yeah to jump a 1/2” gap on dc voltage takes about 100k volts. Sure hurts but that’s about it. No amps...An electronic ignition can go to 60KV, but with a very low current, it hurts but doesn't kill, lol.

In parallel, still 12 volts, HD, tractor trailer stuff gets into 24 volt, stuff I work on uses 30-40 some volts on the injector bank but anything NAFT auto is 12 volt.Most diesels I have seen run a pair of 12V batteries.
They pair 2 batteries to double the amps for high compression motors and pre heaters that take big electrical draw. A Cummins intake heater grid is a dead short across a 1” wide wave plate, red hot.Most diesels I have seen run a pair of 12V batteries.

Unfortunately it’s my life for the past damn near 20 yearsNever worked on them.
At least you will have a job, and are still working. My wife's uncle worked for Caterpillar for a long time.Unfortunately it’s my life for the past damn near 20 years
I am fortunate to have a career, I took 4 months off this spring for covid when school shut down, miss that free time, never had that much time. Built my new grow room then lol.At least you will have a job, and are still working. My wife's uncle worked for Caterpillar for a long time.
Thank you for your service.I was in the USAF for 21 years, worked on high power transmitters on the flightline, and associated wiring.
Kept a roof over my families head and food on the table. Thank you. I've been retired for awhile, my electronic principles are rusty...lol. I was an instructor for a long time also.Thank you for your service.

Ditto, here I will fix it.. lolI think we have sufficiently derailed this thread... Nice typin to ya.
Resistors drop voltage, inductors resist current.I’m starting to only remember when I have to

You can fake a load to change configuration by using resistors to act like a “strip” if you need to meet certain voltages or amps, you could mix different voltage strips in series and parallel and unless I’m mistaken, the sky is the limit if you have the knowledge.
Yessss, see you remember. Lol.. but adding a load will reduce current in the circuit but not total current, well depends but I’m thinking parallel. I’m actually wondering how to protect these f strips i rigged up from runaway, without a shit show of wiring again, like fusing each strip or transistors or something along that line. Wonder if they make really little fusable link. Prob something I could wire in to limit current if the strip failed. Would need 20 1 amp fusesResistors drop voltage, inductors resist current.
I believe that the odds of a strip going to a dead short are highly minimal, if anything I think an LED would burn out causing an open and isolating that leg if doing a parallel circuit. That would cause an increase in voltage to the other legs of the circuit. Even an LED failure in my mind would happen rarely.runaway,
Well I soldered all connections and double checked my strips so I should be ok. Just finished this eve.I believe that the odds of a strip going to a dead short are highly minimal, if anything I think an LED would burn out causing an open and isolating that leg if doing a parallel circuit. That would cause an increase in voltage to the other legs of the circuit. Even an LED failure in my mind would happen rarely.
totally. i think I realize what i was missing now and see why parallel is safer now.In DC world, voltage is the danger. I have hybrid training that deals with high amp 500 volt systems, we were taught back in the day that voltage is the electrical push, I will take a hit from 54 volts and 6 amps before I would try 500 volts and 1 amp. If that makes any sense.
DC voltage clamps unlike AC, at higher amp and volt it’s almost always deadly, when making high voltage disconnects on hybrids we are suppose to have someone with a hook to pull us away if we were to get shocked, kinda dumb because you wouldn’t survive. I don’t know the potential these 2-300 volt ballast have but at a amp output and having a 120 feed in, I’m not willing to try.totally. i think I realize what i was missing now and see why parallel is safer now.
please correct me if I am wrong but I am going to sum all the technical shit you and @raratt just broke down as simply as I can.
on the DC side, in the event of just getting a split second shock, low voltage/high current is going to have little effect, whereas a high voltage/low current could still fuck you up pretty good. and if you for some reason grabbed it for more than a few seconds, your going to be screwed with either one of them.
