SOURCE: 883 wont start

The battery might just be done or warn out, if you get lights when you turn the key on, and can honk the horn and everything, then it should click, if you are able to honk the horn and lights etc. and they aren't real weak, when you hit the starter it should tick, if your lights are bright and horn is loud and brake light responds quickly, then I'd ask a Harley dealer about it.

SOURCE: have a 07 700 grizzly the battery keeps going dead

something is on ... somewhere.

That OR you arent charging.

Disconnect the battery put a amp meter between the + and the + wire. What is the reading? Anything above zero is a drain on your battery. Turn on the ignition ... what happened ... more drain?

Check your diodes in the rectifier to assure you arent loosing power to ground there because one is shorted.

Need more help, let me know ...

SOURCE: I have a 2000 fatboy stopped to get gas battery

To check if you got a charging fault, get a multimeter and switch to voltage put across the battery. You should be getting at least 13.4 volts.
Turn lights on and this should fluctuate upwards. If your getting anything lower then what I stated you have a charging problem. Rectifiers and regulators can only really be tested of the bike with a specific tester. Hope this helps, let me know how you get on.

2012 yamaha grizzly 700 new battery in just clicking noise showing error1

Just a couple wild guesses from 40+ years of experience...
1. the solenoid is bad.
2. the connections are not clean.

Make sure the ground wire from the battery is clean and tight to the frame.
Try jumping the two major solenoid connections with a HEAVY wire or (what most people use ( a screwdriver) and see if it starts...
If the engine turns over when you jump the connections, it means the solenoid is bad. If it does not you probably have bad connections at the battery + or - side.

2009 grizzly 700 will only run when starter button is held display only works when trying to start it

The primary circuit has a ground connection so everything works... your secondary circuit doesn't have a solid ground. Go over all your ground connections carefully.

Backfires when you try to rev up engine,

check fuel flow and check spark at spark plugs

According to an "ATV Rider" 2009 article, "When the Grizzly was introduced in 1998 as a 600cc machine, the top was blown right off the displacement wars of the time."
It was replaced in 2002 with Yamaha Grizzly 660, an even bigger engine derived from the well-established all-terrain vehicle (ATV) Yamaha Raptor 660R.
Grizzly's 660 cubic centimeter (cc), four-stroke, liquid-cooled single overhead camshaft, five-valve engine performs well in open country, but sometimes it causes serious problems for owners.
Before you call a Grizzly dealer, however, trying a few tricks in your garage can save you a lot of time and money.

Check the fuel level.
Locate the fuel meter indicator on top of the multifunction display.
If it does not work properly, open the fuel tank, and push the Yamaha 660 Grizzly side to side.
Ensure the fuel is not contaminated by water or rust.
If you have not driven your Grizzly 660 for a long time, drain the tank completely, and fill it with a fuel tank cleaner.

Check fuel hoses for cracks or leakage.
The hoses should be soft and simple to bend.
Replace those that show any sign of wear.

Check the compression.
Screw a compression tester into the spark plug hole, and press the electric starter button.
If no compression exists, contact a Yamaha dealer.
Wipe wet or dirty electrodes with a dry cloth.
The spark plug gap should be checked regularly

Correct the spark plug gap.
Measure the gap with a wire thickness gauge.
If necessary, adjust it to 0.8mm using a screwdriver or replace the spark plug.
Use only a Yamaha-specified spark plug.

Check the Yamaha 660 Grizzly's battery.
Operate its electric starter.
If the Grizzly starts quickly, then its battery is in good condition.
If the engine turns slowly, check the battery lead connections, and you may need to change the battery.
If the engine still does not eventually start, your Grizzly is beyond home repair.
