Baffled, breakdown and no idea of the cause.

If the fault is completely at random with no logical reason it could be the hall effect distributor. I had one which had the white circular piece of plastic with 8 ferrite rods in the plastic. It took ages to realise that it was playing up. The later VR distributors are the ones to have.
Update. Took the ignition amplifier module off the car and took it down to the local motor factors who tested the amp and coil which are both working fine with a good strong blue spark. The lad behind the counter is a time served Rover mechanic and he believes its 90% probably the condensor that's at fault so a new one on order and I'll try it tomorrow so fingers crossed it works or no rusty nail for the wedge this year.

How very strange. The job of a condenser is to reduce the spark so as the points don’t get burnt or pitted. An electronic ignition system that has no points and has a module, shouldn’t need a condenser, unless I’m missing something. Still, change it and see if t makes a difference. I can’t wait to hear the result. Good luck.

Found this on a previous thread from our old friend Ramon of the Vintage model aeroplane SD1 site...
A Condenser (or Capacitor) connected into the low voltage circuit across the coil/amplifier combo to suppress Radio Frequency signals otherwise destined upset in-car entertainment systems and offend un-neighbourly soap addicts watching their TV’s. It is also perceived to assist in rapidly collapsing the coil primary voltage for a sharper high voltage discharge.

Further investigation revealed its a radio supressor not a condenser as first thought its been changed and no difference. Next port of call is the coil which is on order and will be fitted later today, ordered a bosch one which was a bit pricey at 50 quid but germans always better. Gunna fot that when it arrives as the spark is still yellow when the king lead is detatched and arced onto to rockers. So if that dont work I'll have a look at the dizzy when this mental wind stops.

I have recently had a coil failure (and an ignition amp failure for that matter).
I ordered a genuine Bosch coil at a similar price, so three times the cost of a cheapy.
A month later it left me by the side of the road as the coil was arcing everywhere other than down the king lead.
Supplier was very apologetic and sent a replacement promptly, which, so far, has been OK.
Both mine appeared to be original Bosch with the distinctive "made in South America" stamp on them. When you get your new one, post on here where it says it was made.

Yup made in south America. You were right DUNC.I ordered a genuine Bosch coil at a similar price, so three times the cost of a cheapy.

Ahh but if there's a spark at the king lead it's not the ignition amp (at that point in time anyway).
If you have changed the rotor arm recently then the new one might have failed. I had one fail after only a few thousand miles.
I agree with Adam on this as it does sound like its either a bad rotor arm..or the wrong one...Red is no good, well it wasn't for mine, the rotor arms with the riveted plate can fail and are recommended against using on RV8 forums......You sure there is no more carbon tracking or possibly cracked dizzy cap...If you have changed the rotor arm recently then the new one might have failed. I had one fail after only a few thousand miles.
Ziga
I used these and have been fine for two years.....
