Help

I have 02 short bus

I'm converting into a grooming vehicle everything is set up. long story short I put all brand new lights on back of the bus and now the backup beeping sound is not working or the two lights that come on with it arent lighting up. the other thing is I can't figure out what is draining the brand new battery brand, it's dead within 2 hours if I go to restart it

I looked for a master switch, cant find it

That is a very severe short-circuit if it flattens your battery so quickly. I have a hard time reconciling that a light would draw so hard, but, if that's all of the work you did to it since it last held a charge, then the problem most likely will be there.
Given your description, the back-up light circuit is the culprit. Go back and confirm all the connections you made, starting with those 2 white lights & The B/U beeper. It is probably a bad connection, killing those functions.
Check the fuse block, too. You may have accidentally shorted it, especially if you cut any wires, and blew out the fuse.
Just an afterthought: did you upgrade the lights to LED..?
If its a new battery, it wouldn't hurt to check that the electrolyte level is up to where it belongs. You can't trust nobody.
BTW: Fill in your bus' specs in your profile; make, year, engine, tranny, et al. We can't help if we don't know what you have.
Good luck, and welcome to the booby hatch!

I rarely come here on the computer. If you're using an Android cell:
Tap your user icon, then, in the upper right corner are 3 vertically stacked squares.
Tap them, then select "Edit Profile."
Fill in as many fields as you can, and save.
I do know that IOS users have experienced difficulties...
On the computer it may be similar to the above process. Then again, y'all might have to explore a little! 🤞

Parasitic Draw test. Youíll need a multimeter. A cheapie one will do.

Be sure to take pictures of the fuse blocks before you begin ( donít ask me why)

Needle nose pliers are helpful
