3607 Bridge Rewire
Posted: October 8th, 2020, 8:29 pm
Well, partial rewire. While troubleshooting a spotlight issue, I decided to finally tackle some of this and clean up some wiring. I thought I had a "before" picture, but I can't find it. Just imagine a bit of a rat's nest of wire.
First, I had to make a mounting board. Under the helm there really is no where to mount anything except a small 3/4" x 3/4" blocking at the top and a 2.5" band at the bottom. So I had some old marine teak plywood and made a mounting board:
Getting it in behind all the existing wiring was a chore, but I got it in. You can see the old terminal strips which are just push-on connectors. That was the standard back then. They were screwed into the top but I had to remove them to mount the board. They get corroded after a while and develop some resistance so you have to periodically clean them off if you want them to work correctly. You can also see the tach syncronizer hanging. It was also mounted up near the top but since there wasn't a big enough surface it was just kind of hanging diagonally.
Here are the new terminal blocks with some of the wiring going in. Most of the stuff has their own fuses inline. I had to add a couple more. I had thought about putting in a fuse block like I did in the lower station (different thread for that) but I wanted it to be accessible without having to unscrew a panel. This will be a huge upgrade over the push-on terminal blocks.
In this process I found out that the spotlight was never actually feeding from the spotlight breaker provided on the main panel. The breaker was there and all the wiring provided by Carver, but whoever installed the spotlight just tapped into the bridge feed (there's a 25A breaker and feed for the bridge and a different one for the lower station). I was able to wire it in correctly so now that's on it's own breaker like it should be.
