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?? 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.

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.

Mechman 270A low idle voltage/slippage

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? -

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? -

Is it possible to put a 1.75 pulley on the alternator? This will only bring the max rotation to about 20.5k -

It is a 1996 lexus es300. Crank = 6", alt = 2' = 3:1 and redlines at 6000 RPM -

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? -

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.... -
