I do have a very weird issue with my TSDZ2 project.
Before, i had succesfully ran with a 14S setup, using the ESP32 kit from MSpider65, and have had quite some fun with it. This (offcourse, as expected) ruined my plastic gear, but this wasn't an issue, as I quickly managed to replace it with the Brass variant.
But, after putting in the brass gear and reassembling everything i've seen some strange electrical issues, shorts/sparks in the controller, replaced the controller with a new one (that's #2), double-checked all wiring and assembled again. Mind you, this controller was already 'modified' by me from new, to be working with the ESP32 wiring.
Again, some sparks going around, but i had already installed a fuse now between controller and battery, that fuse jumped out quite quickly.
To be safe, i then ordered a new motor (that's also #2), and installed it, unfortunately i still did see issues with short circuits and other strange behaviour.
To be sure and go all the way, I then ordered a new motor AND new controller (that's #3 for both!), with the plan to install them 'as default' and get the TSDZ2 running 'as should be from factory' first. This should give a good, fresh base-line to get going from again first.
This controller and motor have come in, and i've installed them. I've drained my battery to as far as 54.49v (it's a 14S / 52V battery), then for the first time switched on the battery, switched on the controller and it looks fine.
Only problem; It gives a E02 error, not sure why this happens.
Well, in a try to get rid of the E02, i then uploaded the OSF firmware, and with the JAVA configurator set the battery to be 14 cells large.
Uploaded the firmware, and tried the working of it.
Although i did get some E04 error at first, it seemed to be working on the next try anyway.
I'm not 100% sure if did get some 'assistance' from the motor but i'm quite sure it did (i tested it with my bike hanging from the ceiling). This also caused my small 5A fuse to burn out cause the motor offcourse draws more than 5A when giving proper assistance. I've introduced this fuse just as a extra safety-margin to prevent major currents going over the motor or controller in case of any further short circuits etc.
So far so good, let's put in a bit larger fuse (10A this time) and see if we can get the motor to be running again.
Put in the fuse, turned on the battery, then turned on the display (VLCD5), and after a few seconds (without further touching the bike), bam! fuse is out.
Now, everytime I put in a new fuse, it burns out immediately (with a bang!) a few seconds after turning on the display.
I don't see short-circuit (continuity between my main-power-in leads (with battery disconnected offcourse) all the time, altough sometimes i do see continuity with roughly 470 Ohm resistance in between. When I then back-roll my wheel, which moves the motor slowly, it seems to dissapear into no-continuity.
I'm not sure at all what to do now and what else could cause these issues. Basically i've replaced the motor and controller two times already, the last time being both together at same time.
I'm still able to program the controller by the way, as long as i don't turn on the display.
Hoping anyone here can help me out on how to get this issue captured, maybe anything to get started with checking/measuring, etc.
Thanks a very, very lot in advance!
