Default Re: OBC Bypassing

Your powerdrive would not have turned off with the relay in the charger bypassed. It needs the signal to the "Open" from the OBC, via the sense wire.

If your resistor is getting as hot as you describe, there is "draw" being pulled from somewhere and most likely is at the controller or motor. You are seeing voltage on both sides of the solenoid because the resistor allows a small amount of energy to flow through it to keep the capacitors in the controller charged and avoid a dead hit when you depress the pedal. Since yours is hot, you have higher than designed current flow being pulled through the resistor instead of the solenoid.

Default Re: OBC Bypassing

Thank you so much. I will be starting a new thread as recommended after I research a little more. I did bypass the charger relay but was monitoring the voltage signal coming back from the OBC to determine when the OBC determined it needed to "open" the relay. At 61.8 volts output and a continuous amp draw for 1.5 hour it was still charging. I am new to this but it seemed to me that the batteries were fully charged and were being overcharged.

And thank you for the insight as to the resistor. Once removed it reads 0.207 ohms. Unsure what it is supposed to read but undoubtedly more than that. :) I will look at the sponsors and order one up. And there is not voltage at both sides of the solenoid now. Goes to reason.

I did notice the capacitor discharge effect as voltage remains at the motor windings as it dwindles after releasing throttle.

Maybe I had the key on when charging? Or one of my limits is stuck?

All good info. Will look at all the posts in the diode/resistor section and get more educated, then start a new thread. Thanks so much.
