ParCar scraping noise

[UpNorth]

Bought a used '07 ParCar a few months ago. Runs fine, new batteries, but I'm wondering if the slight "scraping" noise that takes place when I take my foot off the accelerator means anything. Sounds like it's coming from the motor or transmission area. Not a problem right now, but I'm wondering if this is "normal" or not. Is this some sort of "regeneration" brush system designed to recharge the batteries during de-acceleration?

Scraping is not normal. That area of the cart could be axel bearing, input shaft bearing or packing or motor bearing. Do not go to long without having it checked.

[Frank7]

Still do no like scraping, not normal.

I think this cart has a regenerative braking system - when you let off the accelerator, some brushes engage and it puts some energy back into the batteries. Correct? If so, this is what I think I'm hearing. Probably "normal". Since I haven't experienced this type of system before, it may be what I'm hearing. It only happened when I take my foot off the accelerator and coast to a stop.

[Frank7]

The motor has regenerative qualities and ALL the brushes are in action after the accelerator
Is released. The motor at that point turns into a mild generator and sends voltage back two red the batteries.
This action should NOT produce a scraping sound unless the four unit large brush assembly is worn or loose. I believe it is worth checking into.

[UpNorth]

Should there be ANY sound at all? Perhaps I am being too critical of what I am hearing. Is it normal to hear SOMETHING back there that is different when you take your foot off the accelerator and slow down?

My ParCar has a pulsing scraping sound when you let up on the gas or apply the brake. After almost five years of this I hardly notice it anymore. I have serviced annually and for two weeks it is quiet.

[Frank7]

Perhaps you are, the decelleration has a different sound than accelleration but iI sill would not call it scapping.
Ask anouther Par Car owner at the square to ride yours and come to a conclusion after compairing.

[UpNorth]

Thanks, Frank. I've never noticed this type of sound with other electric carts before (Club Car, EZ Go, etc), but perhaps they don't have a regenerative system. I'll have to compare it with another ParCar to know if this is "normal" or not.

I had the same scraping noise when I took my foot off the gas, I had PAR CAR pick up my cart and they had to change some bearings. I agree with Franks first answer - have the bearings checked

[JoMar]

Scraping noise can never be good....I agree with Ron and Frank....get it checked quickly and by Par Car......you know it will only break down on a dark, rainy night when you not close to anything.
