AXA HR bottle dynamo connector

[charles]

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?

Comments and suggestions, please!

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

(Probably 2.8mm crimps, by the way!)

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.
