I find a canadian tire DMM on there site who do duty cycle, it was advertised at 59.99cdn here's the link:

http://www.canadiantire.ca/browse/product_detail.jsp?FOLDER%3C%3Efolder_id=1408474396672790&PRODUCT%3C%3Eprd_id=845524442202151&bmUID=1231359314548&assortment=primary&fromSearch=true

So I was ready to pay that price, I drive to the nearest store and pick one. When I get to the cash the girl say, you're lucky this item will be in sale tomorrow, I'll give you the special price 24.99 cdn, do you need a batterie with this?

Yes sure...

Here's the test I do with the DMM

Duty cycle test:

Outside temp: -1C°

Engine cold:

diagnostic socket X11 (9pin round socket)
Pin2 ground
Pin3 red

49% no on/off

IACV: 72%/73.6% on/off

Engine at 50C°:

Diagnostic socketX11:
62%/68% on/off

IACV: 72%/73.6% on/off

Engine at 80C°:

Diagnostic socketX11:
62%/68% on/off

IACV: 72%/73.6% on/off

I do not unplug the IACV to do the test.

Since none of my shop manual or cd have the procedure for m 103 1991 2.6. the procedure in my book are for model without a MAS realy. The only thing I have is a wiring diagram for my model.

Who know what those result mean??

Anyone have the procedure for my model ??

Thank for you help
