I have a Razor MX650 with a 6 pin throttle (five wires). There are two black wires. I assume they don't carry current and I put the black multimeter lead on one of them. The third wire said 4.5V regardless of the throttle position. The fourth wire fluctuated from 0.8V to 3.3V as I turn the throttle. The fifth wire showed 39V.
Does this throttle need to be replaced since it only goes to 3.3V at full throttle, or is there some kind of built-in limiter that keeps it from reaching 4.5V?
We sell MX650 throttles on our Razor MX650 Parts page.
