GS750 - Points Problem

[JT-NZ]

I'm fitting a points system back on my 1979 GS750E but something weird is happening. Instead of the voltage at the points disappearing when they open, I'm actually getting 10 volts when the open and no volts when they are closed. When I disconnect one of the coils I get 12 volts at the points when they are open.
I've checked everything connection wise and the only thing I can find is a high resistance reading on one of the (aftermarket) coils - 9 ohms with the coil rated at 3.9.
I've doubled checked the points plate and everything is wired and insulated as it should be, but the plate itself is definitely getting voltage as it sparks if you touch it against the engine.
Any ideas ?

Found the problem ! The bracket at the end of one of the condenser wires was bent/twisted and was just touching the post that the signal wire attaches to.
Only found it by the use of a magnifying glass.

Good find. The points are good in my 750 and I have a new set of Suzuki ones for next time. Mine had bad condensors which I replaced. Simple system but it still requires a bit of maintenance.
