What the heck
Second BatteRy has heated up and blows
out the top... What's Goin on.?
All wires are tight and insulated I guess it's over charging, why?

Seems like it is overcharging. What voltage is you're regulator pushing to the battery? What brand of battery are you using?

Yea...overcharging would be the cause. Haven't heard of this happening any other way.

The battery is new I'll swap it out... The regulator is what, 75$? Do ya think HD would carry that part for BDM?

Like WoodB said, do your diagnosing, not throw parts at it. Say we have a new battery ready to go. It's not going to blow up you test the charging system. First it has to really boil the liquid inside so that takes tea kettle time either way.

So, with ohm/volt meter in hand, dial the meter to 20v. Start the bike and let it idle. Place the meter prongs + and - clipped/held onto their correct battery posts. Read the volt meter. Anything past 14.7v is going to start the kettle cooking we see 15/16v we rev the engine some... Bingo! Found the problem anything well over 15 volts.

Does it happen while you are riding or when you try and start it?

I had a positive wire frayed that was touching the body, caused my battery to overheat and melt the terminal but only when I tried and start it.

Also, it may take a while to find faulty VR. Mine tested fine, took about 10 mins running the engine to start overcharging... So if it looks good iddling in garage try to ride a bit with multimeter connected and keep an eye to voltage changes...

voltage regulator

Don't buy any regulator but a cycle electric one. Not cheap but reliable and not a shunt type. Do a search on the sight for the one to buy!!! I went trough 2 of the shunt type ones.

Great advice, thx.
After riding for a good 30 minutes the battery starts to smell. Can only smell it at a light though, that one hour non-stop blew the top right off the battery, lol.
The bike completely went dead immediately with no warning, I coasted into my driveway, thank the battery gods I was close to home :whoop:

So you did not have multimeter connected while riding though boiling battery and not melted posts pretty much shout too high voltage to me. I would check the whole charging system, check "how to" there are instructions.

Well if anything, pretty interesting it takes 30 minutes or less to cook the kettle keyput.

I'd ride it in the winter. Have a flood light aimed before the back tire so it melts the snow/ice some. Run a few 100w aimed at your hands for glove warmers. Run a gaggle of xmas lights around the bike and yourself so this keeps you toasty warm and I think the battery will last a lot longer the next time out... no meter checking needed.

:cheers: :up:

Ok, have the new battery!! It's hooked up and NOTHIN! No head light no tack... I'm looking for a fuze that blown but so far no good
IF the regulator is bad will it knock out the rest of the bike/ignition??

I guess it's over charging, why?
There are 3 events occurring:
1. AC = Begins.
2. VR = Converts.
3. DC = Ends.

AC in its natural form = +-+-+-+-+-+-+-+-+-
DC coverts to =
---------- ~ Battery Post
++++++++ ~ Battery Post

AC Travels = < This way and that way ><><><><><>
DC Travels = > This way only >>>>>>>

AC out the alternator is traveling <><><><><>
VR captures > is a given. VR captures < as well and the one is more or less spun around or converted to travel >>>> as the other direction was >>> this way to begin with.
DC is the separation of a chemical reaction between plates is + sits at this end and - sits at that end.

Of course there is a 'for every action...,' that movement is still AC as in a balance of pings back and forth. And it can be measured.

However, I am getting to the 'Why?' part that the OP was wondering. The electrical system is just 3 fundamental moves to think about is who is the problem in all this?

Why it's AC. No... It is putting out full kettle boil me out and pop goes the we sell new batteries is go get one.

Why it's the VR. Yes... It is not converting the other wire for DC direction, nor can it control the voltage. It says; look at the 2 wires out of the stator is for example saying, 16 amps is one wire, 16 equals the other, 32 amps of voltage is my battery would last longer if 16 was cooking that puppy so I'm going to remove or plug up that one prong out the stator and run 16 amps. My new battery blows @ 30min X's 32 amps.

Why, if my math is right, I can run 16 amps X's 60min before the battery blows.


:cheers: :whoop:


Signed,

Never ask me why... Why not? This one is for franco. The OP better close this question and give up the who in the loop is it?

Basically, yes.

Remember, even though that was headed in the battery of 32 amps? It still had to pass thru the VR and this drops current. It still is being separated in the battery, but say the battery is now the resistor/converter in a way. This is 16v out the battery and the rest is kettle'ing some liquid in a boiled state.

The lights are still in a math kind of rated for, 'uses so much voltage' or it burns out. So no, a 12v bulb cannot last against 16v+ of input or more at it. We are handcuffed to Ohm's laws or the house burns down, the battery blows, you get knocked on your feet you plug something in, etc.

How could you sort of answer your own question I quoted and not buy the volt-reg with the new battery? Right now, your bike is a rolling battery charger, not a balanced kind or start riding as designed. You have a failed part that is causing you to keep buying batteries:

1. Not the Battery = Works for 30 minutes and that means it still worked in that time-frame.

2.. Not the Stator/Rotor = That is working beautifully as it blows bulbs and battery tops.

3. It's the VR = This says it cannot regulate; is it a bridge alright... bridges both lanes to boil the batt and is not regulating the voltage ~ BINGO is the WHY!

:hi: :D
