Seattle Boat Show 2021: Marine Electrical Systems Troubleshooting

Рет қаралды 34,363

Күн бұрын

This is the second 45 minute video I did for the Seattle Boat Show. Our Boat Show University courses worked out very well this year, being all virtual. It'll be interesting to see when things are back to normal, how much video and other virtual tools will be used.
Electrical trouble-shooting is always a challenge. I tried to make this a little different than some other presentations I've done (no power-point), and I think it turned out OK. Watch this, purchase/make some tools, and practice on your own vessel!
If you didn't see it 'live' and have questions, leave a comment and we'll get back to you.
As always, if you or someone you know is interested in a Marine Technology program, check us out! We teach people how to fix boats, and be part of a great industry. More information: www.skagit.edu/academics/area...

This is the best educational KZfaq video for the non electrical person with a boat

Thanks for the nice note! I'm going to try and make a couple more this fall! And, of course, lots of Tech Tips in the works.

Decent overview but a few comments. The voltage checker is commonly called a chicken stick. The bigger clamps are battery clamps not alligator clamps. A microfarad check is for capacitance. Ohms are for continuity. Fuel gauges must be paired to the sender and not all senders are full ground = full/pegged. Some sensors might be 5v on newer engines. The starter has a solenoid on it and that is a relay. All motors and most gadgets have the required voltage and draw in amps on them so this can be useful for checking condition. Just like older cars many previous owners upgraded/added things without electrical knowledge. If there are splices in the system or other obvious modifications check them out as a potential source of overdraw or other sadness.

bluetooth meters are awesome too in the times when you cannot get a visual on the meter when you're in another part of the boat. I highly recommend the Hioki CM series such as their 4372

Yes, Bluetooth is great - I personally have a half-dozen meters. I got.a removable face before the BlueTooth technology came out. My Fluke 375 works well, I have tried a Hioki.

Could you break down the components for the make it yourself breaker? Is it just a 15 amp breaker with attached 14gauge wire? Thanks! This presentation deserves a reward!!!

@SVCSkallywags Жыл бұрын

Glad you liked the presentation. Yes, I've made and used a bunch of variations. 15 or 20 amp breaker. #14 or #12 wire with alligator clips. I usually do between 18" - 36" length. If I need to use it to apply power to say a pump, further than that from a source of power, I keep a 15' or so with clips on both ends. Going to work on more videos this fall!

about ghost voltage, I used to use an 1156 bulb inline of my volt meter when looking around for ghost voltage but since I use the Loadpro from Electronic Specialties. It is much easier and allows the tech to introduce a load at will by means of a momentary button. its Perfect or confirming if that fuse really "is" good or if its just good enough to pass voltage and satisfy a traditional volt meter test. thing has saved me time especially when working on trailer wiring

@SVCSkallywags 2 жыл бұрын

Yes our students get a lesson with the LoadPro - also we have Dan Sullivan's book that goes with it. I had to keep this video to under 45 minutes - maybe I'll put together Part 2!

Really like your video. Great tips. I have a question. You have a 25 foot, 14 gauge wire for testing. I noticed that there is no breaker on the wire. Is there a reason for that?

@SVCSkallywags Жыл бұрын

Its just an extension jumper. I always use it with the breaker for OCP when testing

@jonerasmus9399 Жыл бұрын

so at 19:49, if the switch is open you get 12 volt , when you close the switch and get 0 volt the switch is fine

@SVCSkallywags Жыл бұрын

Correct! A closed (good) switch should be zero volts in an active circuit. The one that confuses people is the 12 volts (on a good/active circuit) when the switch is open

Mr. Beemer, I have 4 or 5 unused Blue Seas Breakers (15 amp) that I would like to donate to the Skallywags (like you show at 4:00). Does your program accept donations? I live in Anacortes

@SVCSkallywags 2 жыл бұрын

Yes, that would be GREAT! We can always use those. You can drop them off at the front desk with Misty, or if you want, you can email me to set up a time to drop them off and say "Hi" Email is in the video descriptions.

Hello there, I came across your video because I’m trying to figure out how did all my gauges stopped working all at once when I added a second battery on my boat. I have. 2001 regal fastrack . The boat turns on fine but no cluster . I checked all relays and fuses and is all good . There’s power going to the cluster plug . Any help I’ll appreciate it thanks

@SVCSkallywags 2 ай бұрын

OK - if all gauges stopped it's more than likely 1 of two things - power or ground. If you checked fuses... then it's a ground - the only thing common to all. However, use a multi-meter and make sure you have 12 volts at the back of one of the gauges. Test from the positive post to the negative at the battery (key)

@steveo692 Ай бұрын

Hi Michael, great video!! Im interested in getting certified to work in this field. I currently have an A.A.S in Electronics Engineering but love the marine industry. Is there a school that you know of in NJ to assist me?

@SVCSkallywags Ай бұрын

Two closest are - IYRS, International Yacht Restoration, and the Landings School. I've been to both. Private, so more expensive than our Community College, but good schools.

@Do-iz6qd 2 жыл бұрын

I've got a question I hope you can answer. I used my multimeter today and put the positive probe on the positive terminal of battery and negative probe direct to the hull (aluminum) and got 13.24 volts. Is this normal or bad? It's a trailer boat. Cheers

@SVCSkallywags 2 жыл бұрын

Normal -> the hull is at 0 volts or ground, so testing battery positive and hull you get battery voltage, 13.24 means you probably had battery charger plugged in. On larger boats, it's best practice to keep everything electrically isolated from the hull, but totally fine on small outboard powered vessels.

@Do-iz6qd 2 жыл бұрын

@@SVCSkallywags Thanks for that..nothing to worry about, cheers. Got another question while I'm here if that's ok, is it right to work out the correct fuse for a 12 volt accessory that you multiply the amps of the accessory by 1.2 to get the correct fuse rating?

@SVCSkallywags 2 жыл бұрын

Usually the manufacture will call out the fuse. It will be larger than nominal, however the most important thing is that the fuse is below the allowable amps of the wire size - fuses are to prevent "fires in wires"

@Do-iz6qd 2 жыл бұрын

@@SVCSkallywags Makes perfect sense. I was looking to put up some older LED lights and I couldn't find the manufacturers fuse size which is irrelevant as wire size is the determining factor...had it arse up . So I will buy a wire gauge and put a fuse in under the wire gauges amp rating. If wire is rated at 7.5 amp a 5 amp fuse will be ok. Cheers for the assist.

@joefish6546 2 жыл бұрын

You are just telling, not explaining. For example, at 12:29 why does connecting S to Ground fully deflect the gauge?

@SVCSkallywags 2 жыл бұрын

Sorry about that, but I have to keep Seattle Boat Show videos to 45 minutes! Never enough time. Those quick checks will tell you if it's the gauge, sender, or wiring. Maybe for next years video I can focus on specific topics.
