YouTube Video About The Common Ground On My Boat, on Feb 01, 2018 asked:

Hi Jeff, during one of your videos, you commented on the critical need for a chassis grounding cable, one size smaller than the supply cable. Where should this ground cable terminate? The engine, thru-hulls or somewhere else? Thanks so much for taking the time to produce these videos; they’re a great source of information and safety and they instill the need for professional expertise and at times installation, when working with marine electrical systems. Thanks again, Rick

Crimp vs Solder, on Jan 02, 2018 asked:

I am rewiring my Ranger 23. When I tried to replace an instrument I found that the wiring was a tangle of wires. I have watched all your videos on marine wiring and you always crimp connections. Is there a reason you do not solder them? - Richard

Automatic Combiner Relay or Voltage Sense Relay, on Dec 01, 2016 asked:

Hi Jeff, I met you the other day while you were performing an Electrical Audit on a friend’s boat. You mentioned a product that allows you to direct excess power from one battery to another when charging. What is this called and how hard is it to install. – Rob

Reverse Polarity Light and a Portable Generator, on Oct 05, 2016 asked:

I'm up here in Prideaux Harbour and tried to charge my batteries and can’t. I have a Yamaha 2000 watt generator connected to the shore power - it worked with the old charger. However when the generator is connected, the 120 volt reverse polarity lite comes on (always has). Is the new charger sensitive to this, thus causing the charger to cut out? Is there a fix for this? - Dieter

Should I install an external fan for my inverter/charger? - Mike, on Apr 04, 2016 asked:

I would like to install a fan in the area that I have installed the inverter. I have cut two large holes to help with circulation but I still don't think there is enough ventilation. Is it possible to add a fan that operates automatically each time the inverter turns on?

Solar FAQ, Monocrystalline vs. Polycrystalline – Tom, on Sep 01, 2015 asked:

I have enjoyed your Pacific Yachting Tech Talk articles as they are not condescending or preachy. I have also been reading about the Gioco panels you distribute. My interest is twofold. I would like the benefit of solar charging while cruising and secondly, I would like to be more independent of shore power in our Marina where I have recently experienced "issues" from being connected to its AC shore power. We have owned our current boat for a year and replaced our zincs this April when they were 8 months old and half gone. I recently dove under the boat while out at anchor and was shocked to find the prop and shaft zincs were 95% gone after 90 days! We have a Beneteau 36 center cockpit with a full bimini that I think would make a great location for one or two of the flexible monocrystalline or polycrystalline panels and an MPPT regulator. I do not quite understand the distinction between the two types. If one panel was used now, can a similar sized second panel be added in parallel at a later date? If so, is an MPPT regulator available for the demands of two such panels? The distance from Bimini to batteries is about 10 feet; what gauge wire would be required?

15A Shore Power Tripping Breaker - Andy, on Aug 14, 2015 asked:

I have a 2003, Beneteau 361 at Burrard Marina and there is only 15A service. I only have my battery charger on and it still trips the dock breaker. Do you have any suggestions?

Converting a European 220V Boat to 110V – Nick, on Jul 31, 2015 asked:

In your many articles – have you ever written about converting a European boat, in this case an Elan 434, from 200 volts to 110 volts? If not, briefly what would be your best/simplest/cheapest solution?

Contact Cleaner and Corrosion Inhibitor – Syd, on Feb 04, 2015 asked:

What product(s) do you recommend to ensure a great electrical contact and make those connections corrosion free? I am looking at battery connections, light bulb bases (like the ones you will find in trailer lights) and wire crimps. I have come across dielectric grease, Lanocote, Noalox, Penetrox, anti-corrosive zinc paste and something with silver particles suspended in a kind of grease.

AC & DC System Upgrade – John & Jenny, on Jan 21, 2015 asked:

I enjoy your articles in Pacific Yachting each month and also the information on your website. I own a 33’ sailboat and am looking at updating the AC and DC systems as they have evolved. The DC in particular has outgrown the original architecture. 1. Should I replace the 1, 2, ALL, OFF battery switch to incorporate an automatic charging relay (ACR)? I am starting with a plan to test the current switch to see if there is any reason to replace it. E.g. the contacts still as good as new! I have a suspicion that there is a downside to an ACR, perhaps if one battery bank gets drained, but I am finding it difficult to find a clear explanation of the pros and cons. To me I seldom run in ALL mode and switching batteries is second nature. However, I am hoping my daughter and family will start to use the boat and they don’t have that background. 2. Should I install a galvanic isolator and/or an ELCI AC breaker? My sense from Blue Seas who do not market the former, is that the ELCI provides similar protection and new protection. I have been unable to verify how true this is. I am assuming that the permanent battery charger (Xantrex) may well provide a hidden interconnection between the AC and DC systems.
