hey guys i was just wondering why i wouldn't have spark from my coil i have checked the fuse and i have also tried a different coil still but won't spark
any help would be appreciated

[89_tintop]

Do you have power to the coil?

Is it "switching" on the negaitive side??

Were you doing anything when it happened? Driving... Playing with wiring... Installing something

Could be, a dizzy failure. Do you have a multimeter, check the ohms of a working dizzy, and yours.

Its after sundown, I cannot check mine, sorry.

Well I can, but, its dark, an im unable do check.

[stewy91]

i was just about to go to work i got down my driveway and cause i was still half asleep i stalled it then it just wouldn't start back up and it doesn't seem to have power at all like with the reds on i can put a test light on it and it has no power

[DMAC]

I've had my fair share of this. Here is my order of tests.

Remove dizzy cap. Turn crank use a 17mm spanner on the crank bolt (clockwise)

1. Rotor turns. Yes - timing belt, cam shaft pulley, dizzy drive all good.

2. Check Halls pickup and ignition module.
Take out rotor.
Position the dizzy shaft so the trigger (4 pointed thingy) is away from the halls pickup.
Remove the two wires from the coil that go to the coil.
Place a multi meter across the 2 wires. Use a low voltage setting.
Poke a screw driver (flat blade )infront of the halls pickup and remove quickly. As you do this the multi meter should read some sort of volts.

If no deflection (no volt reading) the ignition module is Kaput!

The coil is more than likely OK since you have tried 2.

Hope this helps.

if you have no power at the coil positive its likely blown the engine or whatever its called fuse

[stewy91]

well i will give that a go tomorrow and if its no good will just get a auto electrician to come have a look i will let you guys know how i go and what was wrong with it if i can get it sorted thanks for the quick replies aswell.

[stewy91]

okay so i had a bit more of a look today it seem to be earthing out i believe the coil will have power sometimes and then its gone. Also when it loses power i seem to lose the sense and battery light power on the alternator aswell

[steak_knife]

Fusible link at the pos battery terminal??

[stewy91]

are you talking about the fusible link from the alternator to the battery like the main cable would that be enough to cause it to short out as i don't have a fusible link in there

[steak_knife]

hard wired?????

have you looked at your main earth for the eng??

Also there are 2 big plug's glove box side of the fire wall, thay run the whole frigging car, you "may" of gotten water in there at some stage, worth checking.

[stewy91]

yes it is hard wired was like that when i got the car. I have also been meaning to get a fusible link but keep forgetting and i have checked them plugs already they are seem to be fine no sign of anything wrong with them. the main earth for the engine is on the the started motor

[steak_knife]

Did it just stop or has it been playing up for a bit, I.E hard to start??

[stewy91]

yes it has been hard to start for a while assumed it was just the carby but i had got that rebuilt and was still kinda hard to start

[steak_knife]

dash light's doing stupid thing's on start??

Do you have a spare ing switch laying round you can try??

[stewy91]

dash lights have never played up before until now. but it seem to only be the battery light that won't work but then it won't light up with the test light either

[steak_knife]

Have you replaced anything, fitted anything lately??

It's not uncommon for the switch to shit, not saying that your problem, but it does power up what you've lost..

[stewy91]

well i have done alternator upgrade and fitted rebuilt carby

you checked this?????

[stewy91]

yes i have checked fuse i even checked behind it and most of the loom it doesn't seem to have any burn marks or anything. and it has power sometimes but cuts out after a min or so

Any part of the harness getting hot????

Did this start after tha alt upgrade??

[stewy91]

none of it getting hot and yes started day after

[steak_knife]

What's the charge rate??

All bolt's on the alt tight??

Just for kick's, disconnect the atl, power & plug & see if it still does it...

[stewy91]

Charge rate is about 14.8 and have already disconnted still didnt work im lost on it I dunno what else to do

[steak_knife]

Your in Deception Bay

I know I've asked about the earth, but how did you check it?

& going by that it run's for a lil while then cut's out??
Does it take a while to start again??

[stewy91]

It doesmt rum just gets power to the coil then cuts out again

[steak_knife]

Got a mate with a trailer??
Bring it over & I'll fix it.

[stewy91]

were abouts do you live

[stewy91]

okay so i have pulled most of the loom apart and i found four burnt out wires now i have followed these wires and they are those little green plugs on the side off the carby both plugs had burnt out.
