I have a 2006 Ranger TM, and I have what I believe is a defective Ignition interlock/ACS unit (part # 4010914 ). The starter will crank if I jump it, but it wont with the key. The ignition switch works as it should, and I have jumped the brake switch just to rule it out. This part is discontinued, and you can't buy it anywhere. What are my options to get this thing running again?
