FLU419 SEE HMMH HME Owners group

BA7s bulbs are very popular in Europe. However, I was told that if I use lower wattage bulbs that they didn't put out much light and the plastic cover really diminished the results. Mercedes warned me that the higher wattage bulbs tended to melt the plastic due to the heat. I'll try the LED bulbs which should be bright enough and not put out much heat.

Liking how Mercedes is "someone" you can actually contact and talk to:

- My guess is that most manufacturers liklely can't even be reached for any kind of discussion

Did you actually talk with a human contact?

Yes, I contacted Mercedes in Germany. I got transferred 4 - 5 times before I got to someone that had any technical information. I initially indicated that I was an investor. That got me by the automatic no help. That process is my secret weapon when you need help with any public traded company. Once within that group, I requested someone in a customer service / technical support position familiar with Unimogs or trucks that were 24 VDC. The guy was very friendly and helpful and his English was better than mine.

Excellent tactical move, glcaines!

I'm adding that to my kit:

- Thanks, Brother!!

Speaking of LEDs.

In the past couple of days I've been working on getting the lighting functional on the FLUs. One had a dim work light, turned out to be resistance in the head/work light switch. But the first one I bought had nothing...other than power to the work lights.

Disgusting, really, that a pair of $18 lights didn't quite make it to 10 years. Oh well, I have a stash of replacements so that was an easy fix.

Last, and least, is the HMMH. No power even to the fuses for the forward lighting. That might become fun to figure out. Started with that one and spent some time on it before deciding to reward myself by fixing the easy ones first.

It helps, FLU farm, right?!

Get your spirits up before you enter what may become Darkness (you know, so-to-speak).

Where is the brake light diode mounted? Mine was simply hanging on the end of the wire on the front wiring harness and not mounted. I couldn't find it in the TMs.
EDIT: Found it.

 

[glcaines]

I'm in the middle of replacing the front wiring harness on my FLU419 due to severe mouse damage. I have it installed, but some things don't work anymore. I'm slowly getting it sorted out with about 98% functionality. However, one of the things that has me puzzled is the air compressor. The air compressor worked and charged the tanks fine prior to removal of the old wiring harness and installation of the new harness. Now, my air compressor never engages. As far as I can tell, there are no electrical connections that would impact the air compressor from being energized. I can't find anything in the TMs, the Student Handbook, etc. There is obviously something I'm overlooking.

 

[The FLU farm]

Hmm. The compressor is direct driven and always runs when the engine is. Or should. Either way, nothing you did with the wiring could impact the function of the compressor.

I'd guess that the compressor does pump air, but it doesn't get to the tanks anymore. Is the regulator flowing air?

 

[glcaines]

I know the compressor is supposed to run all the time, but it was charging the tanks until I swapped the wiring harness with a new one. I guess it's possible there was a failure somewhere in the pneumatic system that coincided with my work. I don't hear any mechanical noise from the compressor, there are no noises from air leaks or air discharges, but zero air is getting to the tanks. I'm going to disconnect the output line from the compressor and see what I get. I'm still working on swapping the wiring harness, but I'm about 99% done with that. Swapping that harness is a real bear. The new harness has all of the connectors labeled, but the labels aren't on the schematic. Some of the wires on the new harness have wire numbers from the schematic, but not very many. The wiring harness I got from EI is very well made, I just wish I had access to information on the numbered connectors. I contacted the vendor that manufactured the replacement wiring harness, but they told me everyone on that project is now retired and they dumped all of their documentation years ago.

That seems short-sighted; almost criminal.

But, yeah, business management doesn't always much give a damn about history.
