ok recieved this in the mail today

 

its a bosch ignitor 9 222 067 021

 

it has 4 prongs, one with 3 above it one with 7 above it and one with 15 above it and one with 16 above it

 

where do i connect these prongs too, is it 2 to dizzy and 2 to coil, if so which prongs go where?

 

 

edit - found it

so if you need it that will tell you.

 

 

2nd edit - actually, so does 3 go to neg side of dizzy and 7 go to pos, then 15 goes to pos side of coil and 16 goes to neg?

 

and how do i know which side of dizzy is pos or neg? as it doesnt say? just has 2 wires coming out of it

 

and where do i put the 2 vacuum spots on the dizzy as original dizzy only has one vacuum spot.

 

 

3rd - i did it today, used the 4ac wiring diagram in the faq

 

but now the tacho jumps everywhere under 3000 rpm?

 

how can i fix that?

 

Cheers.

New tacho time :)

haha, its not the tacho, i have a feeling its cause i took off the ballast resistor so its giving it 12v continusely to tach, then when you go over 3000 your giving it more electricity than what it gets at idle kinda thing so it works

 

but yea, trev said theres a variable resistor i can get for em, just have to find out where

 

cheers

ballast resistor or not, shouldnt affect the tacho. I had the same tacho on a hilux 22r motor (electronic ignition, no ballast) KE25 (points, ballast resistor) my WB One Tonner (HEI, no ballast resistor) and for a short time my ke30 (points, ballast resistor). I have a feeling theres something not right with the signal its getting.

yea true, its weird aye it works over 3000 rpm but jumpy under

 

trev reccons i need a variable resistor on just the tacho wire

 

hope i can get it working, if not ill get a nice monsta white dial one.../even though my current one has custom dials already....

You might find this post some help.

trav, do you know how to use the edit button? 4 posts in a row is *** ridiculous.

 

I don't want to see 4 posts in a row from you again....you should know better. Consider this a friendly warning.
