Without a functioning 200 ohm resistance range your testing will be somewhat limited, however try measuring the resistance between the blue/yellow wire that connects to one ignition coil and the black/white wire that should also connect to the ignition coil and the between the yellow/blue wire that connects to the second ignition coil and again its black/white wire. Both results should be infinite resistance. If the 200 ohm range was working you could also measure the primary resistance of both ignition coils to make sure neither had developed a short circuit.
other than the ignition control unit simply failed.
Between the coil wires I'm getting no reading, I'm on 2000ohms still tho will this make a difference, this is with my new ignition control unit fitted and the old burnt out one, it makes no difference I get the same reading!!

Your battery voltage readings suggest the accuracy of you multimeter is not good, best to wait until the new one arrives before making any more measurements.

Ok new multimeter turned up getting 11.9v across the brand new battery and 12.9 across the a123 battery.
If I test the blue yellow wires and black wires I get .08 ohms at 200this is with the icu unplugged and with one prong from the multi in the plug that the icu goes into and the other prong on the female blade connector that the coil plugs into.
If I plug the cdi in and measure with a prong on each female blades of the same coil I get no reading this is with a fresh icu amd not my presumed dead one! Should I be getting a reading when doing this?

Assume when you say black wire you mean black/white wire, your 0.08 ohms readings says continuity for these wire is ok.
Loom tests:
1. Set meter to highest resistance range. Put +ve probe on the yellow/blue wire and the -ve probe on the black/white wire. Measure resistance.
2. Set meter to highest resistance range. Put +ve probe probe on the blue/yellow wire and the -ve probe on the black/white wire. Measure resistance.
Ignition coil #1 test:
1. Set meter to lowest resistance range and put +ve probe on one primary terminal of ignition coil and the -ve probe on the other primary terminal. Measure resistance.
Ignition coil #2 test:
2. Set meter to lowest resistance range and put +ve probe on one primary terminal of ignition coil and the -ve probe on the other primary terminal. Measure resistance.
DUD TCI tests:
1. Set meter to lowest resistance range, place +ve probe on TCI pin that would normally be connected to yellow/blue wire and put -ve probe on TCI pin that normally connects to green wire. Measure resistance.
2. Set meter to lowest resistance range and place +ve probe on TCI pin that would normally be connected to blue/yellow wire and put -ve probe on TCI pin that normally connects to green wire. Measure resistance.
3. Set meter to highest resistance range, place +ve probe on TCI pin that would normally be connected to yellow/blue wire and put -ve probe on TCI pin that normally connects to green wire. Measure resistance.
4. Set meter to highest resistance range and place +ve probe on TCI pin that would normally be connected to blue/yellow wire and put -ve probe on TCI pin that normally connects to green wire. Measure resistance.
5. Set meter to lowest resistance range, place +ve probe on TCI pin that would normally be connected to black/white wire and put -ve probe on TCI pin that normally connects to green wire. Measure resistance.
6. Set meter to highest resistance range, place +ve probe on TCI pin that would normally be connected to black/white wire and put -ve probe on TCI pin that normally connects to green wire. Measure resistance.
Battery voltages are a low and in need of a charge. Lead/acid battery should be 12.8 volts fully charged and A123 closer to 14.5 volts.

Yep I do mean white black
Loom tests:
1. Set meter to highest resistance range. Put +ve probe on the yellow/blue wire and the -ve probe on the black/white wire. Measure resistance.
With the icu connected to the loom I get no reading regardless as to where I set the ohm scale on the multi, it just says one all the time right on the right hand side of the multimeter
2. Set meter to highest resistance range. Put +ve probe probe on the blue/yellow wire and the -ve probe on the black/white wire. Measure resistance.
As above
Ignition coil #1 test:
1. Set meter to lowest resistance range and put +ve probe on one primary terminal of ignition coil and the -ve probe on the other primary terminal. Measure resistance.
Ignition coil #2 test:
2. Set meter to lowest resistance range and put +ve probe on one primary terminal of ignition coil and the -ve probe on the other primary terminal. Measure resistance.
The coils ain't with me they are on the bike still, I will check these and report back
DUD TCI tests:
1. Set meter to lowest resistance range, place +ve probe on TCI pin that would normally be connected to yellow/blue wire and put -ve probe on TCI pin that normally connects to green wire. Measure resistance.
Getting no reading, it randomly flashes up a reading when I first touch the probes in the pins but it's Very different Everytime this is on the suspected duff icu and both the good ones, this is the same for the other tests you have suggested for the icu
2. Set meter to lowest resistance range and place +ve probe on TCI pin that would normally be connected to blue/yellow wire and put -ve probe on TCI pin that normally connects to green wire. Measure resistance.
3. Set meter to highest resistance range, place +ve probe on TCI pin that would normally be connected to yellow/blue wire and put -ve probe on TCI pin that normally connects to green wire. Measure resistance.
4. Set meter to highest resistance range and place +ve probe on TCI pin that would normally be connected to blue/yellow wire and put -ve probe on TCI pin that normally connects to green wire. Measure resistance.
5. Set meter to lowest resistance range, place +ve probe on TCI pin that would normally be connected to black/white wire and put -ve probe on TCI pin that normally connects to green wire. Measure resistance.
6. Set meter to highest resistance range, place +ve probe on TCI pin that would normally be connected to black/white wire and put -ve probe on TCI pin that normally connects to green wire. Measure resistance.
Battery voltages are a low and in need of a charge. Lead/acid battery should be 12.8 volts fully charged and A123 closer to 14.5 volts.
The lead acid has cranked the bike over for maybe 30sec max, the a123 a little more maybe
Thanks for the reply Maggs again really appreciate it but i must be doing summat wrong as I can't get any readings, I'm fast turning into xiliva with this thread!!!

Many pages to go before reaching that state and confident we never will.
A quick check of your multimeter, you do get zero resistance with +ve and -ve probes touching and infinite resistance when probes are not touching?
Ignition coils test is easiest, one probe on each of the terminals (lugs) that normally connect to the black/white and yellow/blue wires. Should measure resistance of 2-4 ohms.

ok magg this is my multimeter, its basic and shit i know but it should do everything i need to wont it after all it did cost me £3.29!!!! man i am cheap.
so if i set it to the 200 Ohms so pointing at 6 oclock plug the cdi into the loom but have noting else plugged in then test the two spades that connect to the loom i should be getting a reading?
Currently im not, if i place the +ve on the black white wire to the front loom and the -ve to the black white wire on the rear coil i get a reading of 00.6.
so i have continunity of the live out of the icu. im guessing that by plugging in the icu i should have a complete circuit from black/white into the icu then back out to the blue yellow? but im not getting any readings, which is begining to get annoying.
this weekend to cheer myself up and restore some faith in myself i am going to strip and rebuild my calipers with some fresh fluid and red rubber grease. why oh why am i such and electrical retard!!!

Together on 200ohms
Apart on 200ohms
this is the reading i get wehn on the black white and blue yellow spades of the same coil with a good icu plugged into the loom but noting else plugged in, do i need the rhd run off switch gear attached?
I cant test the coils as they are on the bike still but i will test this weekend and report back.
