Hi,I've got 3 very similar Koford 15a motors and 2 of them feel very weak when you turn them over yet they were supposed to have been zapped and freshened up while the 3rd hasnt.The 2 have been gone through and there is absolutely nothing to suggest otherwise except for how they feel when I turn them over.I was quite impressed when I first saw them and dont think for a min that there was any shady stuff going on so to speak but there may have been a mistake during zapping the mags.Or I'm just missing something because its been a long time since I've built a motor.
Why would the mags feel weaker and have less of a indent when you turn the motor over?
To make things even more confusing the ones that feel weaker are noticeably stronger if you put something metal near the can on the backside.They literally jump off the table at a screw driver the same distance as a lighter fresh cobalt motor when the unzapped mags just sit there.
Am I missing something?Is there a reason why the fresh motors have less thump to them?Or is a tear down in order?
Thanks
