Q: max does not matter how long and how often you argue the facts - you are wrong. prove it. you understand ohms law yup. you know how to calculate effective resistance voltage and current in series circuits certainly do. you can only increase or decrease voltage or resistance directly - and the current responds accordingly. wow how succinct. in a series circuit the total resistance of the circuit is equal to the sum of all resistances in the circuit. duh. your headlights are 60 watt high beam units and there are 2 of them in parallel for a total of 120 watts. watts are volts times amps so the 120 watts of 12 volt lamp draw 10 amps. great so with an 850 amp battery how much voltage drop is there add an alternator capable of 100+amps and what is the drop none comes to mind if you had a real nasty wiring system with 2.4 ohms of resistance to each bulb the wiring and the bulb would share the voltage equally. the bulb would get 6 volts and the total current draw would be 2.5 amps per bulb or 5 amps total. this is very unlikely funny i recall saying the same thing back at the beginning of all you jokers telling me im wrong. now you have .024 volts of drop without any corrosion or problems. so less than 1 volt which is what stern claimed and i said was wrong damn you just proved me right. corrode a couple connections and burn the contacts a bit on a switch designed by accountants and you soon have your .24 ohms of resistance and your 1 volt voltage drop which is ten times what is allowed as acceptable. a one volt drop from running voltage of 13.5 +.... wow thats 12.5 volts or a little better than the designed voltage of the lamp. damn im right again. note - the battery is still at 12 volts. the headlight sees less than 11. wrong. with the system running i assume you drive after dark with the engine running i know i do the voltage sits at 13.5 or so. ok you say the electrical system is designed to run at 14 volts. the voltage drop just went from 1.0896 to over 1.2. ok.... 14 - 1.2 = 12.8 damn there it is again!!!! all this 12.5volt approx popping up youd think the engineers planned it that way....do they have access to the same math you have wtf part of its unlikely to drop to 11v do you not understand i mean you just freakin proved what i said after calling me wrong. jeez...... whatever..... shakes head in amazement max life liberty and the pursuit of any jackass that threatens it. embellished usnavy slogan .

i have a 98 dakota 4 x 4 automatic 3.9l v6 with 73000 miles. lately when the engine and tranny i suppose is cold the transmission resists shifting into drive. it shifts normally from 1 2 butfrom 2 3 the rpms will surge past 3000 before i let off the accelerator and coast along at perhaps 20mph. after a few attempts at accelerationit does then shift into normal drive 3. no problems downshifting. the problem then does not repeat until i once again start off with a cold engine. there is a manual od off switch which i never use no towing heavy loads or hills to deal with. i did have to add 3/4 a quart of fluid this past summer but see no leaks on driveway. is this a vacuum leak will a simple trans oil and filter change offer help or flushing do i need to replace the vacuum modulator or perhaps i should try the fluid and filter change first to see if that helps. any advice or experience with this problem will be greatly appreciated. i have read somewhere about tranny fluid escaping past a seal into the engine from the modulator and this would explain my not seeing any leaks when i discovered a low trans fluid problem this summer. apparently the tranny fluid can soften vacuum hoses...does any of this make sense thanks dave .

just saw this on tv. chevy with duramax engine has more power than ford super duty trucks. sure did not mention dodge -p and even at that theyre technically wrong. the duramax is rated at 310hp the powerstroke is rated at 325hp. chevys got ford beat on torque with 605lb.ft. vs. 570lb.ft. then of course theres the little ol 6-banger with 610lb.ft. another interesting fact about the chevy package is you can only get the 310/605 engine with an automatic... they de-tune the engine to 300/520 for their manual gearbox. so if comparing manual trans trucks dodge is on top with 325/610 ford is second with 325/570 and chevy is dead last with 300/520. poor little guys... what is the red line on the chevy and ford diesel any word on the new dodge six speed al 2004 600 ctd six speed 4x4 .

im out in the california desert for the winter and just got a obdii code of p0441. the site says evaporative emission control system incorrect purge flow. is this something to sweat or is it just from all the rain we have been having. we were hooking up and moving our trailer to get water when it came on. any help will be greatly appreciated. doug .

check the abvious glove box lite under hood lite and then you may have to pull fuses one at a time start with pulling the iod fues first and leave it disconnected because the door being open will always show a drain you dont need an amp meter just an old fashioned test lamp or another kind of bulb my 2001 maxivan has started draining the battery overnight. its a new battery the alternator is charging producing enough juice to charge it etc. any recommendations on the most likely culprit my approach will probably be to put an ammeter in the battery circuit and start pulling fuses until the drain stops but id just as soon have a bit better idea which circuit might be the likely place to start. any advice is welcome -- thanks mark sparge .

not much else we can do for you max. electricity just isnt your thing. interesting given you proved exactly what i said to begin with. i said resistancewould have to be significant to cause voltage to drop to 11v. your math proved that even in the worst case scenario a properly operating system would only drop voltage 1.2v. i said that the system was designed to hold voltage at 12.0v or above. your math proved that a drop of 1.2v in a system operating at 14v would still show 12.8v in the circuit with all that resistance. i said that the claims made by mr. stern were an exaggeration. your math proved it. you said there isnt much else you can do for me and i have to agree since you proved exactly what i said to be true. now if you want to say that replacing the wiring gets you more than 12v sure it should. no doubt it would. but to claim the stock wiring drops voltage to 11v without proof paricularly when the proof you have shows it would be 12.5v is silly at best. maybe thats why i dont trust the lot of you who claim im wrong then provide math which proves im right. max life liberty and the pursuit of any jackass that threatens it. embellished usnavy slogan .

excellent - i have already bought a #20 torx socket but ive been unable to find the part locally. where did you find it .

thanks for the info. it looks like $2000 to make that happen. it maybe worth it. whered you get told $2000 and for what it will be the automatic trans. what upgrade is needed typically a new torque converter and modified valve body. you may be able to get by with just a valve body but the problem is if the torque converter clutch starts to come apart it ends up trashing the rest of the transmission. the o/d section is also comparatively weak in the context of 600ft.lbs. and not much short of a rebuild can address that so plan on taking it easy when in overdrive and only hammer on it when o/d is locked out. figure on $1000 to $1400 for a torque converter depending on brand and about $400-$500 for a valve body again depending on brand. installation time is about an hour on a valve body and 2-3 hours for a torque converter need to pull the transmission for that. .

i was told that there is minor differences between the newer 600 ft lb diesel and the older model and i could install a performance chip to get the same results by installing one. well id say its a little more than minor. the block and head are similar but thats about the extent of it. the 600ft.lb. engine has entirely new fuel and induction systems sharing virtually nothing with the original 24v isb engine. however the engine in your 99 is still electronically controlled and you can increase the hp by the addition of an electronic box. now that doesnt mean you just plug in a box and go nor is that the case on the 600ft.lb. engine either. to add 200ft.lb. of torque youll be increasing your power output by about 90hp thats rear-wheel. you didnt say whether this was an automatic or manual transmission. if its an auto youll need to upgrade the transmission to handle the extra power. youll also need to add an auxillary fuel pump as the stock pump may have trouble keeping up with the increased fuel demands and the stock lift pump on those engines is a known weak spot anyway. .

horsepower almost doubled. adding performance boxes will add power but only add significant power with the 3rd gen. trucks. well i wouldnt say that. a tst powermax3 or an edge comp can add significant power over 100hp. and as far as doubling the hp from the isb to the isbe not really. the ho version of the isb made 245hp. the hp rating on the latest isbe is at 325hp. i believe the lowest-rated 24v engine was 215hp with an auto. .

every year represents at least one change and they are significant. in addition the 99 is 2nd generation. the 03 04 and newer are considered 3rd generation. the big difference between the 2nd and 3rd generation is the move from the mechanical pressure/time pump injectors to the new common rail fuel injectors. engine noise is drastically reduced with the common rail and horsepower almost doubled. adding performance boxes will add power but only add significant power with the 3rd gen. trucks. thannk for the great info. it seems to me that i would be able to get 600 ft lbs of torque out of the 2nd gen engine. i know dodge still sells 400 ft lb torque engines and the c 600 costs more than the regular. the chart for the 2nd gen shows the ho at 500 lbs while the 24 valve at 400 lbs but i am only speculating further info can be obtained on the following site http//www.dieseltruckresource.com/ steve i totaled my ram 1500 reg cab earlier this year. i really liked it. i have decided to get another 99 this week a 2500 ext. cab with the cummings turbo diesel. i was told that there is minor differences between the newer 600 ft lb diesel and the older model and i could install a performance chip to get the same results by installing one. is this so can anyone point me to some links that has discussion on it or a place that sells the chip does fuel performance go down i would think it would. thanks! .
