There are so many different controllers to choose from. Where do I start?
Please have basic information such as motor type, voltage and current specifications, and vehicle weight, and we can assist you in choosing the proper electric vehicle controller.

When trying to pick out a Curtis Instruments motor controller for my application, I see the desired model has some missing numbers. For example: 1204-2XX. What does the "XX" stand for?
The "XX" is a designation number that tells us what options are configured on a certain electric vehicle controller. Some of these options could be certain error detection configurations, software differences, or even an exclusive controller for a certain customer. We have some internal documentation that helps us figure out which controller would best fit your needs.

I have a motor controller that failed. It is a 1244-4401. I have an extra one on my shelf, but the model states it is a 1244-4403. It looks exactly the same as the old one. Will this work?
This is a tough question to answer just by looking at the model number of the controller without any supporting information. More than likely this will NOT be a "drop-in" replacement. Usually there is enough of a difference in electric vehicle controllers, even though not externally apparent, that some type of error will occur. You need to contact Tecknowledgey, and we will be able to research this and find out if it is possible to replace one controller with another.

I would like to have a manual for the Curtis controller I have. Where can I obtain this?
Most Curtis manuals can be found on our web page at http://www.curtisinst.com/index.cfm?fuseaction=cDatasheets.dspHome.

My controller has a problem and I need to fix it. I have an electrical background and would like to fix it myself. Can I have the schematics for this controller along with any replacement components I would need to fix it?
Unfortunately, we cannot provide this type of information and product. The schematics for our products are proprietary and cannot be distributed outside of the OEM. This also applies to the components that are found inside our products. Please contact us at 914-739-4499 -- we do offer a repair service on selected electric vehicle controllers for a fee.
