Bad Diode Stator means?

Q: on aug 4 412pm sorry so...@needadvice.org wrote sorry to keep bugging everyone about this but i just dont know. 77 dodge van 318. on startup ammeter needle swings from full charge to midrange. loud squealing when ammeter needle swings to full charge. noise goes away after engine warms up. i think i tried tightening the belt long time ago and made no difference. visual inspection of belt appears ok. it is one of those kind that is serrated on the pulley side but no glazing or obvious wear. looking at a shop diagnostic report sheet from long ago it is somewhat illegible but says under alternator output bad dode stator which i guess legibly written means bad diode stator would this cause the noise the belt looks ok and i brought the alternator down to autozone for them to test on their machine. test said it was ok but mgr. there said it was probably a bad diode in the alternator. should i buy a new alternator and see if the noise disappears ======= ======= informative diagnostic post.... good for you..... addressing your last question in the post........ no!!!!!!!!!!!!!!!! not yet. the needle should raise on any vehicle momentarily after startup as the generator recharges the battery. fact not fiction i would not condem the altenator yet as long as the charging system seems to be doing its primary job and your main symptom is the noise. keep your money in your pocket for now. now ..as to the topic and your main concerns... being a tech....i wouldnt suspect the stator making the noise but that doesnt eliminate the fact that it still could be the altenator making the noise or the stator for that matter. quite frankly....i dont know. i defer to higher minds which will be with you shortly if youre patient. on closing..... you should be informed that i am not..... a fan of autozonedout parts.....especially electrical anything!! with that said....... still..... jest to see........ you could always....carry it back if the noise didnt go away or..even if it did. and.....i wuddnt feel to baddly bout doin it if i was you...after all.....the dealer techs do it all the time. marshmonster takes a sip of his shroom juice...and tries to remember what the inside of an altenator looked like....20 years ago .

i have not started to remove parts yet so i dont know if i should use the special tool or if i can use my generic set with either a shorter bolt or with the vibration dampener as a spacer in conjuction with the stock bolt. i realize that the depth of the special tool will provide a more square seating provided the depth of the hole in the timing chain cover is greater than the depth of my generic set. just remove the old seal and install the new one when the covers off. no special tools required at all. it sounds like the dodge tool is for replacing a leaking seal without removing the timing cover. see http//www.pavementsucks.com/tech/timingchain.php for lots of good reference pics. .

im preparing to replace the timing chain on my 99 dodge ram 5.9 gas engine which also means replacing the front crankshaft oil seal. i have a generic oil seal installation tool kit that looks like it will work but the depth of the various size disks is only about 1/4 inch. the service manual calls for dodge special tool 6635 with a depth that looks to be about 2 inches and the manual says to use the vibration dampener bolt in conjunction with the special tool to draw the seal into position. i have not started to remove parts yet so i dont know if i should use the special tool or if i can use my generic set with either a shorter bolt or with the vibration dampener as a spacer in conjuction with the stock bolt. i realize that the depth of the special tool will provide a more square seating provided the depth of the hole in the timing chain cover is greater than the depth of my generic set. any thoughts regarding whether i should buy the special tool would be appreciated. .

it was very strange. i would really like to know how the 59 car right rear got creased. maybe 55 did it under yellow and 59 retaliated by spinning 55 out. then 55 re-retaliated by spinning 59 out. i read according to the rules since 55 failed to proceed with caution then the results of not proceeding with caution became his new position. in any case its a bad deal when a guy leaves the trailer with a brand new copy of the rule book in hand. if anyone missed the race just go to youtube and look up mike wallace geico commercial with warren loren wallace. you will get the idea. yep. much more entertaining than watching an oval race in my opinion. it was one of the strangest one ive seen. im thinking gordon was screwed big time. .

i thought they never had anything except the nv4500 behind the 5.9. great info from you once again but i think you are confusing part of it with the person that posted about a 5.9 into a 5.2 dak. my nv swap is to replace the 46re in my 98 5.9 zj jeep. the nuts and bolts of this swap seem pretty straightforward. i knew about the 5.9 balance and using the right flywheel but i did not know about using the 5.9 pressure plate with a 5.2 clutch disc. i wonder if those parts can be bought separately i plan on using the computer from a 98 5.9 manual ram. i know the pcm and harness are physically direct swaps with the jeep parts but i might need a wire or two swapped/added/deleted at the connector. the deal in ma is the emissions inspection machine enters the vehicle vin right out of the pcm and it has to match the actual vehicle vin so i need my vin in it. still having a heck of a time finding out if it is possible to burn my vin into a used pcm out of another truck. i hear you cant flash a vin if the pcm already has one but i have also heard there are ways it can be done. still researching that part of it. i can get it flashed into a new or remanufactured pcm for the same application but id like to keep this swap to used parts if possible. ill be posting in the next day or so about the jeep/dodge/46re/nv3500 transfer case swap compatibility. maybe youll be able to help on that too. thanks again folks - john. . 222 337876 foiti.33016$c96.30682@svr23..prodigy.net on sun 5 aug 2007 001249 +0200 cest sorry sorry@needadvice.org wrote sorry to keep bugging everyone about this but i just dont know. 77 dodge van 318. on startup ammeter needle swings from full charge to midrange. loud squealing when ammeter needle swings to full charge. noise goes away after engine warms up. i think i tried tightening the belt long time ago and made no difference. visual inspection of belt appears ok. it is one of those kind that is serrated on the pulley side but no glazing or obvious wear. take a ten dollar bill and go get a new belt and a piece of sandpaper. use the sandpaper to lightly buff the groove the belt rides in. just enough to breakup any glaze that might be present. put on the new belt and tighten it properly. no more problem. replace the third lugnut on the left rear tire at the same time. steve b. it is easy to test too. just spray some wd-40 on the belt when the noise is happening........... if it goes away it is the belt. ed .

is there a standard for the proper sizing of an ac/hvac unit to a home absolutely. it starts by calculating the heat gain. if you havent been doing it for 20+ years you need to do the calculations. that means either sitting down with paper pencil and manual j and figuring the heat gain or getting a computer program to do it for you. put in too little cooling and it wont keep up with the heat gain. put in too much and it will drop the temperature so quickly that the system doesnt have enough time to dehumidify. hvaccalc http//www.hvaccalc.com is a pretty nice program and at $50 for residential use is pretty cheap. try out the demo and see what you think. .

it may have an electric transfer case shifter and that would be a rotary switch on the dash. none of the older rams that i am aware of had full time 4wd and i doubt that the daks did either. i cant say for the newer ones but i dont remember seeing it on the web site. -- if at first you dont succeed youre not cut out for skydiving anyone have any experience with transfer case swaps between autos and manuals or between jeep and dodge does a dodge transfer case from an auto trans bolt to a manual trans and vice versa. im pretty sure it does on jeeps. can transfer cases be swapped between similar jeep and dodge vehicles like from a dodge 46re to a jeep 46re i thought there might be a clocking/bolt pattern difference between jeep and dodge. were many or any dodge daks or rams 4wds equipped with awd transfer cases rather than the lo/hi/2wd/4wd type i looked at one of our company dak 4wd trucks today and couldnt see any type of shifter except the auto shifter on the column. i was only looking through the window though. i believe it was a brand new truck. .
