Regarding two kill buttons, by the naming of the switches, it appears that this allows killing the circuit from two separate locations. Which could be desirable.That's good, tal mann!
My comments are as follows:
1. S2 & S3 are to be 'NO' and wired in parallel. By the way, why two 'Kill' buttons?
2. I suppose the cable from the isolator relay 'B' terminal is terminated in a junction box where the cables from the fuse box, starter/alternator and relay R3 coil are also terminated.
3. What is the purpose of relay R3? Doesn't the isolator relay by itself isolate the ignition circuit also? Is the existing ignition wiring required to be altered?

You don’t need two NC switches, unless you want to reset the circuit from different locations. For example, in the engine compartment and the drivers seat. If you only need one location, use one switch. If you need multiple locations, add another NC switch in series with the others.Hi djsfantasi,
It certainly does, but I needed to know 'where ?'.
Many thanks.

No, I mean NC, as they appear in the schematic. I missed that you kep referring them, incorrectly, as NO.You meant two 'NO' switches?
Please understand it's a latching relay and the coil is to be energised to reset. That those contacts should be 'NO', and wired in parallel, is obvious.No, I mean NC, as they appear in the schematic. I missed that you kep referring them, incorrectly, as NO.
