308 vk commodore

[lindsay1]

hi guys...
just want to know what is the easiest way to start my 308(red) engine without using the loom as not being put on the road...as this is what we have done

got a vk comm with a black 6 not injected...put a rebuilt 308 and turbo 700 trans in it...all nicely fitted...

my problem is i am not getting spark and dont know which wires to use from the old loom (6 cyl loom)...any help would be good....cheers

[Jonno]

to start the 308 u just need a fat lead from 12v (+battery) to the starter motor...and a earth lead from the starter motor to earth
and hen pretty much the same for a altinator

i think

oh edit: and wire it to a ignition so u can stop and start it

with the 202 and not gettting spark is the firing order correct

[mr j-man]

may be a dumb ? but do u have any spark when u remove a lead from the plug??

[lindsay1]

no there is no spark at the plugs or points...putting new condenser on it tomorrow...really want to know what wires to use from the 6 cly loom

[mr j-man]

if your not gettin nething from the plug! start backtracking to your dizzy rotor, then the coil and so forth you may have lost somethin along the way...is everything going to ground?

[RVK 355]

ther should be a big pink wire in the VK engine loom, that goes to the posotive side of the coil

[lindsay1]

ok but how many wires come from the dizzy and where do they go???

without chasing your tail too much just grab a gregorys wkshop manual..they have all the wiring schematics and are colour coded too and are pretty straight foward to read if u have abit of nouse! the 6cyl main wiring harness comin from your ignition shouldnt be 2 diffrent...from memory mine had 4 wires in total on my vh..which is an 8. the 4 biggest wires are the main ones to get it runnin all the other lil ones are for your temps,oil. ok from ignition barrel is red to a main fuse, to your +batt then to your starter, from your starter to a normally open circuit relay which closes circuit to supply power to your ignition setup! once it gets to there its all 2wires maybe a 3rd which are red&blk or brwn/black...black always negative. without seeing it its hard to sus it out...but u should lable the termination point of each wire so u couldve referred back to it to rewire! but yeah go the wkshop manual..its a no brainer

should be 2from the diz..1 definately goes to the coil not too sure about the other..it may do too! ........shit i only removed the harness and ditched it from my 308 2wks ago. i knew i shouldve took note as to what went where!

try this it may help for labeling as what is what...i know it says hz
but it is all the same

[mr j-man]

a multimeter helps to define which is + & -

[lindsay1]

this is what is happening...can turn engine over by hitting starter but there is no spark....when we try with the key you just hear a click in the relay box...i have heard of a 3 wire setup so would that work and it is a carby engine not injected...

[lindsay1]

the spark is not coming from the 308...the 202 is long gone now

[mr j-man]

gota multi meter?
does it run nonstop when u hit the starter? or does it just crank over?
theres 3 terminals at the starter...there is a nut type(red from battery) terminal and 2 spade connection terminals...on the harness find two spade connections (they should be paired 2gether)- maybe a black and purple! black is (-).

[lindsay1]

just cranks over...not throwing a spark thats why putting new condenser on it and need to know where 2 wires from dizzy go to...

[lindsay1]

also wont turn with the key just a clicking sound in the relay box

condenser??? the 2 from the diz go to coil! there should be 3 connections on the coil! 2 of which are for the diz and one is from the supply power. mine from the diz has one spade connection and 1 ring type..the ring type goes to the connection at the coil which stands alone. and there should be 2 connections side by side or bridged together in some way!...sorry man i dont think im helping really...if i was there lookin at it ...it would be runnin

[lindsay1]

the condenser goes inside the coil...as for the 2 wires from the dizzy is one pos and one neg and is it the big pink wire that goes to the pos on the coil...

[ari666]

hehe. what a random thread.

to start with, OP, you said there is no spark at the points?? so is it a points dizzy? if so there is only one white wire (i think) which goes to negative on the coil [need to confirm that] if its points, you will need to make sure the balast resistor is working properley too.

if you got a HEI dizzy, two wires (as mentioned) black and red, obviously black - and red +. but somtimes itll be green and purple and i believe green is - and purple is +

from the loom that comes out of the drivers side of the firewall, you will need just two. a fat pink and a brown, the fat pink is ignition 'on' AND 'start' and the brown is tacho. now the tricky bit with the pink is that if you have a dud tachometric relay or blown fuse, that pink wire will only get power on ignition 'on' and itll switch off in the 'start' position, which means you will crank and crank and nothing will happen, but when you check it with the ignition 'on' itll show as having power. that stupid wire got me once too really badly. took 2 days to figure wtf i had done. so go check that first. stick a test light on it, then turn the car to 'start' and if the light goes out, theres your problem.

[the_boozer]

as its a points distributor and you only want to start it wire from positive on the battery to positive on the coil with the 1 wire from the distributor to the negative on the coil and screwdriver the starter.
this will do for a short time, with out the resistor the points will turn blue pretty quick. you may need to power up a solenoid on the carby to get it to ideal cant remember how quaddies go haven't touched a v8 for a while.

[lindsay1]

i put a new balister on the dizzy and yes it is points...when we crank with starter motor we now get spark...but what i face now is i cant crank it with the key and the elec fuel pump is not turning on...do you know what wire and what colour it is for power to pump and any ideas on the starting with key...thanks...

[ari666]

what kind of elec pump is it? power is usually a 7.5A fuse in the rail, but if its an elect pump off a EFI 6 then there will be WAYYYYYYYYYYY too much pressure for a quaddy.

[lindsay1]

the motor that came out was a black 6 not injected and the guy who took it out pulled the wires...in the fusebox under the bonnet it says for the pump its number 4 but when you look in there there is nothing in there to hold the fuse in....and i know the pump worked when the other motor came out....also any idea on why its not cranking with the key...does it need 2 blade connecters for the starter...

[ari666]

the pump will need to be hooked to the tachometric relay. best idea is to hook up the mechanical pump that came off the engine you have, if its a points engine, then itll have a mechanical pump.

problem solved.

[lindsay1]

it does have a mech pump on it...but i still need to know why it wont crank with the key...dont want to keep trying to start it with a screwdriver...

Have u got it in "P" for park? Or neutral, does the neutral safety switch work? Is the power getting to the ignition, is there power coming out of the ignition (purple wire I think), have u tried the starter solenoid wire on the different terminals on the solenoid?

Put a test light on the starter wire going to ur solenoid, get someone to turn the key and see if there's power getting there. If there is, tap the solenoid with a hammer incase it's stuck and try again, if still no go maybe it's rooted?

If there ISN'T power at the solenoid just work ur way back. Try the input and output of the neutral safety switch, if power goes in but not out, then ur switch is dodgy, either replace it or cut the wires and join them lol. If there's not power at the switch at all, check the ignition.
