I think I could have potential electrical problems if I didn't discover these items...
1-positive battery connection...is there anyway to correct this other than replacing the positive battery cable...check out the pics....
2-also the wires to the rear fuse box (main wiring harness to the rear fuse box)... have or had corrosion (now removed)....but a break in one of the wires....which electrical tape should fix....
3-need to replace some conduit as it also is eaten away....
4-have no clue what I believe is a water drain from the windshield cowl area that dumps right into the battery area....where all this takes place....think I will somehow extend this....so it will dump out below the frame....
Just going to take longer than expected to get back on the road.... [emoji16] [emoji16]

Pic #1..battery cable dilemma...any ideas on how to fix...other than replacing the positive battery cable???
Pic $2...corrosion under electrical tape...I think I could have potential electrical problems if I didn't discover these items...

Pic #4...wires cleaned as best as can be...
Pic #5...have no clue why a water drain was placed there to drain right into the battery compartment area...
Pic #6...even some of the conduit fell apart..

You can get a replacement battery terminal connector. The issue with this is that the corrosion you see more than likely travels further up the cable, under the jacket. Maybe replace the connector, buy a new cable and replace it whenever you pull the plenum again.. The rest is easy fixes. Neutralize and clean up the corrosion, replace wire loom. The water is coming from the rubber drain tube from the windshield cowl area, re-route it away from the wires if you can..

What he said!

I would use a longer drain tube or a connector and an added piece to get it completely past that area.
That damage on the smaller wires also appears to be more battery acid induced than water drainage or accumulation causes.
That positive cable is trouble with a capital T!
Great that you went on your exploration!!!

Better off replacing all the suspect cables and move on. Replacing the positive starter cable will require pulling the plenum and coil tray.

Appreciate the replies everyone....looking for the correct positive battery cable.....in the meantime I found the battery cable washer that is used in the positive cables of our Z's.....it is part #11501869 and I assume that this is the size as it was posted with the part #......M8X15X.85 and that was used as mentioned for VIN J......did a search and nowhere to be found....

[Roadster]

So I did a partial cleanup on the washer and even went further inside the cover to remove any signs of battery acid powder in there....there was some...but the further I went...the less that there was....I ordered a battery cable spacer that I'm hoping will fit in there just right and provide full contact when the cable is attached....what i would like to do....is find that washer and cut the cover open and just replace the washer and then reseal the cover....as I never had any problems starting the engine at all....I really don't feel like doing another plenum pull if I don't have to...but if it has to be done....as I have enough going on as it is....lol....pics below after preliminary cleaning of the disintegrating washer so far...the metal that is still there is solid....so with the spacer added....it might work just fine....

[Roadster]

Did some research and found that the battery cable washer is still available from GM....although a little pricey IMO....I ordered a couple of them from the dealer..I also found another set of cables for the LT5 from one of our members on the forum....so if my experiment doesn't work....I can always change out the positive cable....here is the part #11501869 for anyone interested....also found out that the part number for the positive battery cable is #12073841 (which we know is no longer available)...this part number was replaced by #15320758 as per the dealer parts man and is also no longer available....but may help in future searches for buying purposes....[emoji16]20201022_005428.jpg
