Thanks everyone for the info and healthy debate.  

I knew I had the answer somewhere then remembered the box of papers and documents that sits sealed up in the attic from when we moved house 13 years ago.  Inside was all my collection of Bantam info and a treasured copy of the Wipac Series 55 magneto generator info.  Anyway Julian S has beaten me to it and the DC wiring circuit corresponds to my switch gear.  There is a topic elsewhere on the forum about a Wipac aftermarket 'stoplight' kit which discusses the significance of the resistor wire.  As for the resistor value, well.... I should have payed more attention in the science lessons instead of gazing out of the window watching trains puffing along.

Will try and get the tank cleaning pictures uploaded.

Dear All,

Time for an update.  Decided to raid the attic and bring down all my old files.  There's plenty of Wipac manuals and BSA service sheets which without cluttering up this blog, I'll find other ways of passing it on to the Bantam club.  Service sheet 810A for instance provides some useful info on flywheel generators.

I've re-wired a D3 before using trailer cable wire and shrink-wrap. I didn't include any form of resistor but never had any problems with over-charging batteries. Maybe I ran with the lights on from time to time. I'm too miserly to buy any of the pattern wiring looms on offer at autojumbles which I thought were a bit over-priced. Here are some pictures of de-rusting the petrol tank with black treacle. I've since been painting and lining the tank so another installment is coming up.

Black treacle! I've not come across that before. I've used vinegar and electrolysis successfully though.

The dove grey of that particular D3 is the best (IMO), not just because I have one too.wink

I have mentioned black strap molasses here before.I used it on frail mower sheet metal,with good if slow results.The process is chelating.Treacle is a novelty though.There is a need for sulphur in the agent which modern molasses does not have.
