Re: [Amel Yacht Owners] Masthead lights do not last

Patrick McAneny

I have had all new instruments installed on my boat . Without  being consulted the electrician removed the 24 to 12v converter next to the head and installed 24v bulbs in mast head fixture. Thinking it was something the previous owner installed , I did not object , not knowing it stabilized the current as well as converted it. From the beginning , Joel advised me not to change things electrically, I value his opinions and tried to follow them. When I brought this up to the electrician , he asked me why all boats don't have a stabilizer if necessary. I want to discuss this further with him , but how do I answer the logical question . Other boats have generators and engines that increase voltage , how is that they don't require a stabilizer ? Secondly , they powered all my new instruments with 24v . Are they going to be prone to failure ? I want to have any changes done , if necessary before getting my boat back within the next week or so.

I believe that the charging voltage is, 28.8 absorption and 32+ equalization, transmitted to the Masthead lights.

No I don't think can't get voltage surges with a big battery bank.
IF it could possibly happen you'd be having all sorts of issues with lamps and other 24VDC devices.
The ONLY way you MIGHT have an issue with this would be if you used the EQUALISE cycle on your battery charger while the masthead light was on. The EQUALISE cycle raises the voltage to around 32VDC for a while, but that is something you would rarely do, possibly only if you had flooded batteries that you suspected of being sulphated, and if you know about equalising batteries, you would also know to turn off anything on the DC circuit before starting to do it.
Its much more likely that you have bad connections, salt water ingress into the lamp holder.....
