Issue with vv board

[ruff]

Sorry to hear that zig, it is mind boggling if everything is as should be it should work, what readings do you get if you test the wires that run to the battery connector before it goes to the connector, like where they connect to the board? I had a loose wire to the center pin on my 510 connector and that gave me issues for a bit, if the conector is loose in the box I've managed to twist the wires off of the connector.

If I understand write you asking about the positive wire that goes to the 510 connector and the ground that goes to the connector as well those read 8.08. The battery terminals read 4.04v a piece but if I touch the inside of the connector positive an the out side negative and test I either get 7.4v constant,1.4 pressing the button or I get nothing. Nothing has ever beatin me this bad (a machine that is)

Just read on my meter that touching the outside of the connector and the positive I get -.01v to the connector...THIS IS NERVE WRECKING lol

Yeah the wires running to the 510 connector, so even there you have the same issues... How frustrating lol, it seems to me that the issue is going to be the regulator or pot since you are getting juice up to the connector.

Have you tried a continuity test from the outside of the connector to the center pin just to be sure you dont have a short in the connector ?

I startin to think its the pot if I touch my positive to the power in then touch the middle pin on the pot I SOMETIMES get 7.4-8v other times I get 1.4 turning it up makes it read 7.4 if I turn it down it won't read the correct voltage only 7.4 all the way up and 1.4-8 all the way down I'm going to remove it this time and see if anything changes

yeah, i know that feeling, ive got 3 drawers dedicated to stuff that has gotten the best of me, so i use those things for spare parts for something else lol ive still got my first 2 auto batts and pcc around here in pieces, damn regular ce2 cracked and leaked all the juice into the pcc shorting it out, and the auto batts suffered from "over filling" and the juice drained into the auto switch... so now i have a couple spare parts and pieces to play with at another time lol

Update!!!! Ok it's working!!!! Kinda... It's backwards the pot has to be the culprit it reads 6.8 turned down and 3.4 turned up..... I re soldered the joints to the pot so that's working as well as the regulator..kinda now next issue I'm getting power to the connector of course because I'm testing the volts but my damn cart won't fire!! Lol easy fix I hope

good to hear, now as for cart not firing.... the center pin may not be contacting the center pin on the cart fully.. i had to adjust a few of my carts to get this to work, i just used a precision flat screw drive and pried up on one side lightly and then switched to the opposite side and did the same, trying to get it as even as possible, it may cause your cart to not fully seat in the connector but its worth a try and if that fixes it you could pry the center pin of the battery connector up a bit on each side to try and compensate instead of doing it to your carts

Better news!! Getting correct numbers in the right direction now ruff oh we're right it was the regulator for some reason I decided to grab the back of it and press it against the board and now it reads perfect still getting power to the connector up to 7.6 all the way down to 1.8 and everywhere in between but my carts arent firing center pin is raised were it should... Hmmmmm

cool... do your carts fire on any other pv ? ill assume that they do... have you tried turning up the juice a bit to see if it causes them to fire? if you are running atties ive noticed mine wont fire if i have loaded them too full of liquid

 

[TheZig]

It just wasn't screwed on tight enough and it fired at 4.6v then as I was putting it together my damn switch wire broke from the board.......great...now my board is all burned up from me trying to reinsert the wire then i was holding to tight and i lifted the regulator off the board grrrrr haha but at least I know it all works! So now all I gotta do is some re soldering and I'll be good to go

good to hear ive actually got my + wire from the batteries soldered to the back of the board so i didnt have to fool with trying to put it back in the hole
