I have a ‘99 F250 SD, 4×4, Triton V10 with a Viper Car Alarm, model #550HF. The starter won’t turn and I get no clicks from the solenoid. I have reset the Car Alarm using the valet button, and have found that there are 12 volts at the solenoid when I turn the ignition to crank. And, when I short across the solenoid I get clicks.I understand that the alarm has a starter inhibitor, but figure that with juice going to the solenoid it should crank. Shoudl I replace the solenoid? The truck is under warranty (but not the alarm), but I would need to tow it and I want to be sure that the alarm is not the problem. Can anyone help me?
