Alternator Done

[mijdirtyjeep]

Well yesterday my alternator took a crap on me!!!!! :banghead My question to you guys is since I have the little 105amp alternator, can I upgrade to the 145amp? I do not feel like rewiring the damn thing, just plug and play. I ask this because I know they came with 105amp, 145amp, and dual alternators, and 105 seems kind of small for two batteries..


thanks

I do not see where a 145 would hurt anything. The alternator has a built in voltage regulator. I would say the worst thing it could do is charge you batteries faster. As far as the 105 goes if you do not have alot of electrical acessories then it will probably do the trick. I mean it has worked this long right?? If there is not a bad price difference then I would go with the bigger of the two but if it is more than 20-30 bucks just go back with the 105

It only seems to be around $10-15 bucks so I guess it is going to be the 145amp....

Oh and the truck was never used to charge camper batteries before, as it has to now.. When I bought it I had to remove the tape and put a fuse in the under hood fuse box.. I have two big batteries in the fifth wheel and camp in the woods a lot. I have a generator, bit hate listening to that thing...

Then I would go with the 145 for sure.

Funny thing is I did not realize it was not charging for around 16miles, my blower fan sounded like it was not running as fast and I looked at the message center and it said Battery not charging. I turned around and drove home without any performance issues, can not do that with a gasser, nice not having spark plugs...

You might get lucky and someone on this sight with the knowledge, figure out the difference of the two alternators. One as to the charging time or run time for your truck while charging your camper. I would think that there might not be a whole lot of difference between the two times, thinking that the other alternator is more need for driving and running high amp items than for charging extra batteries. Just a thought.

I actually found a dual alternator kit, but for $1300 it does not sound like a route I am going to go.. I think just upping the amps a little I would be A OK.. I did find some 200amp alternators, but they require a rewire of the main feed, with an added 250amp inline fuse..

My truck came w the 125 amp one..I found dat out when the VIN check came back!!I'd recommend everyone to have one done..I was amazed when I saw the option list on my truck.
Does anyone on here know how to set up capacitors??I'd like to get more info on that??
That would eliminate the extra batteries and alternators
[I think]
Capacitors just store juice and supply it as needed,but IDK much about them....ANYONE KNOW?????

You could get a older style Chrysler alt and just dedicate the charging circuit to the items you want to keep powered..They are easy to set up,and cheap too.
Keep in mind how you gonna drive it though...I saw somewhere on a diesel forum where a guy w/dually had 2 extra alternators[maybe this forum here??,i dont remember]..

IDK his name but his avatar has a white dually with high-rise power lines in the background....
I bet he could help you out with your project..He has listed what he uses these for and I was blown away by the stuff he is able to power with his set up!!!!
