help with homemade passthrough please

[mrb]

I tried to build my own 5v passthrough last night,, partially successful.

I ordered some parts through mad vapers.com. 801 connector, to use with my 4072 atomizers.... some LED's, and a switch.

I'm building it in an old cigarette adapter case.... works out pretty good.

my problem: when i connect the Led light it burned out immediately.... I had it pigtail connected to positive, after the switch.. and neg to neg , after the atomizer.

I think this connection was wrong. but I saw a guy on you tube,, the detonator,, connect it that way though....
so I changed it to "inline" on the positive, after switch. it stayed on for about 4 seconds, then blew!

I took out the led all together, and it works fine.

using a usb, into a wall wart 5volt 2000mAh. am I too high on the milliamps?

also, my package of led's and switches came with little transitors in the package too,, as well as little threads(probably for atomizer wick or element?).

the transistors are tiny little peanut shaped, tan with colors left to right,, 1. purple or blue 2. yellow ...space, then gold.. I searched but could not figure out it's rating.
am i supposed to use these? when i checked them with my meter while i bridged it,, there was no difference in volts...

I actually think my meter needs a new battery because when i try to check ohms all it says is OL, and milliamps does not show anything... it's been about six years since i changed it. also, it shows around 8.2 volts when i touch the pos and neg.
strange since i am using a 5 volt power supply.
another thing..... is the atomizer supposed to glow all the time? it does not glow when i drip juice in... I kinda get a hit, but hardly any smoke on exhale.. then sometimes when i push the button and look inside it will glow feircly,,, kinda cool.
just wonder if something is wrong

any help would be appreciated

Those are resistors and you probably need to put one in the positive lead of the LED to reduce the voltage.So it would be negative to negative positve to resistor to switch.I did the same thing and gave up on LED's.

OL means overload. Your resistance is higher than your settings/scale. Change to the next higher scale until OL does not show and you get a measurement.

the battery was really weak,,, it was showing default OL for ohms and was not accurate for volts or anything...

I got a new battery and it works good now.

pulling 5.14 volts thanks my puter batt is dying now......
