Re: Runaway RXV
Glad you're alive. Anyone besides me think this cart is totaled?

Re: Runaway RXV
Is it just me, or is anyone else thinking about adding a positive cut off switch / emergency kill switch in line with the main solenoid control wire since the key switch is only an input to the controller on the RXV?

Talk about timing. I was considering a ground up build of a custom cart based upon an RXV frame and a custom body. For years, I've been building custom EV designs for others. Now that I'm retiring from that, it's long past time that I build one for myself. I'm thinking of using an LiFePO4 pack to cut weight. I have a machine shop and welding shop, might as well use it for myself once again. Quote:
Heck, a DPDT center off toggle switch could be used to combine both functions into one switch. Up for normal, center for total shutdown, and down for shutdown with no brakes applied. Essentually s more useful run/tow switch out in the open where it can be accessed while driving. Why hide it under the seat. LOL Bob |

Re: Runaway RXV
I see this as, one more reason to delay RXV ownership. Can we know the root cause?

Re: Runaway RXV
If either of you 2 guys do wire in one of these kill switches, will you please post the wiring diagram, of how you wired it in?
Sounds like a ton of people here , could benefit from that. |

Re: Runaway RXV
Maybe a large mushroom kill switch on the floor by the accelerator pedal. Possibly wire in series with an inertia fuel pump kill switch like on a car. At least this would prevent the run on your cart was doing after impact. You could easily find one at any junk yard cheap, or even ebay:

Re: Runaway RXV
If I were to do it on my personal cart I think would use the mounting hole for the optional foot horn switch, then connect it to a kill relay (NC relay) on the main solenoid control line. This would give me a foot activated button next to the brake pedal that would effectively lock the parking brake. (ideally only as long as it was pressed, although how reliably it would then dis-engage would depend on the controllers state since the logic level power for the controller does not run through the main solenoid)
Having said this I am not sure how happy an RXV controller would be with having the main solenoid control action being bypassed. |

Re: Runaway RXV
Not sure why shutting the key off wouldn't stop the vehicle... From what I can tell by the wiring diagrams the key is what powers the controller logic, if that is off then there is no command for the EM brake to be open so it should close by default thus braking the vehicle.

Re: Runaway RXV
Read the first post again. He did not turn off the key until after the crash. And it stopped then.
