In the last 12 months my wife's AN400 has been having starting issues acting like the battery is discharged if it sits for more than a few days (hot or cold weather). Initially I thought it might be the battery, but after replacing it (twice) the bad behavior continued. She did have the dealer perform the recall maintenance on the rectifier back in 2011 so am guessing that should not be the problem.

As noted above I have replaced the battery twice. I also purchased a battery charger/tester unit that shows the battery status is good and, when it finally starts by using the chargers "emergency start" option the "alternator" test shows good.

One thing I noticed by leaving the charger attached is that after starting the charger will continue to charge the battery for the first 15 minutes after which it will turn off after displaying that the battery is fully charged. Shouldn't the stator/alternator have already done this in the same span of time?

The current behavior follows the description of the cause for the recall service that was performed in 2011 so I am at a loss as to why it is encountering this issue. I called the dealer where I bought my AN650 as the one who sold my wife the AN400 is out of business and they said it had to be either:

1) the batteries going bad (3 of them?)
2) the rectifier issue that she had the maintenance done for
3) a stator (alternator) issue (but the charging unit's test shows it is good)

Has anyone else encountered this with an AN400? My AN650 can sit for the same amount of time and it starts up without a problem.

Sorry but I can't help you........ It sounds like the Burgman gremlins are at work.

What non - standard electrical stuff has been added?, that could cause constant draw or under seat lite on?

You should perform a dark current test (Suzuki calls it a battery current leakage test) to determine if some parasitic load is draining the battery. The dark current should not exceed 3 mA per the 2007 specification.

Here is the procedure:

If it does then you'll need to determine what is causing the excessive draw. Do you have any added devices that might be drawing current with the key off?

Things that receive power with the key off are the rectifier/regulator, fuel pump relay, ECU, instrument cluster and the trunk light.

Simple things first make sure the trunk light is off when the trunk is closed, it could also be that rectifier/regulator has failed and is partially shorted.

If the under seat light is not staying on or the parking lights being left on then I
would suspect the regulator/rectifier if the diodes are a bit leaky it will discharge
the battery trough the alternator, mine does not like starting even with a fully
charged battery if it as a charger connected and switched on.

No non - standard electrical stuff has been added. We did add the adjustable back rest for the driver from Suzuki, and a Givi trunk box.

Thanks - I will give that a try, and progress through the other suggested checks as well. No additional electrical components have been added to the bike so that check is an easy one.

Did the light under the seat check - it is going off when the seat closes. Also performed the dark current test and it passed, never exceeding 3 mA. Looks like a trip to the local bike shop is in order to get this figured out (hopefully).

Starting Problem

I am having this same issue on my 2008 - Burgman400. Did you ever figure out what was causing the trouble.

Thank you.

Count me in, dead in the driveway club too.

Two days ago; First wouldn't start after being on the maintainer. But, It had been run two weeks ago.

Put a 10 A charge on the battery and it started, but not as fast as normal. Decided to replace battery. Fully charged before starting.

Today; Turned on key, got F1 light, waited for it to go out, hit starter, now total black out. Nothing works including the under seat light. Battery showed 4v so I quickly disconnected (don't want to waste a new battery). Jumped from deep cycle batteries, no lights or dash indicators.

Checked all dash fuses left/right and solenoid all 0 ohms.

Will go check for parasitic drain.

Suggested things to check.
Starter switch.
Solenoid
Rectifier
Starter, I don't know how to do this yet.
Beautiful day wish I was riding.

Measured drain with ignition off 5ma
Measured drain with ignition on 10ma

I would think the ignition on drain would be much more.

Well after removing the front leg shield and checking out all the wiring, nothing was found amiss.

I jumped my deep cycle directly to the bikes + and - cables and it fired right up. Turns out my new AGM battery was DOA. Measured 11.8 VDC after sitting a bit. Wal-Mart quickly exchanged it and it fired right up.

Electricity can be a strange thing. First DOA battery I have ever had.

Hey guys, I bought a AN400 Burgman 2001 model and from the get go it had starting problems when the dealer delivered the bike to me.
Exchanged battery, still wouldn't start up, dealer took bike back, jumped the battery from a car and worked immediately.
They gave me a free battery charger and a new battery, but it would still take up to 30 to 60 seconds to start up and 3 days ago, it just wouldn't start and the battery ended up dying.
I charged it up over 24 hours and it started up really quick, did about 45 minutes riding on it (shouldn't it have continued charging while riding it?) and after just 2 days in the garage not riding it, it doesn't start anymore.
Got it charging now again in my lounge.
Any ideas what to do??
