12v to the coil, when running it's around 9v across the two terminals.
Guy you need to check the primary resistance ohms of the coil to see if it is a 9v or 12v coil, do this by setting your meter to ohms and connecting the test one lead to the VE+ terminal and the other lead to the VE- terminal on the coil. Did the coil come with the engine and has it got a name and /or numbers on it so we can try to identify it.
On my meter I have Ohms x10 or x1k, not running it's got just over 1 ohm on the x10 and just under 1 ohm on x1k
But I have no idea what either means... :beuj:
That sounds to me like you have a ballast resister coil. What I can find out ballst resist 1 - 1.5 ohms, non ballast resist around 4 ohms going to go and do some checks in a little while and will let you know. Just checked a known ballist resister coil and it is 1.2 ohms. Think I have got a non resister coil in the garage somewhere if I can find it I will let you know. You can run 12v through a ballast resister coil though I an sure after a time it will burn it out.
You could fit ballast resister with extra wiring or fit a new non ballast resister coil
Do not think running a non ballast resister would cause the problems you describe so if in you have checked the rest of ignition system till you fit a ballast resister or another coil I would look at what has been advised about the carb and transmission
Found the info I was looking for, if you look on this site look at the different primary ohms for Lucas DLB 102 ballast coil and Lucas DLB105 Non ballast coil. They also do the ballast resisters. http://r.search.yahoo.com/_ylt=A9mSs...7hh2aHSr6jpQI-
Deffo looks like I was given the wrong coil then, the old one is deffo a ballast one, as it says so on it!!!
Looks like my birthday money will be spent on a new coil, and another rebuild kit for the carb...
Thanks again Paul :tup:
Guy the way I look at it is that what this community is about helping each other when we can. Let us know how you get on. Cheers Paul
If you have 9v TO the coil when running, you have a ballast resistor in the circuit surely. In which case you are supplying a 12v coil with 9v.
