Prestolite Electric IdlePro and IdlePro Extreme alternators now use Isolated Ground technology that's designed to protect engines from potentially severe electrolytic damage caused by stray voltage.
Isolated Ground technology helps to prevent overall associated component failure and vehicle downtime, according to Prestolite. It includes a dedicated cable that directs the electric current from the battery to the alternator and a second dedicated electrical cable that directs the electric current from the alternator back to the battery.
Common alternator designs allow the case of the alternator to be part of the electrical circuit. When an alternator is anchored to the engine electric current can then travel through or along the engine, increasing the opportunity for engine electrolysis or electronic noise interfering with other electronic equipment on the engine or vehicle. In today’s modern engines, the added electronic noise can trip ghost error codes – necessitating a service incident and diagnostic troubleshooting.
The Leece-Neville IdlePro and IdlePro Extreme high-efficiency/high-output alternators include Isolated Ground and an array of other exclusive technologies that help extend battery life and increase vehicle uptime by enhancing electrical system and engine performance. The company plans to add the feature to the Leece-Neville PowerPro and PowerPro Extreme series high-torque starters in the near future.
