What is cunstruction of tempratuer sending unit.
the current in the drain circuit of a field effect transistor.
I read elsewhere on the web that 25 milliamps is typical , and over 100 ma indicates there is a problem -- perhaps a stuck switch or partial short.
Yes. If the alternator is dead and you drive the vehicle, all the power is coming from the battery and it will eventually drain completely. Also, if a diode is shorted inside the alternator, that can drain a battery.
If you are going to store your vehicle for a long period of time it is a good idea to remove the battery to avoid battery drain.
Electrical drain on battery
Because if you reversed the polarity at the battery it would blow the fuse through which current flows to the drain.
Dead cell in battery, a light is on somewhere on the vehicle, or a relay is stuck.
If the donor vehicle is running and has a properly functioning alternator, no.
No. The power to illuminate the Daytime Running Lights (DRL's) is supplied by the alternator, and does not have to be supplied by the battery. Once a vehicle is started and the engine is running you could remove the battery from the car entirely and everything requiring current would still operate.
No, you Ipod does not use any of the vehicles electricity, it runs on it's own battery. The only way it can have any effect on the vehicle's battery is if you have a USB port in your vehicle and are charging your Ipod. In most cases the amount of energy needed to fully charge an Ipod is not enough to drain the battery to empty.
Doesn't work like that. Current drain is dependent on the (internal resistance of the battery and the) resistance/power requirements of what's connected to the battery. If shorted out, the current - unless the battery is fused or otherwise protected - can go into tens of amps.
Something is on drawing power. Can be any light on the vehicle or a relay stuck.
