That’s one way to do it but using the 12v acc. terminal on the alternator would have accomplished your power supply goal while leaving the primary 24v system more reliable with less load, resistance and fewer parasitic energized components on board. Good job though. 👍
Mine has a 24 volt "civilian" alternator, no 12 volt output on it. I also dont think its good to run high amp accessories directly off of any alternator. I think its always recommended to run them from the batteries. Car stereo amps as a example. I never see people wire the amp directly to a alternator..always to batteries.
Not a bad idea however I run Emcomms utilizing civilian HF radios. Most of those switching converters create way too much EMI and RFI on the HF bands. I would opt to instal an auxiliary 12 volt battery under the rear passenger side seat Fed by a fused line capable of at least 60 amps DC to the aux battery from the 12 volt post of the alternator and from there instal the fuse block next to the battery to feed various equipment. Out of that fuse block you can feed a second fuse block up front to the radio mount over the dog house to feed radios. Any cables run under the passenger compartment in the chassis area should be protected with split loom tubing that is taped shut and then run through tight fitting grommets when entering the passenger compartment. Words of wisdom for those who might venture into purchasing a Hummer for Emcomms or SAR work.
M998-as @jaxturner7288 said, that is only one way to do it. Totally depends on which electrical system you have on different trucks. The later ones with 200a alternator, had the 12volt tap on regulator. Well known solution on that style is to wire off of "rear" battery. Won't go into it all here, people can do their own research. And I hope you carry a fire extinguisher with you and all that spaghetti wiring!!
