Morning all, You will of course be on the edge of your seats. Here is the next thrilling instalment. Berniej's suggestion for testing the ammeter (no doubt absolutely obvious to him, but to me a great revelation) was very useful. I put a little bit of wire across the two ammeter connections, watching the headlight out of the corner of my eye, and...the gloom was not lifted. So, I thought, maybe it's not the ammeter after all. Then, whilst fiddling around to make sure my bit of wire was making a reasonable contact, I noticed the rear light come on! Hallelujah! But why no headlight? I kept fiddling with the little bit of wire. Then the parking light came on. Then it didn't, even when the rear light was on. So I guess that's a bad connection somewhere for the parking light. But still no headlight. So I thought I'd check the headlight bulb again, and when I took off the bayonet-like fitting I saw the bulb was crooked in its hole, so maybe there wasn't a connection. Then, trying to straighten the bulb, I broke one the bulb contacts off (I have a feeling I've done that before) so I need a new bulb. Anyway, to sum up at this stage, it looks like: 1. the ammeter's had it; 2. there's a poor connection for the parking light; and 3. the headlight bulb needs to go in straight in future. I'll get an ammeter first, before I sort the bulb contacts, so I don't have to fiddle around holding a piece of wire on the ammeter contacts. Can't say it's not interesting. Okay, maybe you can. But I'm enjoying it. Phil.
