Check the listing for details. 8984 MSD Starter Saver with Signal Stabilizer. Condition: New, Made in US. Listed at 212.95 USD. Start Retard to make for Easier Starts on Crank Triggered Engines. The Starter Saver receives the trigger signal through an MSD Crank Trigger Pick-Up or the Distributor's magnetic pick-up. This Control has a very accurate pick-up compensation circuit resulting in rock steady timing throughout the entire rpm range of your engine. There is also an LED that illuminates with each trigger signal to confirm operation and the circuitry is completely potted in a polyurethane compound for extreme vibration resistance. When you install a crank trigger system, having locked out timing may put a strain on the starter and flywheel. This compact controller provides a retard that automatically retards the timing during cranking to ease the pressure. The MSD Starter Saver measures only 1.5" X 3.5" X 2".
