Headlights won't go off

[Greg Young]

I'm pretty sure the failure is in the high beam switch. However, to get to it requires tearing apart the floorboard around it, a task which I have neither the time nor energy to do right now. We are packing for our annual trek to Burning Man, leaving on Monday. So I installed a cutoff switch for the line going to the headlight relays (used a 50A switch and 10ga wire to minimize heat and loss) and we can roll that way. However, it's certainly something I need to fix. Even if it turns out to be wiring on the way to the high beam switch, I'll need to do a major tear down, so either way that's in my future. But not now.

One of the two blowers that exhaust hot air from the genny compartment was broken - the blower wheel was torn to pieces. It took me
quite some time to locate a supplier, then they sent the wrong wheel. Then they failed to ship when they said they would, so I missed the window to install it while at home. So now I've asked them to ship it to a stop on the way next week, hoping that it will be the right one and on time. If not, we probably won't be able to use the genny during the day for long as 110 degree temperature and 40MPH dust storms really overwhelm its cooling system.

And I had to replace the high temp sensor switch on the 8V92. It had failed and the fan wasn't coming on, as well as having the engine alarm triggered. Dan at Parliament was very helpful getting the part. While I was at it I replaced the water temp guage sensor. Got a nice coating of coolant all over me in the process (dummy standing in front of the thermostat as I removed the switch).

So everything else seems to be OK! I really love working on this... but
sometimes it frustrates me because my knowledge is so spotty. I don't know what I'd do without the forum. Probably would never have bought it in the first place!

Thanks again and hope to see some another Bluebird or two on the playa!

Have you had any luck yet on the headlight problem?
