I set a turn on voltage of around 13.8v and a turn off voltage of around 12.8v and it works on my bench power supply, but if I adjust the voltage slowly, I notice that I can make the relay continuously cycle if I hit just the right voltage. I'm not sure if this will happen when installed in the expo as the alternator voltage at idle was around 14v and battery resting voltage was around 12.8v, I'm hoping that the voltage will drop quickly enough when not running that it won't set at that quirky voltage load where it makes the relay go crazy. I couldn't really test the 1500rpm voltage at the battery by myself, but I know it should be over 14.5v but the idle voltage should be enough of a difference in the resting battery voltage.
Definitely don't want that 500a solenoid to be cycling that quickly.
