do i need the stock 8 spark plug distributor in order to get both coils to fire on z22 ?

[720kingkab]

or do you mean test module leads for 12v ?

i did that with key on and off 

all wires have 11.44 volts when tested 

 

let me get a photo posted 

hang on 

 

Yah I guess they would read something though the coil primary.

 

OK remove the wires from the positive terminals of both coils. Pull the wires off the module terminals and test for 12v. The one with 12v should be on the middle terminal.

[720kingkab]

the pix with dmm are all with key in on position

[720kingkab]

where is the device that turns off/on the 2nd coil

on/off during deceleration or slowing ?

is it on carb or throttle linkage

and i failed to hook it up ?

or it is stuck ?

 

or maybe i have a vacuum line on wrong

and when motor starts

it is holding 2nd coil in off mode ?

ok

with both coil + wires removed

and all 3 wires removed from ign module inside dist..

 

the center black wire with white stripe 

is only one with voltage

it is 12.77v

[720kingkab]

there is a vacuum hose

going to a diaphragm on distributor body 

 

that vacuum hose that is taken off

when timing is set

like these hoses maybe ?

[720kingkab]

 

[720kingkab]

maybe if i start engine

then start pulling vacuum lines

the 2nd coil might come on ?

[datzenmike]

NO don't mess with it. If your module only has 3 terminals don't worry about the shut off. You don't have it.

 

OK 12v on center wire so it's wired correctly.

 

 

 

That's the vacuum advance hose. There is only a vacuum signal above idle so as long as you have 700-800 RPM idle then there's no need to remove it when setting the timing.

[720kingkab]

the trucks runs and drives really nice .

just hard to start when really cold

 

maybe hard start related to  2nd coil no worky ?

 

i will know more about new coil performance

once i try and start when really cold tonight
