All I'll be looking to do is maintain a 24V system which is currently in good condition; I've acquired a civilian Mitsubishi Jeep from Japan which, apparently, shares an electrical system with their military version. I was wondering why they overspec'ed their electrics. I once had an ex-Canadian M38A1, a 1967 Kaiser which had a 24V system. I learned that components were not as readily available and more spendy when they were, but were not often required. Bulbs, everything lasted longer. The difference is that the Mits is not set up to be submersible, and I was wondering if there was another reason they left it 24. I reckon you're right, Fred. Standardization is it.
