Yes I took the batts out a couple times still nothing. I'm going to splice into the wire before the fuses and see I guess.

Any luck?

Ok more poking around with meter.
I disconnected sense pins, and got the same results. I then attached a different atty with a 2.2ohm build and it read
3.43v(low) 6.01v(high)
But the real kicker is the my low reading for the 2.2ohm was where the high reading was for .6ohm build.. And the high reading for 2.2ohm was where the low reading for .6ohm was???????
Im so confused, and a little scared to use it ATM lol
***edit***
Tested two more attys, one with a .6ohm build like original, second with a 1ohm build..
These work fine just like the one with the 2.2ohm coil, so it seems my problem was with my TOBH atty....
Still would like to know why my 1s-6s screen went bad... Before i put in another one(this time small 3 wire volt reader)
So right now Im rocking it with no screen, and i haven't re attached the sense pins yet...

I think you hooked it up right. I have been playing around with one and ran it all thru pin 1 on the 1s-6s and ground the the battery and it worked ok. I still need a dremel and some hand tools before I can mount it.

Did you figure it out?

Yeah it seems to be working fine with every atty except my TOBH, everything reading fine through my multimeter, i still done know why my 1s-6s screen quit working...
Im ordering one of the smaller 3wire voltmeters tomorrow.
I gorilla glued a magnet in crooked so ima try and get it out with some kind of solvent; or maybe try sanding it. It makes one corner of my lid not fit snug and it driving me crazy lol.
Once all that's done and i get all the small details i wanna keep working on. I plan on sanding it up and taking the hammond lean away, then painting it.

Hey do you have a pic of the wired chip before heat shrink? Congrats on your build!

I didn't take one but I have five more chips to build

Hey when you build another one you mind taking pics of how everything situated before shrinkwrap and all that. You uavr so much room in that thing compared to mine.

 

[Greg Figlar]

yeah i will but all i do is solder all my wires zener and resistor and individually shrink wrap each lead then bend each wire up and to the right and then i shrink wrap the bundle of wires then wrap the chip and do the same with the fets and fuses then lay them side by side on the side of the batt sled (but you have to dremel the bottom right corner of the sled to go around the screw post

Yah the lean on mine bugs the crap outa me, its a 10a by the way. I have a 20a will get all the parts to put it together in the next couple weeks. The first one so it wasnt a whole lotta fun if you know what I mean. The next round will be better im sure.

Oh yeah i know what ya mean, soon as i get my new screen the plan is to dremel/file some more room. And tidy it up in there hopefully make it look nicer

i hate to ask this but does anyone have a complete parts list for this mod.my cat broke my laptop knocked it off table and broke the charging jack internally and ive lost almost a years worth of collecting parts and stuff i needed to build this mod and several others i had been researching thanks for any help i can get

The wiring diagram(picture) in the OP is updated to reflect latest part list.

 

[dougward1960]

yeah but its not got the different trimmer resister people are using now with the numbers on it so i thought there must be an updated list thanks though

Here is the part number for that 93PR200LF, but yeah it is back order everywhere you could get one on ebay for like 5 bucks. I ordered 25 from tti.com for like $1.63
