Update: well as at 27th November it still disarms at two seconds, without any more charge into the battery.
But I haven't finished yet. I'm going through all the main connections. I've done the battery, which was OK. The battery earth is bolted onto the battery cradle cross-member. This is bolted onto the chassis. and locates above the lower rail.
I don't know if the holes for the battery cradle crossmember are drilled before the autophoretic coating, but I do think having this arrangement may cause trouble later on.
So today I've added a supplementary earth lead from the battery cradle pivot bolt, to the fixing bolt on the chassis. I scraped away a bit of the coating under the penny washer to get a good contact, and tested it for continuity.
Tomorrow I'll look at the other main earth contact points. There's one in the spare wheel cavity in the offside corner, and two onto the bulkhead above the brake servo.
