Another update here. I'm not posting pictures of every wire I replace, but the renewal of the electrics inside is almost done, while the weather here is still bad, no oldtimer driving weather

One of the tasks I did was restoring the fuse holder, because ist looked like this:



Very rusty, bad contacts, some non fitting fuses violently pressed in by the preowner I had very strange electric effects because of contact resistances and loose connections - like direction lights failing from time to time, contacts getting hot when I turned on the lights etc.

I also had much trouble while I was trying to retrofit hazard warning lights (legally required here, I'll post this story later), because I needed 12V for the relay. My multimeter proofed there were 12V on the line, but the relay strangely didn't work. After some troubleshooting I found out that the reason was another contact resistance As soon as the line had some electrical load, the voltage dropped down to almost zero

So I removed the fuseholder, removed the fuses and began cleaning all the contacts and all of the small metal plates. First mechanically...:


...and last chemically by using Pelox RE:


Pelox RE is just phosphoric acid, it etches all the remaining rust particles away and passivizes all metal surfaces.

After cleaning it again and drying I replaced all the old fuses by new ones and also all the screws were replaced by new ones of stainless steel:



...I know its 10A fuses and not 7,5 like original, but these are the closest ones you can get here in Germany with this mechanical size.

Back in business...:


Direction lights now worked 10 times in a row without failing, and no contact is getting hot anymore, wow

More stuff will follow shortly
