Wondering how it can be flat again so soon after the last charge, so I came back here to find it was almost 4 weeks ago. A couple of observations while charging:

The ancient dashboard charge meter is completely undamped and wiggles vigorously for a couple of seconds after any current transition, so after switching on I expect it to wiggle, but I find it continues to wiggle for the next ten minutes. It looks to me that the current is varying randomly, would I be right to assume this is caused by bubbling in the electrolyte? It eventually settles down.

After half an hour, when I got close my forehead could feel radiant heat from the charger. The rectifier bridge was gently warm on its heatsink, but it was the transformer that was glowing hot. Transformers are normally bolted firmly to a stout chassis, but the expedient construction here gave no heatsinking. Caught me out, so I've now added some sheet aluminium and painted everything matt black. Now it can wiggle away 'cool'
