  1. A three pin flasher is + and output + and also - . if you chassis ground with - & connect to - pin on flasher unit, then + on flasher unit with output + going to light fitting you can test without motor going. Make sure the bike ignition is turned on.
  2. Ahh...its for a flasher unit, I would just swap out the flasher unit like IT mentioned above, otherwise go back to incandescent lights...You are not lowering the load by adding the load resistors. Unless the goal is a different look or something?
  3. What type of light is this? And what does it do? What are the specs or do you have a link to the LED you have replaced it with? I ask as I suspect if might be a capacitance issue or maybe just a bad contact? If you are certain you need a load resistor, then based on a 10watt/12v globe, the resistance you are after is 14.5ohms. But that doesn't make sense at all because, why would you just throw away current as heat? when you are trying to save it by using a LED bulb?

  5. If you have access to an oscilloscope and can use one? you could test it's output and input. There will be a common ground and a input signal with a AC signal that the unit is rated for ie; 50kHz, 80kHz, 200kHz, 235kHz, etc. The output signal will be similar frequency but the amplitude will vary a lot. If you have a frequency generator handy as well we can measure the impedance magnitude and series resistance. Those two figures should be very close if the transducer is working mechanically correct. But. You could also check that its output is working by turning it on briefly and listening to it from its side, you should hear a consistent clicking noise that is reasonably quick or a slight hum. It will be faint, so do it in a very quiet place, or record with your phone and boost the volume on playback. Don't run it for long out of water, it could over heat if its a high output model and don't hold it up to your ear from the bottom. YMMV

    Jigsaw blades?

    How tight of a radius could you do? I need to cut two 190 mm round holes.

    Jigsaw blades?

    Do you have any pictures of the blade you acquired and how long did each one last? I am cutting 12mm - 15mm solid polyester based fibreglass.

    Jigsaw blades?

    Solid fibreglass is very very hard on jigsaw blades it seems. What type of blades have people had success with? Or do I just need to buy lots?

    Bilge + Locker paint

    Now thats a novel idea.

    Bilge + Locker paint

    Yeah I saw that, but with limited replys and its now 7 years later I had figured that things would have changed?
  11. What is everyone using for bilge and locker paint? I have been recommended Bilgekote and use this with Yacht primer from international paints. Are there similar alternatives?

    I have been observing PHAD been given some attention and a lick of paint over the last few months in Whangarei. She is a nice looking critter.

    My suggestion is to replace them with a reasonable quality AGM battery. Now the reason I suggest this is because all your current equipment with a little bit of adjustment to the settings will almost certainly charge AGM batteries properly. The other chemistries you have looked at from various lead carbon variants to lithium need very specific charging parameters and it very likely all your charge sources will need replacing or hacked/modded to work. AGM would be plug and play. Also, the amount of use you mention, if we say you used the boat once a week and did a 50% discharge each of those times a AGM will give you 500-600 cycles @50% = 10 years-ish if charge source are set right. They don't leak and are immune to heeling issues. The have lower internal resistance than the FLA's you currently have , so will charge faster in bulk charge off the alternator, that is if the alternator will allow it and to a higher SOC before absorption. Mount your solar and use the solar to do the slow donkey work of topping the AGM's up to 100% SOC and managing the float. Over all the exercise will be simpler and easier to do that other battery types. Weight vs Ah is a good indicator of quality with lead acid deep cycle batteries and if your worried about stuffing up the stern with your solar, make it removable for when you don't want it there. Anyway, just my thoughts.

    Carbon foam

    How often are you on your boat? Live aboard? Weekend sailor? How big is your current battery bank and what do you run off it? Fridges? pumps? chart plotters? toilets? etc.

    Lateral, what is your plan? It would be so much easier to give you advice if you could tell us, what you are wanting to do, what is your current battery bank size and what loads do you run and in the future, how often are you using the boat, what are your current charge sources, ie Alternator with or with out external regulator, solar, wind, etc.
