Generator went out/capacitor.

[Mertz]

My generator was charging fine until today when all of a sudden it started making noise and doesn’t show a charge on the gauge. It could just be the brushes but the sound is more like a bearing. When looking for a replacement I noticed some have a capacitor connected to one terminal and a screw to the body. Mine doesn’t have one. Should I add one and what does it do?  Could this have caused a failure? I just hooked up my headlights so it was getting a little more draw when I had them on.

Capacitor on a generator is just to cut a generator whining noise on a radio.

 

Will  not affect charging as I understand.

It did have a radio and an antenna but only the antenna remained. So the capacitor probably had no effect on the electrical system.

Took the generator off and spun it with my drill and I got up to 7.5v. The bushings look ok but the bearing was catching now and then especially if I spun it in reverse. Took the cover off and removed the bearing. It had a lot of dirt in it. I cleaned it and it spins better but rattles a bit. I will be replacing it. Will a sealed bearing work with the race still in the generator? Is that removable? Will any bearing for any generator work? Mine is a Chrysler Autolite.

bearing can be bought by application and or physical dimension and type of seals integral to the unit

for the drive end of the generator use a sealed bearing.  That is the only way you will recive one back from a rebuilder.  You could have a bad commutator pitted at the copper plates edges that will make a noise.  It is not recommended to spin a generator backwards as the brushes can bite into the armature.  They are tapered to spin one way and wear in. I recently did an article on our dodge truck site 39-47dodgetruck on Io there is a part number for a bearing that will likely fit. Bob Harrison

I tried getting to the site but all I get are access to ads. Can you give me the part number.

   The stock forward generator bearing is 602454. A 6203 has the same dimensions, 17x40x12mm. I believe that a 6203-2RS is the sealed bearing that you would use.
