3 Wire ITS and Microswitch

#1

I have an 09 4wd Hunter with a Curtis 1296-5502 controller. I have replaced the controller 2 times in 6 months and it has stopped again. I am getting Fault Code 1-2 which is a throttle fault. I am checking all of the components. The manual for the controller shows pin 13 sending 15 volts to the ITS my R&T does not have a wire at pin 13. Power to the ITS on my cart from the parking brake switch and it is 48 volts. If anyone has any info on this please post. Thanks Heyward
