Thought I'd start a new thread for this.
You've probably all seen my Shadow for sale. Decided to try and sort out these electrical issues for myself. I have seen some areas already where the engine harness casing is cracked and exposed, potentially groundig to the chassis. Given this, rather than chasing bullshit all over, and strugglibg to get at things, I'm starting this out by pulling the whole harness, cleaning it all up, repairing all issues and then putting it back in.
Wish I had some amazing progress to report but the wife got sick and I had to pull double duty this weekend. I did manage to sneak out for 30 minutes though and pull a few plugs with two jobs, an hour commute and a 9 month old, I have a feeling the only way to get this done will be 30 minutes here and there.
