meepmeepmayer Posted August 10, 2017 Share Posted August 10, 2017 After my latest, quite demanding mountain ride (and planning more), I figured it would be a good time to check the insides of my 84V ACM. Aaaand there's some bit of heat damage on one of the motor connectors! Here's how it looks, if you have some input how severe it is (probably ok, but who knows) and if that connector needs to be redone, or what else is recommended, I'd be very grateful. Except for that one issue, everything is perfectly ok with no visible damages whatsoever. #1 Overview. You can see a bit of damage at the one motor connector covered partially by that heat sleeve. #2 Closer look. The discoloring on the sleeved cables is normal, that's just how they are colored. There is no visible damage anywhere, except for the one connector. #3-5: The sleeve is lightly stuck to the connector, and the connector itself is a bit heat-damaged. The other cables in the sleeve are totally fine. All the cables coming from the black motor sleeve are totally fine. #6-7: Cut out that part. Funnily enough, the inside looks less bad. #8-11: A closer look at the connector. The upper side (where the sleeve was) shows heat damage, the rest of the connector is ok (it looks much worse in those close-up, flash photos than it is). Well, guys, be careful on mountains If you have any input, specifically whether this is ok and can be left as is, or whether the connector should be redone... Is there some kind of high-temperature duct tape to reinforce certain parts, if necessary? How bad is this? Link to comment Share on other sites More sharing options...
