2015 CC stutters
A mate of mine has a 2015 CC which is fully standard. The batteries are not perfect but he has been keeping the Save-a-Battery on them between ERIC charges and he says that they are showing a healthy charge.
When he's on the golf course after a few holes the CC will "stutter" under acceleration. By that I mean (his description) that it stops accelerating for a moment then starts again and does it a few times. At this stage I haven't driven it or taken any measurements but I thought I'd present the problem and get some opinions first. Any opinions as to why it would do that? |

Re: 2015 CC stutters
More than likely batteries but it could be an MCOR issue. You need to load the batteries when the cart is acting up. How old are they?

I agree that it is probably batteries but I wondered if anyone had seen this before as another problem. |

Re: 2015 CC stutters
In have and 90% if the time it’s batteries. Again you’ll need to load test them when the cart is acting up and find your culprit battery or batteries.

Re: 2015 CC stutters
Usually on a Sepex cart they do not shutter and shake as the a Series wound motor will. From his description that sounds like a Speed Sensor issue as he mentions "that it stops accelerating for a moment then starts again and does it a few times." Intermittent is common, but harder to pinpoint and/or test for as they will only fail the test when they are actually in fault status.
If his pedal position is not changing when this surge is occurring, then that more accurately pinpoints a speed sensor issue. Usually a battery issue gets worse and not better. Definitely check the pack, too. This could be an anomaly or.....? |

Re: 2015 CC stutters
When I hear someone say “stuttering” I’m thinking of the cart “bucking” and 9 times out of 10 that’s a battery issue. Anything is possible but if it’s “bucking” then you know it’s usually battery related.

Re: 2015 CC stutters
I agree and that is prominent in Series carts. By the description the OP gave Yawood, it sounds different than the that and coupled with this being a Sepex cart. Intermittent speed sensors will do exactly what he described. That does not mean it is the issue, but is a factor in its assessment.

Re: 2015 CC stutters
Thanks everyone. The cart doesn't "buck" as such just dies for a moment then picks up again only to die again and pick up again.
I'll start taking some measurements soon but I wanted some expert knowledge to know if there was anything likely other than batteries. Nole, where is the speed sensor you speak of and is there a way of testing it? p.s. His pedal position is not changing as it occurs. |
