Yup, I used the 50 amp breaker. There was just enough thread on the stud to catch a second ring terminal. I can grab a pic of that side when I get a chance.

With all the wiring problems these boats have this post deserves to be kept bumped up. How did you run the additional positive? From the 50 Amp breaker at the engine? |

I stuck mine to the flat part of the dash just above that spot with double sided tape, and doubled the wires on each screw so that I could have a ground on one side. That way you can flip the dash without having to unhook things.

When I lift up my dash pod, there is this little shelf like area that is part of the hard fiberglass behind the pod. The bus can sit in there as one place to put it:

Adding a couple pics of proposed positive side upgrade:
Here a couple pics of the current positive daisy chained positive going to the inputs of all the breaker switches: Some of the black wires you see are grounds running past and some go to those little led lights that illuminate when the breakers are on. Those little indicator lights just use black wire for some reason. |

Keith's video will probably show where, I've never done one of those. Doesn't sound much different though, red to the battery wire at the key, purple to the switched terminal at the key and black to the ground buss. I'm guessing it's not as temperamental about the voltage as the PP.

Don, this is just the Precision Star (JUST the GPS speedo) ... it's installation says "Red" to continuous 12v, "Purple" to a switched 12v source ... "[m]ost boats will have a Purple wire at the ignition termini and at the back of your gauges if they are powered when the key is turned on" and the "Black" to ground. Please clarify. Oh yes, sorry, Enoch wire???

PP goes on the purple wire, run the ground to the buss, grey goes to the tach. Be sure to use Enoch wire so that you can still flip the dash and work on things.

Yup ... that is what I thought I understood ... just looking for clarification ... Don, can't wait to show you my stereo solution ... busy, busy, but I will get pics up soon!!! Leaving on SN vacation on Wed. morning!!!
Last electrical question, I need to wire up my PP StarGazer ... just want to clarify that I am put the leads on the right posts on the ignition switch. The ignition: The leads off the PP unit: IMG]uploads/12767/PP_Leads.jpg[/IMG] Just to be clear ... I am going to connect the purple lead to the purple/red on ACC (12 o'clock) as shown, and the red lead to the BAT all red (at the 6 o'clock) ... the PP speedo requires a "continuous 12V source." Thanks, as I am trying to get this done today! Next, Gore shaft packing and then we are good to go (I HOPE)! |

In an ideal world the block is just a big ground buss.

Yup, the loop is there ... Thank you very much ... once I had completed the work I, of course, found the ground at the back ... it was like "Oh S****" ... as I am trying to improve things, not muck them up. Thanks!

Yup, I agree. Your choice of dash-to-engine ground should work great.
One note, when you use a "dual" bus, as a single (ground only) bus, you have to remember to make a loop to connect the two sides to make it all one. It looks like you did that, but it's a little tough to tell for sure with the picture. |

Your new ground is just fine; that is where I put mine.

New "electrician" taking a shot at this upgrade. I have added the bus, cleaned up some wiring under the dash with the original ground chain, but am now second-guesing my choice of where I ran the new ground on the engine. After looking earnestly (I have Pro Tec) I wired to the battery ground on the engine block up front and THEN found what I believe is the original ground on the back of the engine. Do I need to run my new 10 AWG back to the original ground or am I good the way I have it? Thanks in advance!

I think Brian pretty well covered the not right part, I'll agree with the sounds like it was added. I haven't run into resistors or anything like that on mine, but there are a lot of wires and I haven't messed with all of the yet. I would strech it out and see where it will reach, make sure that everything that it could reach is working. Once you know that then you can use it or remove it. They key is usually a good place to get switched power so there is a good chance it was for something that isn't there anymore.

Don, What does not sound right? There is a factory installed black wire disconected from over the years....probably by acident. I am trying to get information on where it connects. As with the small resistor. I will start a new thread in Maintance. Thx

Whatever you do, shrink and seal everything. Every time I've had an issue it has started or gotten worse because the boat got too wet. It seems like no mater what at least once a year mine gets caught out in the rain somewhere that I can't keep it dry like I do when I'm at home.

My volt meter reads low, This causes my gauges to read high. I know its a problem but I know the system charges properly so I haven't messed with it because I know it's a bad ground. I really like that Idea Brian. Quick simple effective fix. Probably on my to do list now. I was going to re run the grounds but that will be much easier. I also found a voltage drop over my ignition switch and my ignition breaker. Those have since been fixed. A few minutes with a ohm meter told me the voltage story and the ground story. CC sure did make it easy to get a good ground with the battery right beside you under the dash in the 2001 hulls!

Neither of those sound right, blacks are grounds. Do all the lights work for all the gauges?

With my dash pod out of the boat I replaced 2 breakers and checked all the wires and replaced the speedo bulbs. I have 2 disconected wires???
There is one black wire running from the ignition switch over to the area of the breakers that is disconected. I have no idea where it connects. The black wire is connected to the ignition terminal with 2 purple wires and 1 pink? I also hace a very small resistor connected to the ignition breaker terminal that is not connected to anything on the other end? |

Thanks.......Tom

I got the ground bus bar at West Marine. There is a big one near me that has a good selection of all that stuff.
Keep in mind, the one I used is actually a two circuit one. I made it all into one circuit with that one wire that loops back onto it. I chose that particular model, because it's low profile. Some of the other ones had studs that were really tall. |

It's the OCD I guess I did it partially for the pictures too.
The cargo liner is nice, cause it keeps everything contained. Black isn't necessarily the best choice when working in the afternoon sun though. |

How do you keep track of anything in all that mess with everything laying around. Lol. I just throw it all in my 5gal bucket and dump it out where I need it, saves time, I bet you spent more time organizing everything than you did making wire connections.

The ratcheting crimper really comes in handy. If you close it one "click" on to your terminal, it will just hold it in place automatically. Then, you can more easily insert your stripped wire end into the opening. Well worth the money over the cheapo one I was using before. The multi stack terminals are very useful. You take a length or wire, and attach these to one end, and a ring terminal to the other. You put the ring side on your bus bar. Then, the multi stack connection can connect to your gauge, and re-connect the original daisy chain on top, to keep it in tact. |
