My multimeter arrived today (thanks for the link, AWJDThumper), so I checked across the battery terminals and got 6.12 volts. That's okay, isn't it? At the headlight end of things, the headlight bulb seems okay, the pilot light bulb has blown. Ordered new one. Didn't notice anything of concern around there. Struggling to attach photos. My Paint3D is difficult to fathom. Phil (novice.)
