Help!!!!!!!

My father is an old electrician and said it could be a cold soldier joint. He has a meter that I can check it with. I will beat this thing. I will post pics of the project when I'm finished.

I'm sorry for being vague, but when I said check ALL the connections I thought solder joints were included... I hope it's that simple!

This is kinda far-fetched but try twisting the wires at the sametime when running the system. I had similar problem with my bk controller. Found that parallel wire were badly soldered. It just cutted the powers when twisting at the right place..

Most likely a meter will not show a bad solder joint unless it is REALLY bad. Any resistance you see will probably be just the meter leads. Resistances that low are better measured with a conductance meter TBH.

Check the bullets, i got i cold solder joint in my mmm package NIB.

How did you catch the problem? Were you having similar issues?

Thanks,
Alex

Apply some "force" to the bullets and wire - should not crack/break...

Now within about 20 mins patricks going to be asking to QA stickers to bust someones balls... :)

Na, i plugged all the wires in to the MMM, and then I was going to yank them all out off the mamba(for a photo) when the wire came out, but the bullet didn´t, so i resoldered them all, just to be safe.

It never made it to the buggy before this, but i have had a friend with the same problem you described, so I resoldered all off his connectors between the ESC and motor and the problem was gone. So it´s definitely a case off only 2 out off three phases fireing.

I just home from school and dad meet me at the house with his meter and sure enough one of the wires would not carry a tone across. Resoldered that wire and everything worked like a champ. The just got home from school sounds funny. I'm the assistant principal of a local high school.

Thanks

Did the meter show any resistance? Just curious.

[AP Alex]

The setting that gave the tone read .011 for all the other wires and read .014 for this wire when I fixed it. He had another setting that he turned it to and all the good wires read 0 and this will still had some readin, but I did not pay attention to what. It was some sort of 70 series meter. He was an electrician/telephone man. The meter was used by him when he was a telephone repair man/ equipment installer. I'm sorry I did not pay closer attention. I was just happry I was not out a lot of money.
