Tatton Park at the weekend, I won an award - 2nd place rare car - was chuffed to bits.

The small autojumble yielded some useful spares, including a new AC petrolift, Minor quarterlight, battery terminals, screen washer bottle bracket, and a new seal for my brake master cylinder lid.

I had been searching for a Negative Lucas 'helmet' battery terminal so I could put the Humber back to 'factory' specification, this is important to me and has included hunting down things like the correct Lucas torpedo 35 amp fuses. This is all done for myself, as I never enter competitions for prizes, that's not my thing. This weekend's prize was awarded by a judge who takes his pick of all the vehicles there.
So I had two of the correct battery terminals.

I lopped the end off the Negative, these are from the days when British cars were predominantly Positive earth, of course mine was until someone decided to change it, possible due to radio fitment, and binned the original terminals instead fitting SMMT type.

After the last disaster where I tried to un-join the wire from the clamp and ended up melting the lead terminal, a different approach was called for, viz. sawing off the lead and drilling out the remains, ready to inset the braided earth lead.

Time for fire and flame.

Soldered the starter switch terminal, doesn't look the best but a solid joint and I was wary not to use too much heat as the insulation (this for the Positive lead) was getting a bit soft.

Remember my old coil purchase, which on closer inspection had a hole in the aluminium case? I patched it up as one member suggested. It showed good continuity across the low tension terminals so there was no reason why it would not work, but they are filled with oil to keep them cool, and if this somehow drains out, well...
I removed the newfangled Valeo coil, which in fairness
was oil filled itself, as I could hear it when I shook it. So much bad press is given to modern parts but this was fine and I only changed it for originality's sake.

The Lucas coil was also much larger in size. I made sure I got the polarity correct, particularly essential when the car has been converted to Negative earth like this one. Valeo coil is marked + and - but I much prefer the simpler and easier to understand CB and SW. One connection wasn't looking so good.

So I sorted it out re-using the original connection.
