I have an alternator on an in-board motor in a boat, I have almost completed re-wiring the electrical system and am wondering if it is possible to replace the existing filament lamp.
I have researched and came across a forum discussion which, from my basic understanding, sounds like it is possible but wanted to check and confirm that it is do-able and was hoping that I could get some advice on the resistors/diodes to use.
In the above forum, the OP attached a schematic which has a bridging 5 ohm resistor, a 270 ohm resistor on the anode and a 5 ohm resistor going to the alternator, in this forum it was suggested to use high watt resistors around the 25W mark due to the heat.
Does all of this sound correct, is there a risk of harming the alternator or battery?
Can I use a 12V LED such as this one?
