It has been some time since I first started having a serious problem with my e-motor system on my trike … about sic months now. Whenever I would apply power to the motor using the hand throttle the power would shut off just like I turned it off at the switch on the battery. Then I would have to wait for it to “reboot” only to keep having it go back off most of the time. Once in awhile it would remain on and I could actually use it. I contacted Grin Technologies where I bought it asking them what they thought the problem might be. They said that it most likely is the battery but I have 3 batteries and it does this with all 3 and one battery was brand new at the time. Then they said that it is probably a bad wiring connection. I went thru everything and found nothing wrong. That was the end of their help. They were at least on the right track. The problem had to do with the battery power being interupted. All the time I was suspicious of the controller. Replacing the controller is not inexpensive so I did not jump on it. It use to cost $130 plus shipping but now it is $160 plus shipping. It was like gambling since I did not know for sure that the problem was the controller. Recently I took the plunge and ordered it from Grin Technologies. It only took less than two days to receive it … amazingly quick … about 24 hours from the time they shipped it. I installed it the same morning I received it and went for a ride. The gamble paid off. It works great once again. I sure wish I would have played my hunch much sooner. Anyway, I am rejoicing as I have a properly working motor back again. I have turned to Grin Technologies a few different times previously for technical help and never once did they actually help me. If I can figure this out knowing next to nothing about electronics I would think they should be able to be of help. Oh well, with this working right now I can …
KEEP ON TRIKIN’
A FREE GIFT awaits you!
BTW, I want to give credit where it is due. I received an email from Grin Technologies offering to see if they could repair my old controller and have it covered under warranty. It appears that the battery power has an issue somewhere inside of the controller. I would, of course, have to return the new controller I just bought. I truly appreciate their offer but there exists two issues. One, I would have to be without my motor for quite some time. I would not care to do that. And two, I doubt if I could return the new controller as I had to modify it to hook the battery power up to it. Oh, and another thing to their credit. I selected and paid for the least expensive shipping when I purchased the new controller but I received it super quick meaning that they must have shipped it the most expensive way … overnight. That was really nice of them.
