Prestolite Isolated Ground Technology
Prestolite Electric recently pioneered the use of isolated ground technology – which protects engines from potentially severe electrolytic damage caused by stray voltage – in its line of IdlePro and IdlePro Extreme alternators.
The technology, which helps to prevent overall associated component failure and vehicle downtime, includes a dedicated cable that directs the electric current from the battery to the alternator, as well as a second dedicated electrical cable that directs the electric current from the alternator back to the battery.
More 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 in 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. www.prestolite.com
