Project Tips

* A memory keeper is usually an electronic device that is powered with a nine (9) volt battery. If it's placed in the accessory socket, in the cabin compartment, the settings inside ROM memory of the computer are not lost. Without the aid of the memory keeper, your vehicle would have to be driven several miles for that computer to re-learn the programmed settings.

* Searching for multi-meter (DMM) is an electronic test instrument employed by technicians' and do-it-yourselfers to be able to electrical faults on the vehicle.

* To prevent sulphation, a battery maintainer should be used to make it charged when a vehicle is left out-of-service or when  in storage.


When working around a storage battery, safety glasses should be worn to protect the eyes from gasses and elecrolyte.
