Hi all,
I have a 70A 24V Rhino controller that I tried to put into my kids
Gaucho jeep. Mainly to replace the switches that were there to
turn on the motors and to reverse.
Turns out the Rhino controller is programmed for a wig-wag throttle,
meaning 0kOhm - full backwards, 2.5kOhm neutral, 5kOhm full speed
forward. The controller also has many safety features that e.g. prevent
one to turn it on with the throttle full open. I have no wig-wag
throttle that would fit into the jeep and also would like to keep the
separate gear stick that activates a switch for reverse. The controller
has a nice ramp-up so going to full speed right away would be much
smoother than before. Hence I thought I could just use two 2.5KOhm
resistors to simulate the throttle pot and have one switch for forward
and another for reverse. Unfortunately the controller is smarter than me
and wont let me do it with switches.
I was hoping somebody might have a pointer to a simple and cheap circuit
that would let me simulate a wig-wag pot to the controller with two
switches. I.e. S1 being drive, S1 being reverse
S1 open - 2.5kOhm
S1 closed, S2 open - 5kOhm
S1 closed, S2 closed - 0kOhm
I tried this with a pot and simply shorted two legs together to simulate
S1 and/or S2 but the controller must sense this immediate short and goes
into failure mode. I suspect i need a gradual change.
Any thoughts?
Btw, reprogramming is not an option as a programmer tool is needed and
shipping it would be cost prohibitive, I dont want to invest a fortune
into the jeep, just thought an electronic controller would be better
than the stupid switches that are way overloaded and dont take the dirt
and sand well. Now that stupid controller is smarter than me. Darn.
