Inverter beeps when I plug in extension cord. Nothing else

The battery is brand new and reads 13.5 at engine off and nearly 15 volts at engine idle. I do not run the inverter without the engine running. Alternator is rated at 80 amps

It is possible the alternator's power is higher than that of the inverter ,that is overload

I have a 1985 Kawasaki vulcan I put a new stator in rode a couple days now battery wont charge. Try to start and nothing barely a click from starter

Buy a "multimeter" (about $10) and switch it to DC volts.
Fully charge the battery.
Hook leads to the battery (red to positive, black to negative).
Start engine, and check meter.
You should be pulling about 13-14 volts DC.
If not, unplug output wires on the voltage regulator and hook the leads to it.
Start engine, and again, at idle you should be getting about 13-14 volts DC.
If not, unplug alternator (stator and rotor) and hook meter leads to wires, AND SWITCH TO AC VOLTS on the meter.
Start bike, and at idle you should be pulling 15-20 volts or more, with it rising (sometimes drastically) when you rev the engine.
This will tell you if the alternator's bad, or the regulator.
Also, you said you changed the stator, but sometimes the rotor becomes de-magnitized, especially if you've dropped it.

I have a 01 flht the has a problem with the voltage or charging system the bike volt gauge sits around 11 volts at idle but when driving the bike around 2 thousand rpm the volt gauge reads at 14 volts the...

Sounds close.

The faster the engine's RPMs, the faster the alternator spins, causing the voltage to increase.
The voltage regulator (as the name implies), regulates the voltage coming from the alternator, and going into the electrical system.
Factory instrument gauges are not alway accurate, and more so just gives you a rough idea of what is going on.
A better test is to get a DC voltmeter, and connect to the battery terminals and see what's going on.
At idle, should be about 11-12-13 volts.
When the engine is reved, it should never go above 14-15 volts.

New battery keeps dying in brand new ninja after a day of short riding

Sounds like the charging system isn't doing it's job.

Get a voltmeter across the battery terminals (red to +, black to -).
Start engine, take readings at idle and while revving.

Should read between 13-14 volts.

2003 freightliner mt45 battery indicator stays on.

Put a volt meter across the battery and if it reads less than 13 volts then it has a problem. The system should be 13.5-14.5dc..... 15 volt max. If it reads low only that idle, the engine may be idling to low, the regulator is bad, the belt is slipping, or the system has to great a load on it while idling(to many lights and electronics). If it comes up over 13.5volts when the engine is revved up then the regulator/slipping belt/ or load is most likely the problem. If it does not come up to the voltages listed above then the regulator/alternator are faulty.

New altenator and battery reads 12.7 volts. The light came on when I did have altenator problems. I replaced the altenator and idle the battery reads 12. 7 vp;ts and when the engine is running I see near...

because this fail es record on memory, and is for remembering you the low charge of 12.7, at all time from the motor is on; the batery has to carge from 13.5 v to 15 v,
did you see the band is tight and not very loose.
if that es correct, you should visit the electrical work shop...

I'm concerned about having the proper extension cord. Just bought 15' light duty outdoor cord with 2 prong plug-SJOW/ 13 amps/ 25 volts/ 1625 watts. Is this sufficient for the # 20070910...

There should be a plate on the smoker that tells you how many amps/volts/watts it uses. If the values are lower than your extension cord I would try it, however make sure you feel the cord after the unit has been on for a bit, if it feels warm or hot to the touch, I would discontinue use of the extension cord.

If you are in need of a user manual you can find a downloadable (.pdf) version here.

I have a 1990 dodge w150 4x4. put new alt & battery in it. still not charging wright. pull positive cable and motor dies. already went through 4 alt. could it be the black box that connects at the alt.

you need to check your electrical system with a digital volt meter-when the vehicle sits overnight, the battery should read about 12.5 volts before startup. You should get the same (or very close) reading at the large post on the rear of the alternator, then start it up. Readings should go to close to 15 volts, and gradually drop down to close to 14 volts at idle, again at the battery and the rear of the alternator. If it is much less than 14 (like 13) or more than 15 (like 16) you have a problem either with the voltage regulator or the ecm.

Battery not charging

run an ohm test on the stator wires, make sure you get readings through all combinations of any 2 wires. if you don't get an ohms reading between 2 wires that means you have a broken stator winding and the stator needs to be replaced. hook up a volt meter to your battery and test battery voltage at rest (bike off), at idle (bike on and idling should be at least 12.5 - 13 volts), and steady around 3 - 4000 rpms (should be around 13-14.5 volts. if it exceeds 15 volts your regulator is bad and needs to be replaced. if all numbers are about what I said, have your battery tested. If your battery is over 1.5 years old it should be replaced anyway.

The turnsignal usually don't work. Wehn they do work it is usually when you are giving it throttle they will not work at all with eng. not running even with hot battery.

check the battery voltage , should be over 12v with the engine stopped and 13-14v with the engine running, or it may just need a new flasher can, make sure the bulbs are all coming on including the dash and they are the correct wattage for the bike

I attach my inverter with custom battery cables and it powers up. As soon as I plug in an extension cord (any cord)it starts beeping. I don't even have anything plugged into the other end.

please check the voltage of the battery may be the voltage of battery is low or use the multi meter and check DC volts before conneceting the battery and after conneceting once more check the DC volts it could slove the problem
the beeping sound is due to battery low voltage
what is the DC input of the Inverter check the battery hook up if the inverter is of example DC 24 volts please check what is the input
