When i rev my car up the charging light comes on for a split seconde when my lights are on my turn signals dont work and some times the lights will go dim when that happens i got to charge battry or j

First charge your batery and re- install it in the car. Turn on the ignition and with a multin tester check for voltage at the battery. It should read between 12 and 13 Volts DC. Start the engine, accelerate up to 2500 rpm and measure voltage. It should read between 13.5 and 14.5 Volts DC.

If the voltage at the battery is lower with the engine turned off, your batery might be bad.
If the voltage with the engine running is not between 13.5 and 14.5 volts, your alternator is bad.

Battery keeps running down on 96 cadillac elderado

if battery keeps running down. check the voltage across the batery posts while car is off.should be around 12.5 to13 volts. then with tester hooked up to battery, start the car. if alternator is ok, it while read about 14 volts give or take a few volts. if the gharging is low its a bad alternator or the drive belt.

I just bought a punch 500 a2 amp. i hook up my ground, then try to hook up the power cable and it sparks. my punch 250 was hooked up minutes prior to this so i know my wiring is good. what the heck is the...

The spark could be from the capacitors in the amplifier charging. Make sure the main fuse from your battery is still good and also check all the fuses on the amplifier. Verify all the wiring is correct and make sure none of the wires from inside the positive cable are poking out and touching the vehicle or amplifier chassis. If you have a 1k ohm resistor, you can put it in series with the amplifier power line to slowly charge the capacitors. You can do that by following the directions from the link below. After doing all that, remove the 1k resistor, hook it all up and try it again. If it still doesn't work, make sure your remote wire coming from the head unit has a voltage on it when the head unit is on. You can get a cheap volt meter from a hardware store or wal-mart.

I have a model 5251 generator that was not charging the battery. Now the motor will not start.

either a)there is no battery charger installed, or b)the battery charger is installed incorrectly, or not hooked up at all. the third possibility would be that the charger itself is not operating correctly but in my experience that is seldom the case.

the charger uses source voltage from the utility to charge the battery between tests and usage. the generator does NOT charge the battery during operation, so a trickle charger that uses source voltage must be installed in order to keep the battery charged. this tends to slightly decrease battery life.

reconditioning the battery prior to re-installation after the charger has been sorted out is recommended, but a new battery may still be needed at this point.

What a i supposed to charge the capacitor with?

yes you should. hook everything up and before you put the fuse into the amp circuit by the battery place a light bulb or test light to join the two endstill the light shuts off. once it is off the cap is charged, now install the fuse

My insignia amp wont work

Try removing the capacitor and discharging it with a .5 watt (radio shack) light bulb, and then reconnecting it in the same fashion.(before hooking it back up to the amp place it in line with the capacitor until the cap reads 12v with a multimeter or capacitor display) The capacitor will conduct but not store a charge for the amp if not properly charged before making the amp/capacitor conection. and therefore shut down or not start at all.
