Power Supply to Dizzy

[Wheeto]

Hi,

Got a 998cc on a M plate, had an intermittant misfire, basically cutting out at idle. Ran for a while like it then died altogether.
Have got no spark, so replaced the dizzy with a brand new item. One of these ones: http://cgi.ebay.co.uk/NISSAN-MICRA-...arts_Vehicles_CarParts_SM&hash=item4144e20b6b
Looks slightly different to my old one, the body of the dizzy that sits inside the crank case seems to be bulkier, and my old one had an external condensor. I'm guessing I could use either part?

Fitted it anyway and still no spark, got a multimeter on the plugs that connect to the dizzy and I'm reading no power on all wires when the ignition is switched on.
Just wondered what wires should be showing voltages and what else should I be doing to diagnose the problem?

Cheers
Scotty

hi scotty, you should have 12v at pin # 2

Thanks for the diagram, I'm guessing thats with the ignition in the On position?

From when I tested it I don't think I have power at any of the pins :S

 

[Noddie]

yeah, thats with key in the on position
A blown fuse maybe?

 

[Wheeto]

all fuses appear to be intact, when I turn the ignition on I get all the dash lights as normal, just wondering if there is a relay that supplies the power to the dizzy?

 

[frank]

it looks like it shares the same feed as the injectors scotty, are they showing live ?

Thanks for the replies guys, will check at the weekend and get back to you, been a tad busy!

Ok, So I double checked the reading today and this is what I got.

Voltage across the battery was 11.6 V cause its a little flat

Does this look about right? How close does the timing need to be to get it to fire, im used to vws where they'll fire up with the timing way out, and what is the correct timing for it? Got a strobe etc just not got my manual to hand

Yeah, that looks normal as far as i can remember but dont think the 10.8V reading is right but not sure.
whats the resistance between the two pins on the smaller connector (dizzy side)? should be around 0.8 ohms
