The rotor arm turns, albeit slowly. Ive not disconnected the ignition amp yet and earthed the coil, should I still do this?
Ok This is good, the distributor is turningThere is a problem in disconnecting the amplifier and earthing the coil, you can go ahead and do it ***But*** I doubt very much that you will get a good spark, you will very likely get a weak spark as long as you don't give it too much of a gap to jump across - The amplifier helps create the good spark

You have probably guessed you are dealing with a novice here so if I don't get a spark then I cannot be 100% confident i have done the process right in the first place. I think i will go ahead and order an ignition amp and replace it, if the problem is still there then I've lost £30 and have a spare.There is a problem in disconnecting the amplifier and earthing the coil, you can go ahead and do it ***But*** I doubt very much that you will get a good spark, you will very likely get a weak spark as long as you don't give it too much of a gap to jump across - The amplifier helps create the good spark
A bit more googling says I need a Lucas part and not a cheaper alternative but the only ones I can find are Intermotor and the like. Should I be looking away from the TVR parts suppliers?

Did you pull the king lead out of the disributor cap to check for a spark, another poster did mention this earlier, did you also make sure you held the king lead terminal close to a known good engine earth when checking for a spark?
I did check yes, it was as close as I could get it without actually touching. I put the king lead here, between the two unused bolt holes.I got a new amplifier from these people and they were very helpful.
New old stock, the genuine Lucas article.

It was quite some time ago but probably worth a phone call.
HTH.

They are out there this is new old stock before Lucas got rationalised into generic crap, this is embossed and its knowing what a genuine one should look like https://www.ebay.co.uk/itm/IGNITION-MODULE-DAB127-...

I went ahead an ordered part DAB118 here:http://www.autoelectricalspares.co.uk/lucas-dab118...
Your part no is DAB127, anybody know which is correct?
edit ignore me. I read the DAB127 but see you've ordered DAB118 which I think is correct. I ordered this part which is DAB118 too.

There are basically 2 modules- a two and three pin. The function is the same, but the three pin has a direct earth wire, and the two pin does not. You can switch between module types, but you either need a cable adapter, or make up our own connector if changing between 2 and 3 pin. Having said all that the two part numbers listed both appear to be of the three pin type, so wiring should not be a problem assuming the original is a 3 pin unit.

HT voltage is massive, IRO 35,000v but the current is low so it shouldn't kill you (unless you have a pacemaker...) but it is unpleasant and avoidable.
NG7TX used the word "place"...by that he meant lay the lead so that the end terminal is near (but not touching) a bare metal part of the engine. You might have to weight it down with a tool or prop it up with a rag to achieve this. Ensure that there is nothing easily flammable nearby too (eg petrol soaked rag)

Think the current that would be delivered is certainly high enough to kill you, particularly if it went hand to hand, i.e. one hand holding the lead and another on the engine or part of the chassis/body frame. My friend at school told me her Dad was killed in this way and that was with old ignition systems. Modern ones have much higher voltages, >50kV.HT voltage is massive, IRO 35,000v but the current is low so it shouldn't kill you (unless you have a pacemaker...) but it is unpleasant and avoidable.

I used to test myself with HT Leads to see if I could hold on to them or not, more often than not I was able to hold an HT Lead and suffer the shock, I only ever used my right hand and kept the left hand well away from the car.
