Title: dynamo split bullet connectors
Post by: David Tinsley on 10.08. 2022 01:00
1955 GF SA
When fitting the split bullet connector to the dynamo output the connectors themselves are a loose fit. (The connectors were supplied with the new loom I have fitted.)
I think I read somewhere that the bare wire is meant to wrap around the connector, but this seems like a bodge way of getting a good connection. Is that the correct method or am I missing something obvious (which is quite possible!)
Cheers,
Dave

Stripped wire goes through end of connector and is draped down over it. Wire strands make up for the connector loose fit.

It works but it does seem a bit amateur.

I've noticed that the split connectors supplied new now are under-sized compared to the Lucas-supplied items from way back when.
Little pieces of shiny tin sh*te compared to how Lucas intended the connection to be. The original connection, though a bit rough-and-ready, was substantial and worked well. Same goes for the reg connections.
Often see the paxolin plate and the rubber boot missing too now....just two bare wires stuck into the back of the dynamo. *eek*

I use standard blue crimp bullet connectors - they are a good tight fit and fit nicely inside the end cover.

Thanks for all the replies. Seems like I just need to figure out a secure way of firmly connecting the wires. At least I know now that my confusion was somewhat justified. I thought I was missing something obvious.

The idea is that the plate screws on and holds the bullet connectors hard against the females that are embedded in the endcover, note thats why the bullets are swaged.

So, if I understand correctly, I remove the end cover of the dyno, then fit the output wires, then refit the cover? (I am not out in the shed to look right now, but will tomorrow)

No, there is a phenolic plate that just fits on the connection plate, holds in the split bullet connector, and then is held with a screw. A rubber boot is then fitted over the phenolic plate and the wires.
I will be in my shop later if you need a picture but it is pretty straightforward.

That does not sound like the set up I have. I have a cover on the end of the dyno with two holes for the wires, no rubber boots. If you have a photo that would be great.

if you Google rubber lucas dynamo rubber cover (or somesuch version of the words) you will get a pic of the cover as many vendors sell them, and when you see it it'll be obvious how it fits on the dynamo.
Apart from waterproofing the connection it looks much neater than two wires poking out of the dynamo end-cap.

Thanks for those pics, now I get it. I do not have that boot or paxolin piece. I shall look at getting them.
Cheers

The rubber boot is actually a cooling device which holds water to chill the wires as they exit the dynamo, they will also form a nice coat of rust which will keep everything together. *smile*
You are a funny man 👍

Thanks for all the advice and tips. I now have the parts I need on order, including the "cooling device" boot !
