Another newbie here (retired industrial electrician) trying to fix a mobility scooter for a friend. (retired machinist)
Scooter is a BladeZ DKS200 Sport, 24 volt. Basic machine, hand throttle control, squeeze lever right for forward, squeeze lever left for reverse, another pot w/knob to control max speed, only accessory is a small beeper. Looks like a well built machine.
Apparently they were discontinued a few years ago and no support is available. Have the operators manual but it doesn't say didley other than how to turn it on etc.
Web search for info, wiring diagram, schematic, etc came up blank. Did find a few posts a few years old, people looking for the same throttle pot.
The owner/friend had problem w/the throttle, would hesitate, go, not go, etc. He suspected the throttle pot, removed it and took the pot apart, saw carbon traces(?) on the pot so ordered a new one. Installed new pot and says it worked once and then quit.
Pot is 5K linear and checks out.
Number of the original pot (which he doesn't have anymore) is supposedly RVQ24YNO3-8A 21S B502 Cosmos
Replacement pot is a different brand.
Batteries (2X12volt) are fully charged. Motor and main controller are at the back under a cover.
I discovered that when throttle is pushed to full reverse there was a click near the drive that turned out to be the electric brake release operating.
The throttle lever only moves the pot a small amount from centre in either direction, (approximately 22º), so I removed the lever and found that when I turned the pot manually in either direction from centre the brake release would operate then the motor would start to turn, the more I turned the pot the faster the motor would go.
For full speed forward the pot had to be turned aprox 135º from centre. Reverse doesnt go as fast.
Dont understand why the original pot only had to turn a small amount to increase speed to max and on the replacement pot it has to turn a lot more, which cannot happen w/the throttle lever on.
Any suggestions or help would be greatly appreciated.
