My Brompton's bottle dynamo, an AXA hr, has 4 brass tabs to which the wiring is attached via a four-holed plastic bar; the wires are simply poked through the holes and then the plug is pushed onto the 4 tabs.
I get intermittent contact, resolved by patting the plastic bar, which
lasts an unknown length of time.
Should I
1- chuck the plastic bar and try and solder direct to the tabs? 2- chuck the plastic bar and try and solder connetors onto the wires and push those onto the tabs 3- ram the plastic plug on so hard that I am sure it is munging into the twisted wires that I somehow got through the holes, but am worried I will bust something?

Or:
4- see if the tabs are a standard size for crimp spades, and if so, use them instead.

....and crimp connectors can be soldered if you don't have a proper crimp tool, and by 'proper' I don't mean those cheap plier-type things that Draper and everyone else make :-)

I did this. I think I also combined the wires for the front and rear lights. A dab of silicone grease (not silicone rubber), and it's been working like a charm for the past 4 years.

They are a bit thicker. My solution was to slightly spread the entry of the crimp spades with the tip of a corkscrew, then shove them on with a bit of force. Has been working well for about a year on two bikes.
