Testing coil with Ohm meter. 2004 TT600RE
 

I've never used an Ohm meter before can someone tell me which settings I'm supposed to be using ?

The setting the manual is asking for is (ohm) x 1K for the spark plug cap and (ohm) x 1 for the coil. as you can see my Ohm meter has different settings, which one do I use for (ohm) x 1K and which for the (ohm) x 1.

I can also use some help understanding the testing procedure below, if the drawing depicted is accurate with the (+) test lead on the sparkplug wire and the (-) on the connector for the orange wire am I testing for Primary winding resistance ? the orange wire goes to the Ignitor unit.

If I then switch the (-) test lead to the other connector for the red/white wire am I testing for the Secondary winding resistance ? red/white goes to the main switch.

I've tried testing the coil on all 5 Ohm settings and these are my results.

2000K = 014 plugwire & red/white
200K = 13.7 plugwire & red/white
20K = 13.74 plugwire & red/white
2000 = no reading. plugwire & red/white
200 = no reading. plugwire & red/white

2000K = 014 plugwire & orange
200K = 13.7 plugwire & orange
20K = 13.74 plugwire & orange
2000 = no reading. plugwire & orange
200 = no reading. plugwire & orange

The 13.7 is ballpark for the Secondary specs but not seeing anything close to the 4 ohm for the Primary leads me to think I'm not testing this thing right, I would really appreciate some help !

1k = 1,000

Just replace the ones in the manual with 2's which are on your meter so
200
2,000 - 2k
20,000-20k etc etc

A coil is a bit of wire wrapped in a coil(duh) so basically it is a bit of wire and should not have much resistance so the scale you choose would be the 20 and it should read real close to zero to be ok. If it is broken or burnt it might read infinite but that is not always the case, electronics is like that

I don't have TT600 info to hand, so stand to be corrected.
From the diagram you've posted and your results, in both sets of measurements you've effectively measured the secondary, which is 13.74k, so that's OK. (Spec is 13k + or - 20%)

To measure the primary, connect to the two spade connectors, which I assume are the red/white and orange you refer to.

Switch to the 200 range.

The reading should be 4, + or - 15%.
That is, between 3.4 and 4.6.

When measuring this low a resistance, make sure the connections between coil and Ohm meter are clean and firm, as a dodgy connection can alter the reading.
Also, check the battery in your meter is OK (normally there'll be an indicator to show if it isn't).

Hope that helps.

Thanks McCrankpin and TravellingStrom, the coil seems to be ok I'm getting readings of 14.0 on the secondary and 4.5 on the primary, however I'm not sure about the stator coil, I'm using 200 on the Ohm meter and getting readings of 01.1 on both the wires they want tested, the manual wants a reading of 0.65 +- 20%. I wish they had high and low numbers but thats all they list, does 01.1 mean the stator is bad ?

No. Not bad just 'offset'.

Connect the two meter leads together - it should read 0.0, but may read 0.5... that reading (for example 0.5) should be subtracted from your other readings on that 'scale' so for my example 1.1 would become 1.1-0.5 = 0.6. Why the offset? Well in part it is the resistance of the leads.

High and low numbers .. well the things you are 'reading' are made of copper .. and copper changes its resistance (reading) with temperature.. so the stators reading will be significantly different if you measured it 'cold' at say 10C and 'hot' after the engine has reached operating temperature at say 110C.

--------------------
What you have been testing is called continuity - do the ends of the wires connect to one another?

The other thing you will want to test for is insulation. Does this wire connect to things it should not? The stator wires should not connect to the engine/frame.. that is it should be a high resistance .. say over 90k ohms ... ok?

Thanks for the explanation Warin, my meter sits at 1 on any of the ohm settings and like you say goes to 00.5 with the leads connected together, tonight I was testing the pickup coil which asks for a setting of (ohm x 100) so I used the (ohm x 200) setting but couldn't get a proper reading, the numbers would jump around then show nothing at all, switching to the (ohm x 2000) setting gave me a reading of 243, the specs are 230. so far everything I've tested seems to be up to spec, the search continues...

What is the problem?

If it only occurs when it is hot ... then put the coil in a plastic bag and submerse that in hot water .. then test while warm.
