Hi all, Given I finally have some time on my hands I am getting to some much needed boat maintenance. First job is to fix the wiring in the dash. Problem: Perfect Pass turns off whenever I start the bilge pump, blower or any other accessory, and all the gauges flicker and read higher whenever an accessory is on. Also, prior to start-up Perfect pass does not have enough power and starts and stops until the boat is running. I have read other dash upgrade posts, but I am not sure how far I should go. I have run new Positive and Ground feeds to the dash, replaced all the wiring on the breaker panel, I didn't like the piggy-back design for the breaker so i installed a Buss Bar. I have not started the gauge wiring yet. Should I remove the daisy chain for the Ignition (purple wire) to all the gauges, and the daisy chained Grounds to same? Or will the upgraded wiring to the accessories solve my problem. If yes, should I do the same to the daisy chained gauge lights (blue wire)? Not sure if I need to renew every dash wire, but if this is recommended let me know. Some of the connectors to the gauges is this large rubber 3 pronged boot (looks waterproof) that I cant get the wires out of so I will either need to splice longer lengths of wires to the existing wire, or chuck the boots and use a ring connector, Not a big issue, but if it works I am not keen to change it unless this daisy chain is the source of my problems). I am hoping the weird breaker wiring has fixed my issues (unneeded wires were going everywhere and some wires were corroded). If anyone has replaced the wires in the rubber boots, how did you do it? Connecting new Positives and Ground - what is the best way to connect the new + & - cables from the engine? Before the pugs to the dash, or run it to the dash with a plug, or leave extra wire so I can get under the dash, and should I leave the existing cables there? The Positive feed at the Engine breaker is covered in silicone, is this normal? and if so, should I replace the silicone when I hook up the new + cable? That's it for now, any ideas would be great. FYI, i am using marine wire, heat shrink and am even trying out those waterproof solder joiners. ------------- 1994 SNOB |

yes, they are very good, but I they don't answer the questions I have posted. that is, should I remove the gauge ground daisy chain, ignition gauge daisy chain, and blue light wire daisy chain to the gauges, or just add a better ground to the existing wires, as there is not much voltage usage at the gauges. I have used a Buss for the breakers, and will be upgrading the feeds as per other posts, but i am not sure whether the gauge cluster is the source of my problem. However, if others have renewed the gauge cluster wires i am interested in the results. I suspect I may need to renew connections or wires to the accessories attached to the breakers as well, if the breaker upgrade does not work given that its when I turn on the bilge etc the electrical issues start. The other questions regarding the best way to connect the new feeds, i can figure out. Maybe I should also document the work for others. ------------- 1994 SNOB |

just reviewed that post again and saw that didn't read a few pages with some little gems that answered my questions.  ------------- 1994 SNOB |

Ok, this is what I have done: 1. New Ground from engine to dash - I had some 0 gauge wire so should be plenty, 2. Ground Buss x2 installed for all dash grounds 3. buss bar install for breakers 4. 8 gauge wire upgrade to ignition breaker existing feed from engine breaker. I didn't touch the gauge daisy chain, primarily because I cant source purple and blue marine wire at 16 or lower gauge in town. I thought I would so how it performs first by just upgrading the feed to the key and if the issues still exist I will order in some colour coded wire from Amazon. I did find a number of corroded wires that I replaced, but a lot were like new. I connected it up and it fixed the flicker in all the gauges except the volt meter. Prefect pass now turns on when the key is in its 2nd position (before the upgrade it wouldn't turn on, to would just beep). With the engine off I am now getting 11.3 volts at dash there is still a voltage drop from the battery which is reading 12 volts on the multi-meter. With the engine on perfect pass is reading 13.2 volts. It was a vast improvement, all accessories work perfectly and perfect pass does not turn off when i hit an accessory. I have nearly finished the engine wire upgrades which includes: 1. new battery cables (o gauge) to engine 2. 0 gauge ground to the dash and amps 3. an additional 8 gauge feed from engine breaker to dash 4. alternator wire upgrade to 8 gauge (the biggest I could go with the room I have at the engine breaker. 5. upgrading all other feeds at the engine breaker. Hopefully I will get 12 volts at the dash with engine off, and no voltage drop from the alternator, will finish today hopefully and post results. However, the upgrades so far have been well worth it. ------------- 1994 SNOB |

I agree. This one should go in the FAQ's. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

final outcome: Finished all the engine wire feed upgrades and cleaned up the wiring. Now I am getting a .2 voltage drop to the dash, with engine not running and .5 drop when boat is running. I could possibly upgrade the Alternator wire that might help, but I am happy with the results. FYI, there is enough thread on the engine breaker to add additional feeds and went with 8 gauge hot feed, The biggest difference was re-wiring the Breakers to Buss Bars, upgrading the ignition feed wire gauge and the new ground and positive feeds. ------------- 1994 SNOB |
