Not really. Don't wanna sound like a n00b But could someone explain?
-
is 1.5 after you wired them in parallel?
no, SERIES.
well, something isnt right.
what is your ohm reading per coil?
series should increase the resistance not lower it.
All 4 VC measure ~4.4 ohms. I am using 10 ga speakerwire that has .5 ohm resistance when measured. I wonder if that extra ohmage is from the wire??
did you do this?
because thats the only series/parallel you can do. unless you did just series, which means you'd get like 16 ohms.
your wiring is fucked up somehow, or you're using the wrong wiring terms
nah you can wire negative to negative, positive to positive: http://a248.e.akamai...ono-low-imp.jpg
series: 1 ohm.
That's wiring in parallel, not series. You might be seeing the resistance in the leads of the multimeter. Touch the leads together and see what it reads...if it reads about .5 then that's where the extra .5 is coming from, and means your actual load is only 1 ohm, not 1.5.
LMAO sorry for the confusion between the 2.
It does read. .5 for when the 2 are touched. I just changed the batteries on the damn thing, and need to recalibrate it (kind of suspected). Thanks everyone for the help. -

I have 2 L7s DVC 4 ohm. Checked the resistance on the series and it reads 1.5 ohm. I wired for 1 ohm. Is this normal?

if you are using a skilsaw make sure to use another MDF board to guide along. clamp it down. PLEASE do this. I made a 30$ mistake by trying to freehand and my plates were crooked. Had to get another one.

If you mean the belt tightness, there isn't any play. It's on there pretty tight.
-
Sorry for the misinterpretation, it was whatever it was shipped with I must have measured wrong with the pulley walls. The belt tensioner is newly replaced and What do you mean the range?
-
If that's the 1MZ-FE Motor it does idle quite low (I used to have an Avalon with the same engine). It's most likely not the fact that your belt is slipping. It's most likely do to the fact that the alternator is not reaching it's turn on speed. If you increase the RPM by 100-200 or so does the alternator begin to charge? Remember, give it about 5 or so seconds to see if it actually begins to work. You can tighten that belt more to try and see if it helps but honestly I would say that you're having a turn on speed issue. Also, take a picture of the alternator so I can see which one it is.
I believe it is that too. I'm trying to see if i can get on overdrive pulley that is probably 1.75 and that will only do 21k at redline. But also my a/c compressor pulley is kind of lagging, and may be causing some drag on the whole belt. It should begin to charge at that speed, but i think the ohter pulley is now affecting it...and what picture do you need to see?
-
yes, i have done this
-
Is it possible to put a 1.75 pulley on the alternator? This will only bring the max rotation to about 20.5k
-
what car might help to know the model the voltage might be regulated by a computer
It is a 1996 lexus es300. Crank = 6", alt = 2' = 3:1 and redlines at 6000 RPM
-
I can help you find the ratios, but you need to post the info I asked above
Mechman said it was a 3:1 ratio
At no point did I say that you have a 3:1 ratio. A couple posts ago, you said that you had put the OEM pulley on our alternator, which would DEFINITELY cuase low voltage at idle. Bumping this thread without the info we need is not going to get you any help with your problem. Please go out to your car with a measuring tape, and measure the diamter of the pulley on your crankshaft, and the diamter of your alternator pulley so that we can solve your issue. Like the other guy said, untill we have concrete numbers, we cannot figure out your problem.
Matt
I was going off f some phone conversations we had on the phone. And it is in fact a 3:1. 6 in crank, 2 in pulley (which was the oem size) But my engine begins to redline at 6000 RPM. any suggestions from this?
-
under drive pulley is on the crank???
Just the OEM crankshaft.
-
I was suggested not to do this on an aluminum pulley.

I will have to do the calculations when I get home for the ratio. It is the stock pulley that was on the OEM alternator it seems like. My tonight of the engine is a bout 500-650. It's a 96 Lexus es300, Idk If someone can find the factory ratios. But I sadly have No clamp meter.
-
No load at all. That's the thing.
-
Well I got the gatorback, and still No help, I can't have it charging that low. Do I need more grip or What??
-
When I'm at idle, my charging light comes on, and my voltmeter reads around 11.2/8 (the engine sounds like it is about to repeatedly stall out). But when I am over 1500, it goes away and starts charging at 13.7. Me and Matt were guessing it was slipping somewhere- so I went and got a gatorback serpentine belt. Thought it would fix it, but to no avail. All the pullys look like they are spinning at the same speed. The overdrive pulley looks fast as well. My thing is what could it be? And if it is slipping, where? What can I do to fix? pleas help. i'm beyond frustrated....
-
Also, the tension is pretty tight, I'm not trying to strain any bearings....

Sandpaper, bondo, and a fair bit of time and correct minor misalignment of pieces. it won't fix half inch gaps or things like that.
Its a quarter inch =/
It does read. .5 for when the 2 are touched. I just changed the batteries on the damn thing, and need to recalibrate it (kind of suspected). Thanks everyone for the help.
1.5 ohms for a 1 ohm series?

Sounds good man. I appreciate it. Makes sense now.
