Corrosion can also be removed from battery terminals and cable connectors with sandpaper or a specially designed tool.
These tools usually take the form of wire brushes that are very easy to use.
Its also extremely important for the battery connections to be tight.
The easiest way to check for a drain is to disconnect a battery cable and check for current flow.
If you use a multimeter for this purpose, its very important to use the highest possible amperage setting.
Doing otherwise runs the risk of blowing an expensive fuse inside your meter.
Some meters also include an inductive clamp that can check for current flow without disconnecting anything.
you might also check for a drain with a test light, which is less precise.
If the test light illuminates, then there is some throw in of drain present in the system.
In most cases, the only way to track down a parasitic drain is through a process of elimination.
