Wiring Harness Upgrade
Here's another one. This is June 2010. For a 1988 boat!!!
Warn ya? Ha! Thanks to Bob for his report.http://c34.org/bbs/index.php/topic,5722.0.html
Ron has said, over and over again, that there are STILL boats out there who haven't done it. http://c34.org/bbs/index.php/topic,3716.msg21837.html#msg21837Even IF you have a voltmeter, you could still have the OLD stupid connectors.What's your boat worth to you?Here's another one, September 2010, 1987 boat: http://c34.org/bbs/index.php/topic,5861.0.html
And another followup: http://c34.org/bbs/index.php/topic,5866.0.html
Thanks, Todd & Len.
From one of the many wiring harness links:
Of the many wiring harness references in the Knowledgebase this one is noted: DO IT NOW
On a repeated
basis, both here and in my Secretary's Reports in Mainsheet, I have been noting that owners of older boats NEED
to read the material. And then ACT
I also believe at least an understanding of, and better yet an ability to repair, boat systems is essential to safety
. I didn't know any of this stuff when we bought our boat, but I read the stuff
, and I bought the tools, started working on things, skinned many knuckles and feel that I have a responsibility to me, my family and my guests to get them out and back safely. I know we all do, and some have differening abilities and interests. But the information availble to us on this website should make it no excuse for anyone to NOT repair those things that are obvious and begin to learn about the others. In the worst case, some $$ can be saved on yard bills by at least knowing more about the complicated machinery that our hulls surround. From the May 1997 Tech Notes (by Ron Hill): Engine Harness Upgrade
– Do It NOW! Our November ‘96 Mainsheet article on electrical systems really stirred up some
interest. Hank, Duane, and I have all received a number of requests for our electrical schematics. But, I still am hearing from people who have not made the engine harness upgrade. So much has been written and talked about that modification, I surely hope that nobody really wants all of the power from the alternator going direct to the key switch in the rear of the boat, then coming back to the battery selector switch, and finally (the few amps left) to the
A few years ago Bill Beck, “Prosit”, hull #1186, had just anchored and took
their dog ashore in the dinghy. His wife, Dot, was on the boat by herself when all of a sudden the engine started itself. She tried to shut the engine off but it kept restarting. Dot dove overboard to get off that “crazy” boat. One of the harness connectors had shorted out keeping the starter engaged.
Fortunately the starter burned out before it started a fire. Bill had NOT modified any of his C-34 electrical components and had NOT upgraded the harness.
In the spring of 1991, I installed my high dual output alternator (each output
goes to a battery bank bypassing the battery selector switch). I had the engine
harness upgrade but had not installed it. I did, however, take the harness connector at the engine apart, inspected the terminals, and disconnected the old alternator lead to that connector. Everything looked good so I rewrapped and wire tied the connector. I thought the upgrade installation could wait as only low amperage would be passing through the connector. The next spring I added Bob Bierly’s (C’Mon Wind, hull 913) VHF radio modification in the cockpit (Mainsheet article May 1995). Had to take out the engine instrument panel anyway so decided to do the half of the engine harness upgrade at that end. Maybe a month later I got around to the other half of the modification at the engine. To my surprise, when I took the connector apart, the side with the male pins crumbled in my hand.
If you haven’t made the engine harness upgrade, you may want to reconsider.
