i'm an idiot on this stuff. how do i wire in the 84 dizzy and igniters? is there any shaft alignments that i need to do when putting in the dizzy. i have it all sitting here but i'm not sure how to do it without blowing anything up and/or not starting.

 

check your pm im sending a you a address to goto

 

post it so we all can use it ...

 

dam imagestation wont let me post a link... if you want to host it ill send you a link

 

sure i'll host, although step me trhu as i've never hosted anything before.

 

Very very simple

Trash the stock dizzy, the points etc, and coils, along with ballast crap

Install the coils, install the dizzy, run wires from the trailing ignitor to the trailing coil observing polarity, theres a (+) and a (-) on the igniters (+) goes to 12V ign

Repeat same for the leading coil

Done, enjoy no mucking around with points

 

ok, there are 2 relays that the 79 has that the 81-84 don't have. can i bridge these or do i need to keep them? i don't want to bypass them and fry something, but the haynes doesn't show them for anything else. i know how to bypass these and wire it up 84 spec. just don't want to fry anything.

 

if somebody will pm a email address ill send them the info and they can host the pic. its very eazy but not eacatly like mike said

 

I still have the general concept in my head, I did it years and years ago So I might have missed something, but a quick look at the wiring of a 81 up will reveal the secret

 

ok, did the switch per the mazdatrix doodle picture. i have no tach reading and my car lopes like its cammed. i thought maybe i had the dizzy off so i took it out realigned it and placed it back in. had it right. need some better answers or i'm just going to have to stick with points for a while longer. the mazdatrix thing was not that great. i left the 4 post ballast hooked up per stock as it really didn't say to unhook any of it.

 

mike, get your *** and its infinite wisdom over here.

 

Got the kid this weekend

All I did when I did it was run 4 wires from the coils to the dizzy straight to the coils


Its been a long time, but I doubt thats its really that hard, just look at a 81up wiring schematic. It all should be right there

I can help ya Monday night

 

i followed the m.t. write up on a friends 79 and it had the best idle i have ever heard on a 12a... it pissed me off my car cams/ lobs @ idle but its somewhat of the port

 

damnit. i had the wires left coming off of the igniters. took those and pulled them over to the coils. i took the two external resisters and put the wires on the bottom studs for a simple connection for them. i left the third with all its connections intact as that is what the paper appeared to call for. arrghhhhhhhhhh.

 

 

There's really not much to it. Just hook up both coil and ignitor positives on the same circuit and run seperate negatives from each ignitor to it's respective coil.

 

no ****. doesn't appear to be too much but obviously i have something not jiving. a dead tach and cammed idle isn't very good.

 

dead ignitor?

 

don't say that man. it would be a dead leading igniter since that is what my tach reads.

 

oh yeah..... which would mean the car wouldn't run at all... Have you tried driving it?

 

Wanna bet? My car runs on the trailing plugs.

Jeremy, it does sound like you might have a dead leading ignitor. I guess there's only one way to find out.

 

I dunno what the hell they mean about leaving the existing wiring and ****. When I wired mine I removed all that crap (remember the 80 has a crappy box on the drivers strut tower)... All I had was 4 wires running from the dizzy to the coils

And by the way, the tach works off the trailing, not the leading

I think, well I know the 2nd gen does. And my tach was hooked to the trailing coils negative on my 85. Isnt blue significant of trailing?

 

Nope, early models have the tach running off the leading. Reason being the trailing spark switches off at certain rpm.

 

not the 79 mike. yellow/blue is leading and yellow/green is trailing on the newer. yellow/green is leading and yellow/red is trailing on the 79. yet both used the yellow/green wire for tach signal.

revhed- it does smooth out if i adjust the timing completely advanced.

 

sounds like your not timed right to me.... is the vacume advance diafram ajusted right?
