well my uncle dropped of my 83 rx7 yesterday and when i went out and was messin with it...when i revved it the tach would read above 2800-2900 but the motor would rev higher...then i went out there later and started it and the tach just didnt work..so i wanted to try and move the wire from the trailing ignitor to the leadind to see if the tach will work....so where are the ignitors? pics would be great

 

The 2 small black boxes on each side of the dist. Leading is facing towards the front.

 

ok..img going to go look...which is trailing and whick is leading? is there just a wire on the trailing for the tach?

 

Ignitors are the 2 square black boxes bolted to the side of the dizzy with wire conectors coming off of them. Can't miss them. Check the wiring diagram in the FSM for the tach wire. Link is provided in my sig line.

 

Both trailing and leading are the same so your headded in the right direction. You cant miss them as they are on the distributor by the distributor cap clips..... Sorry no pictures here

 

thanks guys....im going to good look right now....which wire do i switch over?

 

Read the FSM, you will learn more that way.

 

i tried....***** confusing......i switch the plugs on the leading and trailing ignitors and the tach still didnt work....u guys think it could be because it is cold here?
