Motor testing question(s)
I am working on a 1978(I think) 36 volt EZ-GO resistor cart for a great old friend.
Numbers on the tag read 780313 149852. They were driving it back to the house after a long day of start/stop/bsing/start/stop ect...and it just quit. After reading this forum for a few days and lots of double checking I determined that something was wrong with the motor,so I took it apart and found the wire INSIDE the motor that goes to the F2 stud melted off of the stud. I'm pretty sure I can fix this but the question I have is... If I put my meter leads on the part where the brushes ride I am showing a dead short to the motor shaft itself and I dont think that is right? The motor is completely disassembled and sitting on a non-conductive bench Thanks for reading/responding,this place is great! |

If there is a lot of carbon dust from the brushes, that could be causing the short and a thorough cleaning might fix the short. |

Re: Motor testing question(s)
Thats what I thought.
I cleaned it pretty good last night and it got a little bit better but I think the insulation is breaking down it looks real bad and pieces are falling off/out. I think the best bet right now would be to look for a new/rebuilt one. Any suggestions? |

Re: Motor testing question(s)
Bump.
I have found many replacement motors with 19 splines,but am striking out on this one. Does anybody have any clue where I can find this style motor? Or can the coupler on the rear axle be changed to fit a newer style motor? many thanks. |
