Having trouble keeping power to instruments ( oil,temp,tach,temp,turn signals,speedo,fuel ). All seem to be #12 fuse position. Changed fuse, same result. I can play around with it and get it working, but only for a short time. Can my luck be that bad that the fuse box, of all things, took a dump?
Anyone ever have this type of problem?

Look at the backside of the fuse block(thing fuses go in). The different wires/circuits are screwed to the back... you will see. Sounds like maybe the screw is loose.

you are cleaning the clips, and putting in new copper with ceramic body fuses right?

I soaked my fuse block from my 300d in a tub of vinegar for two days... easier said than done

Would removing the 2 screws on inside of box ( front) the best way to look under fuses? Removing battery cable first.
Never did more than change fuses before this.

Get rid of the aluminum type fuses. You can get the new copper ones, a whole set, for maybe $20.

Some might look good, but it doesn't mean they are good. If they're pitted, etc., they could be building up resistance, and putting extra strain on other stuff. I doubt this will fix your problem, but it's something you should do anyways.

Good luck.
