well its fixed. ghetto rigged but it works. it was the stim. I guess it never came with a socket for a wall plug in (me and my friend both thought it was optional) but I got to looking at the "wires" for the ground and relised they go nowhere, the "optional" socket thats missing in the pic completes ...

ok, i resoldered the stim and have the same results. I also checked using ohms, getting no reading for grounds.

Ill try and find my digi camera and take a few pics of it along with the ms board.

this is a kit im attempting to assemble.

I tested all the pins on the ms for ground with the stim attached but without the extra ground wire going to the regulator(tested pins on the bottom of the board). Then I tested the pins on just the stim, the results I just posted.

correct, none of them ...

alright, tested all the db37 pins on the stim.

none of them ...

trakkies - after the last test, will your test still help? and yes the d9 is installed the correct way.



I will check the stim to make sure im getting ground to the db37 on that.

im half tempted to buy another board and start over

thanks guys,
Alex

ok, I just checked all the db37 pins and I have no ground... I ran a wire directly to the battery then to the center pin of the regulator.

new readings from the regulator from left to right:
8.82v, ground, 4.97v

on the 40 pin socket:
1- 4.97v
2- ground
16- 8.84v
17- 3.31v
19- ground
20- 4.97v
31 ...

ok, battery tested at 9.64v before and after testing. With the regulator in, ground on the center pin going the pin 1 on the db37. from left to right on the regulator:

9.26v, 7.51v, 7.48v



thanks,
Alex

so put a ground wire directly to the center hole of the regulator in u5 from the db37? any particular place on the db37? with or without the regulator?

sorry just wanna be sure


thanks,
Alex

ok, its reading at .001

ok battery is testing at 9.2v, testing from left to right where the regulator goes without the regulator:
8.9v, 1.8v-1.3v, 1.8v-1.3v (5v side, on the right)

on the middle and right side, it started at 1.8v and slowly went down to 1.3v, battery still tested at 9.2v


thanks,
Alex

just tested them, getting infenite resistance(like im not touching anything)

thanks,
Alex

Ok, I have ms2 v3 and im using a friends 2.21 stim he built but never used. Im testing the power supply, using a 9v battery. on pins 1, 2, 19, 20, 31, and 32 I an getting 7.5 volts on the 40 pin socket. no grounds on the socket. I have to use the ground off the battery terminal on the stim. I also ...
