Well, mine received 3 brand spanking new Halogen headlights tonight!
And I learned something... headlights burn out at the speed of light!
One was already blown on the high beam, and I had forgotten I needed to replace it.
The other two were mechanical error... or rather operator stupidity...
I don't fully understand it, and will be studying the schematics to see why it happened.
I forgot to hook up the 12v tap on the batteries when I was working on them this fall. I had left the headlight switch on the last time
I shut off the bus, and when I flipped the master switch on tonight, I saw one go. Bright 24v flash!
That wasn't good enough. Stupid me had to hit the dimmer switch and take out one of the high beams, too!
Again, I don't understand why not having the 12v tap would cause this. Somehow it must be providing a ground for the 24v side of the
series connected bulbs. Will have to see if I can figure this one out so I can figure out a way to prevent it from happening again.
