It has been quite a while since I updated this thread. I have been busy working and such, but have made some good progress on the car.
Rich76_911s pics of the rust on his car inspired me to take the front end of the car apart to inspect and give a proper cleaning. It is amazing how much dirt gets caught in those fenders. Thankfully, after a good power washing, there wasn't any rust in there.
But, just because fate seems to want me to replace
everything on this car, I noticed that the washer fluid reservoir fill hose had been rubbing against the tire and had a several inch section that was paper thin. And the tubing to the fuel vapor catcher thing was rotted with the smaller tube being completely severed (that explains the occasional smell of gas near the front fender). Luckily it was easy to pull it all apart, get some fresh tubing and reinstall with some new stainless steel hose clamps. BTW, that washer reservoir is the damn biggest one I have even seen, they must have lots of dirt roads in Germany.
I then got back to my main task of rewiring the car. I got out the trusty multimeter and verified all of the lines in every loom as well as the ground points. I had already pulled out the fuse panel for some cleanup and fresh paint. So, I took on the task of re hooking up all of the wiring per the Bentley schematics. That took several days. While I was at it, I replaced all of the fuses and relays. The PO seems to have moved a few wires around, and a couple others were simply not hooked up and tucked behind the panel. I'm glad to say that everything is working correctly now. I also picked up the headlight relay from our host and put that in for good measure.
The only change I made was running a new 14ga to the cig lighter and giving it a dedicated 15a fuse. Seems that the old line in the loom was cut and a new 20ga wire put in it's place with a direct connection to the battery (no fuse). It was just begging for a meltdown.
I threw in new bulbs all around since I was in there.
My CEET tubing came in, so I was able to also tackle the fresh air blower system. I broke open all the distributor pieces and game them a good soap and water cleaning. They can get pretty nasty in there. I then cut up the tubing and strapped it all together with some stainless steel clamps. I also pulled the control unit and gave it a good cleaning and adjusted the contact points. Seems that it previously wasn't able to reach the fastest speed. This is what it looks like now:
I'm still having a great time!
