Hello,
My question is regarding boat electronics.
I have a boat, and I'm using isolation transformer in order to transform 220V to 110V. Recently, the boat's reverse polarity indication light is on. I've opened the circuit to see how this indication is measured and saw that there is a diode and led connected between the neutral and the ground.
Then, I've realized that in the current situation the output of the transformer is basically floating, therefore the neutral line can have any voltage. One of the solution that I've seen online is connecting the neutral line at the output of the transformer to the boat's ground. So I have several questions about it:
1. Is there advantage in connecting the neutral to the boat's ground over working with floating voltage?
2. Is it ok to make this connection?
3. For about a year, the indication was off, what can be the cause for it to be on now?
Thanks in advance,
Ilia
