I just installed my ADD Chase Rack (C115802800103 F-Series Race series) I got from Amazon and the actuator burned out already. All the wiring was done to the ADD instructions and I did not hold the motor on for extended periods of time. Checked the switch and got 12 volts checked the wiring on the actuator and got 12 volts. Even did a direct connect and no sound on the actuator. I honestly love this rack but can't belive a three thousand dollar rack would have a crappy actuator so dissapointed but hopefully Amazon will be able to have ADD send me a new actuator because I honestly love it and don't want to have to Uninstall it all just to return and exchange. OK rant over but seriously I thought ADD was high quality and I saved so long to be disappointed. I know I should have gone through ADD instead of Amazon but Amazon had it in stock and ADD is weeks of wait time. My impatience burned me once again.
