I'm continuing to sort out the wiring in my engine bay and have successfully rewired the VSR to charge leisure first rather than starter, removed a pile of cables that had been left behind by previous owners adding/removing bits organically, added fuses where there were none, and isolators where I would like them - hoorah!
The last thing I would like to do is add an isolator switch to the starter battery and am wondering what rating this needs to be. According to the Bukh manual the starter is: Gear Driven 1KW output. So, would that roughly translate to 1000/12 = 83amps, and is that continuous or is the cold crank current likely to be say double/treble to get it moving? The switch I was going to use is rated: Rated at 300A continuous (1 hour) at 48V DC and 1000A for 5 seconds.
Thank you
