So you're saying a fixed resistance the motor will draw more current with a bigger controller just how much more and if I hook it directly the batteries will it draw even more

I don't understand how a controller can tell the motor is close to overheating doesn't seem possible, how does the controller even know the motor capabilities?

I think You can indirectly detect when a motor is getting hot by monitoring the field current.

In a Sepex motor, the field current is not dependent on RPM or load, but the resistance of the field coil can change as much as 100%b when hot.

Perhaps their software monitors for a certain percentage of decrease in field current for the same PWM to detect a hot motor.

Also since the resistance is changing on heating up the controller can sense the amount of current being drawn for a certain pulse width or at least a change

And just to be using the correct terminology. The correct term is inductance not resistance. Especially since we are talking pulse width and PWM.

I am pretty sure we are using the correct terminology, inductance does not change with temperature, only the resistance of the material does.

Also, PWM is a constant frequency, only the duty cycle changes, so it does not affect the inductance of the coil either.

Either way we are just guessing how the controller may be turning the LED ON to indicate a hot motor.

There is also an adapter that plugs into the wiring harness for each specific cart. Then there are inputs there for the 4 wherl drive option & the OTF programmer. I believe this is a Silverwolf controllerbut now manufactured by Madjax.

I got mine installed and love it, as far as cables, and solenoid did you change any of that out OHC123?

I guess the tolerances are close enough to consider it getting too hot hopefully on safe side but unless the programmer knows which motor it is being used on I'd assume the run configuration is also on the safe side of any motor rather than that specific motor, ie generic curves right?

Hey BakerM07,
I changed my cables to #4 gauge & i got an HD solenoid from Scotty B cartsunlimited.com.
I dont think you need an HD solenoid unless you plan on upgrading your motor. But surely the Cables. I plan on trying out a plumquick executioner.
