1985 300CD Electrical Fuse Problems Circuit 8
I have an issue with my daily driver. It is starting to get cold here in New England and would like to solve as quickly as possible. I am pretty handy mechanically but eletrical problem solving is not my forte so hopefully someone else can suggest some things to look at.

1975 240 D Electrical Power For Radio
I do not have any power to the electrical supply to the radio. Just bought the replacement fuse set from Kent and have cleaned all terminals and replaced every fuse. On the fuse box lid there is not an indicated fuse for the radio. So,,maybe I am not looking in the right place. Where is the fuse for the radio supply?
Thanks,

1984 300D Injectors Replaced, still rough
I just purchased some rebuilt injectors (the Monarchs on this site) and replaced them over the weekend. I did a valve adjustment while i was at it. Put everything back together and she started up after some cranking, but it didn't fix the very rough running of the engine. I'm happy to have the new injectors in there as I was due for them, but now I have to run down the problem. Think it could be the injector pump? Seems like a cylinder may not be getting fuel, or perhaps very little fuel. How can I check to see if the injector pump is working properly (or any other ideas)?

81 240D new voltage regulator squealing
Since my 240D's alternator clearly wasn't charging anymore, I figured I first better replace the voltage regulator. The old regulator was clearly shot, and I got the new one in. Now the alternator is charging fine, but it is also making an intermittent loud squealing noise - especially when accelerating. Any chance this noise will go away or diminish as the new brushes "break in", or is it time for a new alternator?

I had to remove the Sender Unit - Guage today and noticed that three of the five bolts were already missing. The other two are extremely rusted. The bolt part is crimpted to the indside of the fuel tank. Can this part be replaced or is a new fuel tank needed?
