View Full Version : Whoa! What was that?

So I reconfigured my setup on my motorcycle. Nothing major really. I essentially just reversed the compartments that I was going to put the batteries in, and the compartment that I was going to put the controller/contactor. No worries right?

Wrong.

I fired up my circuitry after cleaning up my cables to make sure that they were somewhat orderly. Precharge worked o.k..... contactor closed.... I twist the throttle...

and NOTHING.

I unplug the electricity so I can look at it. I take an ohm meter to the 0-5k ports of the Curtis controller... 6.83 ohms without twisting the throttle.

Come again?

I twist the throttle.. 6.83 ohms. I am guessing high pedal disable stopped the motor from spinning.

O.k., something's messed up... so I take the throttle off entirely and twist it. 0-5.31 ohms.

I put it back on the controller and test it again. 0-2.86 ohms.

I put everything back the way it was now.

Worked fine. No worries.

What just happened? It's like my controller had a mental breakdown for a second. I test it another three times. Everything's fine. But for a second, it wasn't responding to throttle. I am guessing the time that it read 0-2.86 across the controller had to do with some internal resistance. I can deal with that.

But it didn't work at all the first time, unresponsive to throttle and read nearly 7 ohms. That's just weird.

Am I missing something? Or is it because I shouldn't work on EVs when I am having an off day? Sometimes as I am beginning to learn, stuff just leaves a guy scratching his head. Never happens again.

Weird.

That is a weird one. Maybe it wanted a day off too?

I have had a few High petal issues what the ZAP Curtis throttle. I wonder if this is a Curtis type issue?

I'm guessing. I mean, that was just strange.

It was a Curtis controller... and it hasn't happened since. Probably some wire just not making contact somewhere or another.

Either that... or my EV is HAUNTED.
