If anyone knows or has a Crystalyte controller and 4 pin throttle (the ones with the LEDs on them), can you tell me how they're wired?

Is the male or female connector on the controller?

What's the pin order for:
Battery +
Ground
Hall Signal
5V +

Which wire colors are which?

Does it match this?

Any help would be much appreciated.
 
Over at Ebikes-ca there is a pic of a controller, no telling how old, that shows the following colors. There may be other pinouts shown on the site, if you hunt the whole thing.

Red ----5v
Yellow--ground
Green--throttle signal

And the other one would be the 4th wire, 36v or 48v battery indicator. Leave it disconnected if you ride in the rain a lot.
 
Hi Voice,
I have the old c lyte throttle with the LED, this is from maybe 2004. It is a four pin Throttle. I no longer have the controller,
but I have notes from when I changed things and here is what I have. Some is my own notes and other info I got here from post by Rkiosik, rick, and others, and there is a thread on wire colors matching , called "Known to work" controller wire combinations, something like that.

******DISCLAIMER***

I do not know much about this stuff I am a experimenter... I have stolen this info from others and can not say it will work for'
sure. Below someone notes that wrong wire combination can ruin your controller so use caution with This information.

throttle Controller
RED__________RED

Black-----Yellow

WHITE------WHITE

Purple ----ORANGE (Wait this pin is dangerous please note)

Throttle colors controller-- WE lyte(The Wilderness Energy uses the same 4 pin flat black plastic connector that Crystalyte uses and has the same pinout.) this info from ES somewhere

The throttle wires as shown are
Red= +5v
Black= ground
White= signal


that pin 4 is the dangerous one. it carries the full battery voltage for the fuel gauge or voltmeter built into some of the throttles. it is dangerous because if you are trying to wing it and connect the throttle by trying varoius wire combinations you could permanently damage either the controller or the throttle by connecting this wire someplace where it should not go.

the pin numbers are embossed on the connector right beside where the wires go into it. you may need a magnifying glass to see them.

another way to get the pins on the controller side (female connector) is to look at it with the wires pointing away from you and so that the exposed metal contactsare facing you. pin1 - +5 will be on the right and pin4 (the dangerous one will be on the left)

you can also test to see which one it is on the controller end using a voltmeter. connect the voltmeter black wire to the battery - terminal. probe the terminal on the left. it should show the full battery voltage. the one on the right will show only 5V.

as far as generic throttles go the only way to tell is to either look for documentation or to take it apart and see how the hall sensor is connected.

Hope that helps

I have attached Crystalyte wire diagram commonly used by most vendors. Please be aware that ebikes.ca use 3 pin throttle wire on most of their controller, they dropped the last pin which is use for voltage.
View attachment Crystalyte-Controller-Wire-Diagram.pdf
Also BMC throttle connection are differ, they move ground from pin 2 location, to pin 3. I also attached BMC conversion wire diagram. So DO NOT use BMC throttle as your Crytalyte throttle reference.

I hope this will help.
