Hey guys,
I've got a bit of a strange CA problem.
I build a kit for a guy a while ago and all was well until he cooked the HT3525 going up a hill at 5km/hr with a heavy load on board.
The motor was replaced with another but ever since the CA has been doing strange things - the voltage overreads by 0.8v which isn't alot but it's noticabley too high when you see the full charge on a lipo pack. I tested it back to back with 2 other new CAs and and a multimeter and they all read the same (correct) voltage.
I could live with that (the guy didn't even notice) - the main issue is the speed is out of whack, it jumps around all over the place and is reading way too high, causing the bike to promptly cut out as soon as you start accelerating. All the settings were as they should be, and the same as another CA I tested which worked fine.
The problem is he's in another state so I can't test it all on the bike.
So I got him to send the CA and his controller to me, both of which functioned fine when I bench tested them (aside from the voltage over-read).
I tested his CA on 2 different controllers (his and one of mine) and it worked fine.
I tested his controller on a new motor with my CA and his and both read the same.
So the only other thing I haven't tested is his motor (which I can't due to being interstate). The voltage over-reading aside, the speedo being whack has to be a hall signal issue right ? All I can think is it's not getting the hall signal correctly from this new motor, but the motor itself functions fine (with the CA disconnected) - so the controller is seeing a proper hall signal.
Any thoughts ? I'm stumped!
