96 XP Ignition coil test

Question
when I ohm test the primary coil of the ifnition coil I get teh correct reading of 0.6 ish ohms, but when I test the secondary coils I get infiinite ohms when the manual states I should be getting 15k to 19k ohms. the manual also states it should read 0 ohms if the coil is busted. FYI, Im using aharbor freight meter I bought on sale for like $4.

My ski has a bad CDI or busted pickup coil so I cant test it on the ski. Seems to me that since it is getting an ohms reading on the secondary coil that it is good, but I wanted to check with you guys first. Anyone have experience with this?

then it's "open". Time for a new coil.

Though that may suck, at least you have an answer.

Not knowing what is wrong is MUCH worse than knowing,,, (Maybe not cheaper though....)

Resistance should be between 0.34 -0.62 across the two spade connectors where you removed the black and white connectors for the primary side. You got 0.6 so that passes.

Secondary side:
You need to remove the sparkplug boots and check this thru the sparkplug wires. One lead to each wire you should get a reading between 9-15K. If your meter read 0 then your secondary is shorted. BUT I would first cut back both ends (boot side and coil side) and set your Harbor meter to 20K range on the Ohms and retest.

When you say infinite does the meter stay at 1.____ and if you touch the leads it should go to 0.00 Post your results. I have the Harbor meter for when I work around environments that are harsh, I don't want my good Fluke getting trashed, been with me way to many years.

For the secondary side, with the boots removed and plug wires clipped back a 1/4" the meter reads 1 in every ohm setting from 200 to 2000k which I though meant the resistance was greater than the meter could read. When the leads are touched together I get 0 ohms (or very close to as the leads themselves have some resistance).

And I haven't had a reading of 0 in any of my testing. The coil appears to be in good condition with no cracks, bulges or anything else out of the ordinary.

Is this the meter your using (98025) or the like. I just tested my coil and I got a reading of 12.43K with the meter set on the 20K. If you flip the dial to 200K your meter would read 12.4K, and then flip to 2000K you'll get 012K. Now if you flip to the plain 200 or 20 position you'll get a reading of 1___. If your meter stays at the 1___ I would pull the wires out of the coil all together and ohm each wire from end to end to verify that they are not broken internally, then if they passed that test I would clip the ends that go into the coil(measure how long they are from the clip so you know how much to push back thru before you clip it back in) and then re-insert them into the coil. Now try again. If you still get the same thing, try a different meter, 4 bucks is cheaper than a coil! If the other meter gets you the same results, buy a coil. These meters are OK, but what do you expect for 4 bucks, I got mine for free with a $9.99 purchase.
