If the voltage is low as I suspect you may have a bad converter, or when you attached your ends and did the heatshrink you got a short, and the converter is shutting down to prevent damage. (Do we know if it has this feature?)
If it doesn't have such a feature it might be that you have a bad converter because of a short damaging it. I'd definitely double-check all your connections in this case and make sure there are no shorts and see if that resolves your problem.
If you measure a high voltage (like 7.3V or so) at that current.. I'm flabbergasted?
I wouldn't personally be too concerned about the 7.3V, some SMPS and even linear regulators float high without load, just because it didn't occur when I checked it doesn't mean it won't.
Do report back please, I'm curious how this works out,
