Both my low beams are out on my '73 bus which is parked at the moment, high beams are fine. It seems there is one fuse for each side, left and right. Could both LB fuses have failed together, or am I barking up the wrong tree? The only reason I haven't checked the fuse box myself is that I just noticed it (at night) while moving the bus under cover.

There's a thingamabob next to the signal relay also.
Mine went on me once. It was full of water that leaked from windshield

If your fuses check out ok, cycle the high beam switch several times. It is possible that the high/low beam switching relay has failed. This might be the thingamabob in the relay panel that Brent is referring too...

OK, great advice. The van was outside, but with a high quality cover. Even so, moisture can collect I suppose. I'll check it out tomorrow. Here's a pic from the Samba of the backside of a '73 bus fuse box. Brent are you talking about one of those relay like things?  |

It's in the dictionary. Who would have thunk!
thing·a·ma·bob or thing·u·ma·bob
n. Informal
A thingamajig
--------------------------------------------------------------------------------
[Alteration of thingumbob : obsolete thingum (from thing) + bob.]
thing•a•ma•jig or thing•u•ma•jig
a thing for which the speaker does not know or has forgotten the name.

OK, I figured it out. Brent was right. If you're sitting in the driver's seat there are 3 relay thingamabobs on the bottom of the fuse box. A big one on the left (don't know what that does yet,) then the middle big one that controls the low beams, and a tiny one on the right which is the door buzzer (mine still works!) I couldn't unplug the low beam relay, and not wanting to force it I wiggled it and discovered there must be a dirty contact, perhaps some condensation in there. A few wiggles later the low beams came on intermittently. A few more wiggles to get it working and then I let the bus run with the headlights on and the heater to hopefully get any moisture out. I let it run for a while until everything was fully warmed up and it seems alright now. You have to run the electrics to keep them current, pun intended. Thanks for the input...  |

Good info Tom. Glad to hear you got it dialled. I think we should officially change the name to thingamabrents |

I believe the first one is your signal whatchamacallit Thanks guys, Brent, OK signals is it? That reminds me of that problem most bay owners will eventually experience where your turn signals won't work until you give the emergency flasher knob a good tap. |

I guess that is why I have seen more than one of these switches wrapped with zip tie behind the dash? |

OK Brent, signal solenoid then, like a starter solenoid that doesn't carry the full current. And Don, yes, maybe someone was trying to stop it from moving about. Although most people never use them, the flasher knobs do wear out. I believe they share the signal solenoid and that's why the turn indicators stop working too. I remember my first Nanaimo show at Rutherford Mall (2006?) I had just bought my '74 bus and the turn signals were acting up on the way up to the show, which meant no lane changing. One anonymous bus owner looked at the van and said, "oh, no problem, it's the flashers," jiggled it and they came back on, the fix lasted long enough to get it replaced.
