If your amp is pulling the MAX current from your alternator, you will be in trouble with an e-fan!
right.c'mon bob....i dont drive around all day with my battery disconnected. i have a feeling you know i was outlining the point the 28 amps at max...or 14-18 amps in normal mode were probably not taxing the battery.
my lack of technical ability
i am aware of the voltage spikes, wild ac and all that fun shit....and do have modded alternators to weld with....with my gas engine it was electronically throttle controlled to produce the necessary voltage to run my powertools (brushed of course) and weld. sometimes i weld with the batteries too...just plain ol batteries...all done at home by my inept tiny minded self.
when the batteries are disconected for welding reasons alternator puts out between 13 and 18 volts in normal mode.. when switched to weld i crank it up to 100 plus when i need to use the grinders/drills/sawzall... when welding i control output with a gm type rheostat for interior lights from a jeep. but i only do this because of lack of technical ability.
i dont have a throttle control on the diesel yet, but i plan to overdrive the air compressor and secondary alternator for welding that used to be on my gasser. real estate is at a premium.
but i will get it going as i will need this option again soon..
i am wondering if your ever going to have the spine to realize you may not be applying your knowledge to its fullest capacity and have made mistakes in your attempt to debunk this issue because you can not get around your preconcieved notions....i myself am guilty of proceding with my mind and being a bit stubborn. on this very subject years ago i was exactly like you. but i had to figure out a way to deal with the issues at hand and have come to this point.
i am not full of shit and can prove everything i have and do.
i am trying to not disrespect you because i do recognize you have superior intellect on many many issues...far surpassing me. i have no shame admitting that at all. and that further puts me out ... how you can be wrong and move right past it...and i think you know it too.
your intellectual dishonesty with this is quite surprising
not like i used too. just my lil freq meter building efi harnesses mostly testing map bap sensor.. i may even have a oscilloscope in storage somewhere.You have obviously never used an oscilloscope!!!
And I suggest you google, and read up on what di/dt is!!
This isn't rocket science.
I completley agree. I have an e-fan on my 3.0 and have had ZERO issues with it's reliability or cooling abilities over the last 2 years. I am very happy with it. I was simply saying that theses examples that people are bringing up using other vehicles can't be compared directly to 3.0 Rangers. The thread was not started to argue whether e-fans work in general, but to decide how well they work on a 3.0 equipped Ranger. The only people who can truly answer that question are those who have put an e-fan onto their 3.0 Ranger. Everything else is just conjecture/theory.
Why must everyone everyone disregard the OP in these situations? All that was asked was whether it was best to have two smaller fans or one single large fan, and youve turned this into a giant waste of time. I come to this site less and less because quite simply, anytime someone asks about something like this, they are immediately shouted down and the fighting begins. Can't someone just answer his question? If its a situation like someone posted a few days ago, where water pump is shot, fan blades are beat to hell, and clutch is froze, and you need to replace it all ANYWAYS, then if that person wants to do with their vehicle what they want while they have it apart, answer their questions as relevantly as possible. The patronizing attude of some people on this site is driving me further away from this site and the people on here. I had considered asking if someone could put up a wiring diagram for installing an electric fan once, but realized it would just turn into a thread just like this one.
Thank you. I feel this is whats most lacking. There are plenty of people on here with e-fans and I feel a write-up on this would help those of us who want to try this out. i've tried looking on other sites and have picked up ideas that I'd like to incorporate (like a light that lets you know when the fan is working, a sor of "fault light" to let you know if a fuse is blown or something so you know before your temp gauge pegs out). The one write up in the tech library is a basic illustration of a kit and doesnt seem to really show much step-by-step instruction.
Please refer to post #70.Thanks James! You have just added more reasons to stick with the mechanical fan/clutch!!
