Reg, you say the problem is only there when the coil is warm then the the coil is farked

Thanks again for all your helpful comments. I've just checked the coil with a multimeter and got a reading of 3.8ohms on low tension and 7.2 on high (with meter set to 20k). Methinks this to be rather low. My hand will now have to be delved deep into pocket for wine/beer tokens to exchange for new coil.

Just thinking things through and can't help wondering if the original coil was compatible with the Eureka Electronic ignition I fitted. It seems some coils are not suitable for use with electronic systems. Anyone had similar problems? I fitted the Eureka after having two condensers fail in rapid succession, and thought it a good idea at the time. I'm now considering reverting back to points. Electronic ignition is supposed to be ""fit and forget. Or should that be "fit and keep your fingers crossed."

On this type of bike the point's are my favourite, electronic, fit and forget?, electronic goes awol you get taken home, point's problems, you can usually ride home and sort it.

After the continued troubles the shyte 1990s coil & points was binned and replaced with Boyer that was fitted & forgotten 20 years ago

Hi guys--------Hi REG, now you can kick my rumpsteak if you like--- and I realise my next comment comes after the event but a look at page 89 of our hosts current catalogue shows the Eureka kit at £85.80 whilst the Boyer Bransden Mk.4 system is at £78.....Just saying, that's all..... Maybe you can off-load the Eureka via a certain "? Bay" then buy and fit the better product ??----Incidentally my 2004 Bullet '65 has Boyer Mk4, PVL coil and irridium plug with brand new VM28 Mikcarb...and starts on second or third prod OR first time with the starter motor....Incidentally our hosts have a new-ish VM28 for £50 )...

Point taken Alan. (No pun intended) I must admit to buying the Eureka kit from an Indian supplier a couple of years back for about £40, and have no problems with it as such. It did what I bought it for,namely to get rid of the troublesome condenser. I wonder though if any electronic system is compatible with the standard coil, or whether this should be upgraded whilst fitting making such "improvements". It seems that some coils used on classic cars are for points ignition only. Not that I claim to have any expertise in this field. Anyway a new Lucas coil is on it's way from our hosts, and I am seriously thinking of going back to the old points, and perhaps carrying a spare condednser in my pocket.

To be honest REG that's what we used to do back in the day !!-------Nowadays they are saying carry a spare detector head with you !!........

Hi Reg

I don't know about Enfields but the coils for the Suzuki GT500 which have electronic ignition are different from the coils for the earlier 500T which had points ignition.

The following may help you with the values you might expect to get when testing coils

New coil fitted and bike started reluctantly, then died. After many attempts the same result was achieved. Good spark at plug, so checked fuel line. No flow. Poked a bit of wire through fuel pipe spigot, and bike started first kick and revved enthusiastically. So after all that, it was fuel shortage. Got me thinking that bike maintenance is a bit like playing roulette: It's either electrical (red on the roulette table), or fuel (black on the roulette table). I put my chips on red, working on the principal that carburetor problems are usually an electrical issue, and the ball lands squarely on black.Oh well, some you win, some you lose. At least I have a spare coil now. Thanks for all comments.
P.S. Thinking about using dice as a diagnostic tool for the next inevitable problem.
