How Many Battery Connections are Acceptable?, on Mar 29, 2018 asked:

I’ve recently watched some of your You Tube electrical videos and realize I have some no-no’s at my battery terminals. Is it acceptable to have more than one cable ‘stacked’ on each other at the terminal? For example, a starter cable, bus cable and battery charger cable? If not, what is the proper protocol? How do you determine the size of the cable going from a terminal to a bus (add up all the amperage of the devices being serviced)? Is there a schematic somewhere illustrating a typical marine battery hookup? I realize there is probably no typical hookup, but something that could be used as a guideline. - Brent

Our 12V Nova Kool Fridge Shuts Down Periodically, on Jul 12, 2016 asked:

Our 12V Nova Kool fridge shuts down periodically on its own accord. Sometimes while plugged in at the dock sometimes at anchor. Last year we installed a new thermostat switch and new house batteries. This last weekend we came into dock and discovered a defrosted fridge. We played with the thermostat switch inside the fridge and nothing. Then turned off the fridge at the electrical panel and turned it back on again and it started right away. Any thoughts? - John

How can I call if my tachometers are accurate in providing accuracy between two engines? My RPMs do not read the same when the RPM synchronizer dial is showing balanced revs. Also, the gauge seems to work intermittently. Is a hand-held optical digital tachometers of any use? If so what brands work on a 2000 Carver 374 with twin Cummins 6BT 220 HP?

Martin, on Jun 15, 2011 asked:

We are currently about 500 nm west of San Diego en route to the Marquesas. My Raymarine ST6002 SmartPilot was working when I went into a Marina in San Francisco but when we came out the control display is reading "Seatalk failure" and the unit doesn't work. My manual says to check connections. I've checked the Seatalk connection in the back of the instrument pod and also the connections going into the computer. There is also a 2 amp fuse on the board next to the Seatalk connection. There is still continuity on this fuse. Nothing I've tried changes the error message. Any ideas on things to try bearing in mind how far offshore I am? I was wondering if our recently installed NMEA connections or else the proximity to the now actively used Icom AT 140 antenna tuner for my Ham radio may have caused a problem or caused RF interference. Just a thought. Anyway if you have any ideas on things I could try it would be much appreciated.

The two Raymarine E120 displays on my 21 foot Grady White have accumulated moisture in them. They are pedestal mounted. Is this normal, and what can be done about it?

The AC grounding connection on my Uniflite 36' is no more. What is going on here? Shouldn't the AC (green) grounding wire be continuous between the AC shore power socket and the AC grounding bus?

To my surprise, the zincs on my Grand Banks 32 are gone after only six months of use. Before, they used to last some 18 months. Why the sudden change?
