Handle your ammeter to bonanza electrical problems draining effectiveness from your battery.
3. Remove the glassy bulb from under the hood, provided your vehicle is equipped with it. Accelerated the Timber and the motorcar doors besides. Brew positive all accessories are off. Acquisition the disagreement and restore the electrical manner in your vehicle with a infrequent tests you can perform Homewards.
Instructions
1. Pop your vehicle's hood direct and disconnect the ground (dusky) battery cable with a wrench.
2. Amuse your digital ammeter elsewhere of the toolbox. Connect the ammeter atramentous probe to the battery display you blameless disconnected and the blooming probe to the terminal of the battery cable.
In the Forenoon, you purchase at the end the trundle, turn the ignition indispensable to embers up your engine and all you invest in is a moaning sound or no sound at all. Electricity leakage or battery bleed can slowly discharge the battery in your vehicle after sitting in your driveway for a infrequent hours. A door that fails to shut tightly, an electrical short or a pathetic connexion may cache a flare bulb or an trappings on and gradually consume battery function.
4. Turn on your ammeter. The readout should register 0 amps, or approximately 10 mA (milliamps). Whether the readout registers above this figure, it is doable you acquire an abnormal bleed in the electrical course.
5. Challenge an assistant to remove the lustrous bulb from the Timber, lasting the Timber and then alter the light bulb. Do the same with the glove box light bulb. If removing one of these light bulbs causes the ammeter to read zero, that light bulb is staying on after closing the trunk lid or glove box. Make sure the trunk or glove box is closing tight by pushing on the light bulb switch, and then check the light bulb socket for a short.
6. Close the trunk and glove box tightly and make sure all accessories are turned off. Ask an assistant to pull a fuse from the fuse box from under the dashboard using fuse puller.
7. Read the display on your ammeter. If the meter readout remains the same, ask your assistant to replace the fuse and pull another fuse.
8. Repeat until the readout in your meter goes to 0 when your assistant pulls one of the fuses. The circuit that fuse protects is the source of the electrical leakage.
9. Check the wiring diagram for that circuit in the vehicle service manual for your particular vehicle make and model.

Or, if you prefer, take your vehicle to an automotive electrical shop and have them fix the problem.
10. Disconnect the electrical wires from the starter solenoid -- the small cylinder on top of the starter motor -- if none of the fuses that you removed from the fuse boxed caused your ammeter to read 0. If disconnecting the starter solenoid causes the ammeter to go to 0 amps, you have an electrical short in the solenoid or the wires connecting to the solenoid.
