Hi Rich, Yea I've been studying the electrical system for a couple of weeks. I usually research till I find my answers but I'm trying to save some time. This current shunt was already wired in and I did not know what it was or waht it was called (well I thought it could be a simple 2-post terminal but, that didn't make sense given the rest of the wiring scenario and that ribbed plate) so I couldn't research it. What I intend, is to clean up the sloppy wiring while hooking it all back up again after the re-power. Electrical systems are really quite simple and very much like a plumbing system and i have done quite a bit of wiring on various thigs, cars, motorcycles, my house and my previous boat.
My boat is very simple actually. It is still pretty much wired the way it was when it was built. just new wire went in to replace fauly wire and the faulty wire was left in place and the new wiring was ran hap hazardly. I've got a pretty good grasp on it. I was just trying to see if I could neaten up a few more things. Adding a grounding block is pretty simple and I could simply run another heavy wire to the block I was just wondering if could run the positive and the grounding block in series or in line. (I'm sure my terminology is off a bit...LOL) I just feel there really only needs to be one wire to the engine block and all the other grounds can terminate on the grounding block. Same is true of the positive block. I was thinking I could run the positive wire from the switch to the positive block and then run a single wire the the starter solenoid instead of running the main battery positive to the solenoid and then another wire back to the positive terminal block. The PO just kept piling wire on top of wires onto the block, the battery and any other, apparently, easy location and I'm just trying to avoid that scnario again. I've read up on the current shunt and understand it now and I guess running anything of of it is probably not good practice so I'm back to my original plan with that and simply reinstall it the way it was. I've started a wiring diagram and here is a link to it; http://sdrv.ms/OTH0dc you can scroll around and see loads of pics O took for reference. So at this point I'm just interested in putting it back together nice and clean and get sailing. I appreciate the offer and I may just take you up on it.

It is difficult to determine exactly what you are trying to do. If you are having problems that you feel may be the result of incorrect wiring, I suggest you get a professional to look at it with you and give you some direction. If you want to do it on your own, I strongly suggest getting a copy of Nigel Calder's Boatowner's Mechanical and Electrical Manual: How to Maintain, Repair, and Improve Your Boat's Essential Systems. Every wire on a boat has a purpose and an appropriate place to connect to form the system. It's very hard for anyone on this list to determine how you should make changes to your boat's wiring without knowing what you have to begin with. If you would like to, I suggest you make a drawing of the system as it exists, scan or photograph it and email it to me off line and I'll be happy to have a look at it and then discuss it with you.

I bought 2 terminal blocks to use for positive and ground connections in the engine compartment. Should I run the positive and negative battery wires to those terminals and then to where they connect to the starter solenoid and block? Or, should I run those wires direct and then jump back to the terminal blocks?

The ammeter measures the voltage drop across the shunt and converts that to amps flowing through it (amps = volts/resistance). regards, Graham Collins [email protected] wrote: > One side went to the starter solenoid and the other to the alternator. > Then each side went to the ammeter... > What is its function? > > ---------- Original Message ---------- > From: Steve Thomas <[email protected]> > To: <[email protected]> > Subject: Re: Stus-List Electrical Block > Date: Tue, 24 Jul 2012 16:01:31 -0400 > > Looks like it might be a current shunt for an ammeter. > -----Original Message----- > *From:* [email protected] > [mailto:[email protected]]*On Behalf Of *Joel Aronson > *Sent:* Tuesday, July 24, 2012 3:53 PM > *To:* [email protected] > *Subject:* Re: Stus-List Electrical Block > > Danny, > > Almost looks like a high amp fuse, but I think it is just a block. > Might want to move the bilge pump hose off that wire! > BTW, nice stuffing box, but I don't know the answer to the grease > question. > Joel > > On Tue, Jul 24, 2012 at 3:45 PM, [email protected] > <mailto:[email protected]> <[email protected] > <mailto:[email protected]>> wrote: > > > Another question.... > > Is this Positive block, just that a positive block or is it > something more? > > <iframe > src="https://skydrive.live.com/embed?cid=CCBEFDFB44F8315F&resid=CCBEFDFB44F8 315F%21309&authkey=ABkwZnrwurnZ08s > <https://skydrive.live.com/embed?cid=CCBEFDFB44F8315F&resid=CCBEFDFB44F8315F %21309&authkey=ABkwZnrwurnZ08s>" > width="320" height="180" frameborder="0" scrolling="no"></iframe> > > or this link if that doesn't work... > > http://sdrv.ms/PebU41 > > Danny > > > _______________________________________________ > This List is provided by the C&C Photo Album > http://www.cncphotoalbum.com > [email protected] <mailto:[email protected]> > > > > -- > Joel > 301 541 8551 > > > _______________________________________________ > This List is provided by the C&C Photo Album > http://www.cncphotoalbum.com > [email protected] -- Graham Collins Secret Plans C&C 35-III #11 _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com [email protected] _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com [email protected] _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com [email protected] _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com [email protected]
