I replaced the audio FM radio on the boat. Took quite a bit of fiddling as the radio had virtually no instructions. The RCA outlets to the speakers failed to work but the multi pin connector for the speakers did.
The issue that I have, is that the radio channels and pre- sets are lost every time the power is turned off. I know there is a wire for this (the yellow) but I am reluctant to run anything with constant live power from the batteries except for the two bilge pumps and the little fan for the nature's head composting toilet. I know the current draw is minimal, but every constant power is a potential fire risk, albeit only slight.
I only get to the boat once a week or fortnight, and a small 100w solar panel is used to keep the batteries (2) charged up.
Any suggestions, or should I just run a fused connection to the battery?
I guess all modern fm radio/ stereo units are the same. It can't be much of a fire risk hundreds of thousands of cars are wired that way
Hi Skipper,
Have you measured the (yellow wire) current? I'd expect it to be low enough for even a 100Ah battery to handle it for longer than a couple of weeks. And absolutely to a fuse. I'd have a fuse or CB on anything drawing power.
What batteries and how many Ah?
I had to check my photo gallery to get the answers to your questions.
The set up is 2 x 80 AH batteries (MFM50). The solar panel is 40 watts going to a dual battery solar charge controller. (see picture).
The cable run length to the battery or a positive bus bar I am going to put in is about 1 metre.
If you have a controller for your solar panel just wire the yellow wire to that. Otherwise just to the battery. The drain is minimal and you have bilge pumps connected to the battery anyway so the system is not isolated while you are away from the vessel. Just be careful of stray currents.
Select to expand quoteSophiaChen said..It sounds like you've been putting a lot of effort into upgrading the audio system on your boat, and I can understand your concerns about the constant power to the radio.
It's important to prioritize both functionality and safety in setups like this. If you're still looking for ways to optimize your boat's electrical setup, it's worth considering proper surveillance and security solutions as well. Just like with audio systems, a reliable security system on your boat can offer peace of mind, especially if you're away for extended periods.

Dear Sophia,
I work with Victorian Police. I've never heard of you, nor do I recognize a single 'licensed accreditations' you have listed on your website.
So I've forwarded your website details onto the Victorian Police for verification. I assume that's ok with you, considering you are proudly displaying the Victorian Police logo on your website.
I have also forwarded your details onto ASIAL, the governing body for security licenses in Australia. And ACMA, in relation to your cabling license.
Hope that's ok with you guys. I am sure the apparently false accreditations have a perfectly reasonable explanation.
Please do not hesitate to post more proof of your accreditations, I would love to learn more about you.
All the best to you!
SB
