it jusst seem theres no spark comign from the coil
im begining to believe my hall sender fecked

You can test the hall sender, there's a little section for it in the haynes manual. Basically you're looking for a lowish voltage "pulse" in the middle terminal.

how do i test this?

seen as my gti manuel got robbed by some cunt other week

with the plug out?
whats the voltage?

can you copy this out the manuel or something please mate?

cheers jack
