Battery is over charging. It has burned up two batteries. It is also blowing out other electrical components. The speedometer is dead. The headlight is out no turn signals and maybe the fuel pump. The bike died and there was battery acid all over. It did this twice.
Additional information such as miles and changes from stock helps too...big difference between 5,000 miles and 100,000 miles
Some history of ownership helps to establish condition of motorcycle.
Something like garaged kept, well maintained, custom built, a rebuild or a bike found in a junk yard helps to get a picture of condition.
Explaining what overcharging means to you helps? 16 DC volts, 18 DC volts at battery post with engine ON?
Explaining what "burned up two batteries" means to you helps. Does this mean it melted, caught on fire?
Explaining what "other electrical components" means to you helps...lights, a radio..what?
Explaining what "speedometer is dead" means helps...lights in speedometer?, odometer?, speed read-out?
From a distance and with the minimal information available it reads like it started as an initial charging system problem.
But without knowing what diagnostics have been performed or what items have been changed it really makes things difficult.
One possible component would be a voltage regulator.
Shorted or melted wires are possible due to damaged regulator.
A shorted stator in combination with regulator.
A complete electrical system check with a simple digital voltage meter might help.
If someone has been jump starting bike from a running vehicle then entire electrical system requires review.

Generally when requesting assistance it helps to provide year and exact model.

It's a 2002 dyna wide glide.
It has 29,000 miles on it.
I just purchased the bike about a month ago.
I noticed the speedometer was acting weird. It would not show speed then showed my speed. The check engine light came on and the odometer read error. I asked the guy I bought it from and he made it seem like no big deal. Then after going on a 4 hour ride. The speedometer quite working all together. The lights on it still work but no speed read out or odometer reading. Then the bike lost power like it had no electrical. I had it trailered home. Upon further review I found that the battery looked cracked. So I assumed that the battery was bad. I replaced it but had no turn signals or speedometer or low beam. Again the lights on the speedometer work but thats it. I thought no big deal I can use hand signals and not haul ***. I went out day before yesterday for about another 3 to 4 hour ride. Then all of a sudden it was like the bike wasn't getting enough fuel. Anything over 1/4 throttle the bike would bog out back fire and loose power. Then it died all the way and had no electrical with battery acid leakage all over the battery container. The battery was cooked. So I figure that the battery is being over charged. That the first battery wasn't just cracked but that it had overcharged as well. Now wanting to see what is going on I got a new battery again. Put it in and have no fire. I'm not sure yet if I'm not getting gas or not getting spark. The bike has been garaged its whole life and is very clean and well kept.

Once you boil the battery dry the alternator can go hay-wire, so, if the regulator is bad it'll boil the battery dry then the voltage can climb way above normal. In cars it can easily exceed 100 volts, enough to fry just about everything on the bike.
Hook up a good battery and start the bike (if you can) and measure the voltage as you slowly increase the RPM. If it exceeds 16 volts stop and figure out why. Once you get the voltage stabilized you can troubleshoot the rest of the problems.

Battery found to be cracked.

It reads like charging system problem.
Possible voltage regulator issue.
Stator also requires review.
A simple digital voltage meter to measure bot d/c and a/c voltage should help diagnostics.
Even the free(with coupon) digital meter from Harbor Freight would help.

Using a real computer go take a look at the sticky at top of electrical section of forum.
It has a breakdown on how to check. There is a part 1 and part 2 that can be helpful.
Make sure to neutralize the acid splash on frame or you will develop significant rust.

I apologize to everyone for my lack of knowledge in how to explain the situation

You can also check computer codes via speedometer on your year and model.
I do not have the steps but a simple google search will bring up the process.

The 2002 Dynas have a simple single phase alternator and an anemic one at that. Give your battery tray and all areas near it a baking soda bath (mix water with baking soda) to neutralize the acids on your bike. I have a 2002 Superglide and it can be a reliable motorcycle, but you have to learn it. Get A new battery, find a battery shop or indy that sells batteries and get DEKA ETX20L or equivalent, Using a smart tender charge the new battery completely. Do a diagnostic test of the alternator, there is a charging sys.test in the DIY section of this forum. I strongly recommend a Cycle Electric Regulator as a replacement. If you need a new alternator again Cycle Electric. Most Harley Davidson dealers won't work on your bike due to the age of the bike. I see a brass ring in the battery tray, if the replacement battery has those, use them, the cables need to sit flush with the battery case and post.
