Having a little issue so decided to check the coils primary came up 02.0 secondary 32.21 and the HT leads disconnected 4.25 which is what threw me i found the reference to the others but not the leads, all 3 coils hovered round the same any help much appreciated
 
are u checking with the ground side disconnected other wise you might be checking through the ecu.
4.25 ohms on the ht spark plug wires is great.
because all three checks the same i would think they are good.

See step 6.

Ok, disconnect the 2 low tension wires at each coil. Check resistance between the two terminals The result should be within the spec I already shared. Make sure the low tension leads are a snug fit on the terminals (a known problem area). Check all three coils. If you had a high tension problem, I believe it would likely throw a code.

pictures and simple is the way i would go but if there was a dummy that had cut a bunch of wires then i would go with the rocket manual to repair it.
checking it by the manual may or may not find a lose connector.

I have a few loose connections when it comes to electrics I do admit hence the poor explanation

Thanks for that to be honest I have never used a multimeter before... I see it now and my question is it ok to be point 2 above the higher reading of 1.8

Thanks for the reply, I see it now the question is it ok to be point 2 above the higher end of 1.8

Cheers for that, to be honest I haven't used a multimeter before, my question now is it ok for the primary to be point 2 ohm above the the 1.8 shown in the diagram

Presuming I've set the multimeter up right my last question is it ok to be point 2 ohm above the higher end of 1.8 ohm specified

A few thoughts, first, you never stated the reason you were looking at the coils in the first place. So I can’t say really if the.2 ohm over limit is really an issue. I doubt it is. Was the reading 0 when the two probes are touch to each other?
I state again, the most reported issue is loose connection(s) on the low tension side.
