Hey guys, just "finished" building my kit, and i have come across a minor failure on my voltage checks,
Terminal 4 -  -28mv
Terminal 18 -  -35mv

Could anyone chime in with some possibilities? been combing over the kits soldering and touching a few spots up to no avail, so i figured i would see if you guys could give me a hand.

Thanks in advance
Mike D.

Hello Mike,

Are you 100% sure that you have 28 and 35V, not more like 28 and 35mV? 

Some meters will adjust ranges automatically and just pop up a hard to see decimal point or other label that's easy to miss.

(Also, if you had 28-35V at those terminals, others would be way off)

Yeah, a few mV there is pretty normal (normally it is also a small negative voltage).  Depending on the impedance of the multimeter being used, it can be tough to even measure this sometimes.

Thanks for the confirmation CB! It was indeed in the -38mv range, surprised my meter even detected that since it isn't top quality by any means. Figured i would check around on the forums and see if i foobar'd anywhere along the build path. Just kinda surprised there wasn't anything in the manual mentioning that there could be the possibility that some voltage could be seen by some mm's.

Anyways, Thanks again CB! Appreciate it!
