Hey Guys,
I'm looking to install a Silicon Chip (Jaycar) HEI into the ute this weekend...
only i've lost the paperwork/instructions !!
I've built it, just need to install it !
Can someone tell me how to set it up ??
thanks,
Cam

Joo is a massif dong cam!
As marked on the PCB
+15V - 12V from Ignition
TACHO - TACHO
+HALL - +HALL (only if using hall effect sensor)
PT1 - To Points 1 (Hall Signal if using)
PT2 - To Points 2 if using
REL - Reluctor +ve if using
GND (below REL) - Reluctor -ve if using
GND (below 2 5W resistors) - Case + Chassis ground
Centre pin of darlington transistor - Coil -ve
To set current limiting
adjust VR1 to read 0.25V across the 0.1R resistor whilst the ignition is on but engine is not started. You will need to short your ballast resistor if you have one.
Once all that is done you should be ready to rock 'n' roll.
If you want more info just tell me what sort of ignition setup you are going to use (Hall effect, points, reluctor etc.)
Also are you using the programmable ignition? If so more wires are required.

Why didn't you just come and steal one of the 6Cyl electronic dizzies I have in the shed???!

cos gaycar is whey cooler  and he does have the programmable ignition to set up later.

Thanks for the Info Toobs!
I was going to put it in on the weekend, but after melting my clutch cable i'll fix that 1st...
The HEI Is probably better than the factory elec. ignition Clint... (I'm not really sure about this  )

gaycar HEI has longer dwell time (all bar 1ms for spark) for 'extra coil charging' = why the Bosch GT40's melt so soon..

Hey Guys,
Having issues with the HEI
Put it in, and tried to adjust the current, but i can only get the voltage across the resistor to about 0.18V ...
I'm using a bosch black not oil filled coil....
Cant remember the number on it, from memory i tried the other coil i'm using GT40, and that didnt work either...
With the voltage set to max it doesnt work !
any ideas ??
I doubt the HEI is going to make much difference as i rarely rev the ute past 4,000rpm....

i found that the voltage dropped off quickly once power was applied to circuit.... (i think.. it was a while ago), so you need to hook up multimeter, then turn on and see what max voltage is... then adjust and test again...
i think 
i will have to do it myself eventually...
GT40 = bad mmkay...
mine melted after 1 or 2 weeks.. the next crappy coil lasted about.... 3-4 years...

i also found midrange and idle was where it made a lot of difference

Are these kits worthwhile getting? what can you do with the programmable ignition kit?
any advantages?

Hey Stu,
I know there is uses with the GT40, silly "sports" coil
With the other coil the voltage got to a certain point and wouldn't adjust past that. But the coil did start to buzz !
Maybe i should just be measuring the current to the coil...
I gave up seeing as it wouldn't start, and pulled the HEI out...
Now the ute moves again !

did you solder in both sets of points components?? i did the first time and it made it "not go".. took them out and it worked...
current will also decrease quickly since the coil saturates in milliseconds..
did allthe other tests work out?? what are you triggering with?

Hey Stu,
cant remember if i did both sets of point components...
And i've lost the info for the kit, so i'm a bit rooted...
I dont think so tho, as i'm only using a single point dizzy.
Other tests ?
thanks,
Cam

strange, when i wired mine for my car, the little plastic washer that was insulating the darlington transistor started to melt so i pulled the HEI out of the car quicksmart.
Haven't put it back in either, i assume i wired it up wrong as well but i removed the old coil completely and whatever wires and boxes were going to that, so maybe that was my issue when i did try to wire it.
but if you want the full instructions, i can scan them for you or photocopy it and post them to you (for reference only)

Hey Barned01...
are you talking about the silcone impregnated washer ? the flat one about the size of the tranny ?
Did you mount it correctly using the plastic bush ?
Other wise a copy of this info would be great if you could scan and email it to me ! cam_zh@yahoo.com
thanks,
Cam

Has anybody had any sucess fitting a hall sensor in place of the points in the Dizzy? The HEI kit can be fitted with the points, but I suspect that this set up will still suffer from points bounce. Anybody?

wow if i had a digi camera it would make life so much easier.
in order i placed it on goes as such:
the metal box, then a little square flat insulator, then the transistor, then a little plastic white washer that goes inside the hole of the transistor, then a metal washer then the bolt through the whole lot.
Iwill scan thenm either tonight or tomorrow if i can grab the scaanner, otherwise are you happy to wait till monday when i can do it easily?

i use mine with points.. i'm not sure where points bounce, but mine does over 8000rpm with no probs that i can see.
since it's only the opening of the points that triggers a spark, as long as the points close before the next spark should be ok.. ie points float is ok, but bouncing and having multiple openings may not be good...
i have a kit now that i am constructing to work with a toyota VR dizzy.. apparently has triggereing problems but we'll see..
if you want to buy me a hall effect sensor from jaycar (they have them back in!!) i will test it

Yeah when the Dizzy gets up a bit of speed the spring on the points cant be as efficient as it doesnt return as quickly. I've been planning on trying the HEI for a while now and I wanted to try adn chuck a hall in as well. But as I always say
"I'm no a gynochologist but i'll take a good look".

Hey Guys,
Thanks to Barned I've now got the info again !
I think i've found my issue !
I've installed both sets of points inputs ! so it never sees the variation in input state !
doh !
I've also installed the 5.6v Zener as per the eratta which may be causing an issue, i'll hvae a fiddle this weekend..
Now i just need a more reliable starter motor !!!

Heya Cam,
heh heh, i did exactly the same thing.. thought, well why not put both in.. and had same issue.. no go...
i can't remember if i have a zener as per errata? when was the errata dated?? should i have one now?

The other thing thats easy to stuff up on is when you install VR1 if you bend the legs too much you can make the pot go past the 270 odd degrees of rotation its supposed to have... if it goes past that point you can very easily f'ck the pot.
Note: The two legs that are on the one side stop the pot from being able to be rotated past 270 odd degrees... bending the two legs removes this limit and f'cks the pot.
Just a thought.

Hey Stu,
The Zener mod is dated the 4/3/02...
It suggests to do it only if your car starts fine but then dies and wont restart, something about q2 not turning off ?
They also suggest with this mod to remove the coil from the engine if thats where it's mounted...
It's kinda funny about the twin points thing, as i cant find anywhere in the atricle about only putting 1 set in if you have a single point dizzy... But i saw this on the SC website....
And after looking at the circuit it makes sense !
i'll try and refit the elec. ignition this weekend, work permitting...
I'm interested to see how the midrange improves...

Hey guys,
Finally put it in the ute last weekend and it worked !!
Could only get 220mV across the 5ohm resistor...
But the tacho doesnt seem to work, i'm using the tacho output, i'll try changing the tacho back onto the negative side of the coil and see if that works....

Cam

Hey Guys,
Got the tacho working today by connecting it to the negative side of the coil..
I thought about hooking up the CRO to look at the out put of the tacho output, but thought, nah..
If any one wants me to i can...
cya,
Cam
ps, i also noticed my timing was way our (retarded) but not sure if this was due to the HEI or it was just set that way ! i'd never put a timing light onto the ute before !
