electronic distributor wiring

bluesteel · Post by **bluesteel** » Fri Dec 16, 2005 8:42 pm

can anyone tell me how to wire in the electronic distributor in the ea81

the old points one just had the one wire coming off to tell the coil when to fire

but the new one has 2 wires coming off and im not too sure what to do with them

any help would be great
cheers
Johnny

I belive each go to either side of the coil but i can't remember which ones. Sorry. Maybe someone with an ea81 wiring diagram can help. The wires are yellow and black/white i think.

Yep you're on the money there Subarino!

Black/White goes to Negative of the coil, Yellow goes to positive.

I'm gonna say blk/wht to +(pos) battery supply via ignition switch.
Yellow is the "points" wire, ie to -(neg) terminal on coil
maybe we need a Poll on this one ? 8O
can check in da morning......ah sh.. it is morning,nah too early to be popping the bonnet.....

Hey Yo

I'd also like to know the set-up as that be my next/first mod after the Christmas run down south. If anyone Perth side has a spare or knows of one around I'd surely be interested.

Thanks
Kaffine

Shit i think fred-sub might be right. But everyone wait for conformation before trying it.

Nah, I went and checked under my bonnet. Unless it's possible to reverse wire a coil, I'm not sure about polarity switching with coils.

Hmmm, that makes me think of something else. I installed a tacho, and the only way it would work was to wire it to the positive terminal when the manual said negative terminal. Makes me think even more that the coil is wired back-the-front.

xaymaca... DUDE!!!! thats scary... Tacho should definately be Neg side of coil. *shivers*

I think u may have done something i didn't think was possible.

cheers people...

ill wait for someone to check in da morning... well later in the morning

and wouldnt you know it... had to go help a mate jump start his car tonight... but the soob wasnt going 8O and i had parked the twagon in so i couldnt go in that either 8O

so i had to take the ute instead, but i took bluesteels battery with me so there was at least some part of a soob to the rescue

oh and xaymaca... at least now i know it wont fry if i wire it up wrong

*runs and hides*

Bags wasn't me!! Was like it when I got the car!

Blame the communists...

On that note... If my coil is in fact wired incorrectly, how exactly is my car running?

Would that contribute to note being able to run as much timing advance as others... ie sometimes pings on 10degrees

I would seriously drive that to an auto electrics to get it checked out.

Haha, I might just do that... Maybe that can be tomorrow's project! What a mongrel

My old MY had black and yellow wires going straight to the coil as well.

fredsub · Post by **fredsub** » Sat Dec 17, 2005 10:55 am

I have to blatently say I'm Correct

Yellow is points to (-) coil and Blk/Wht is to (+) coil and battery supply.

The secondary is grounded via a gap to the (-) side I think, so if you hook up
+the wrong way, it will work, but the voltage spikes on the (+) side would be crazy I expect.....and start affecting other things.......

cheers guys.. either side of the coil worked a treat...

yellow to the side of the coil that had a yellow wire and the black/white on to the side with a black wiire

fired up and is all good

just gotta find a timing light and set the timing

thanks heaps

John, the wires go to the coil, yellow to the neg, black/white to the pos.

I multimetered my coil today and I was getting a nice 13.8V to the negative of the coil... How healthy.

I spoke to an autoelectrician about the effects and he said with the earlier type of coils I will just get a weaker spark. Hopefully I will be able to get a bit more goodness after switching it over!
