A short in the turn signal wiring can cause the voltage gauge to fluctuate. A loose ground wire can also cause the gauge to fluctuate.
Probably a dying alternator. Other lights may come on or off in the dash cluster. Check your accessory bet and have your alternator tested.
No. As long as the signal is getting through, the gauge of the optical connection makes no difference.
Not Sure
An amplifier makes a (generally larger) copy of a signal or voltage. A rectifier allows current to pass in only one direction.
Resistance in the length of wire that makes up the extension cord causes voltage to drop. But it needn't be a problem with the right extension cord. For an electric drill, up to a 25 foot cord of 16 gauge wire will cause a voltage drop so small as to be negligible. For 50 feet, switch to a 14 gauge cord. For heavier power tools (circular saw in particular) you should use a 14 gauge extension from the get-go.
Remington makes a industrial 8 gauge kiln gun.
There are two different answers here: Older cars - an actual oil line from the engine came into the passenger compartment and was attached to a gauge that read "actual" oil pressure in the engine, so it was actual pressure that made the gauge go up and down. Newer cars - a special unit, called a "sender", is mounted on the engine to monitor engine oil pressure. This "sender" will allow more voltage to go through itself the more oil pressure it monitors. The less pressure it monitors the less voltage. The gauge goes up and down depending on the amount of voltage the "sender" is sending to the gauge.
The turn signal flasher is what makes the noise and lets the turn signal flash.
1999 subaru legacy wagon mph gauge works when it wants to what makes the gauge work? Is it a censor, fuse, wire please help
Your question makes no sense, please rephrase the question.
When I use the signal it makes lot of noise
Please ask your question again so it makes more sense . . .? :-)
