lots.... and LOTS of questions about my Gorgon

[JustnWynn]

It just came off of a brand-new-got-it-today battery charger
As sure as I can be i suppose.

 

[JustnWynn]

Ok.. how do I check and see if I've shorted my battery?? I have the multimeter

 

[CertifiedMike]

Lets back it up a sec. We are testing for voltage.
Before we go there... the fan, what fan did you buy? Got a link?

 

[JustnWynn]

Its new. Rocket fan from horizon hobby. For the gorgon

Sep 15, 2024

Just for the sake of those that need it and don't know it...

Welcome to learn your multimeter 101

Probes: If your probes look like they are all plastic, then they have plastic caps covering the metal probes, and they have to be removed. (They just pull off)

Blue Arrow = AC Voltage
Red Arrow = DC Voltage
Purple Arrow = AC milli-Voltage for low voltage AC
Yellow Arrow = Resistance...

Read this a few times. Its got answers!!!

If you shorted out your battery, you'd have a fire. If it was quick, maybe just a few big sparks.
It would be a big event most likely.
You could have fried the fan if 11.1 was too much voltage for it.
My fans are not rated for 3s for instance. That could have been your initial issue too.

 

[CertifiedMike]

40mm Rocket fan max voltage is 8.4 (2s)
The fan may be fried.
Lets leave the fan out for now.
Do you have a programmer card?
Do you know what yhat esc came from specificlly?

 

[JustnWynn]

I do not have a programmer card. I don't even know that is. Maybe I do?? Lol
And no clue. Something arrma 3s

 

[CertifiedMike]

We dont need to get into the card either yet. The card is a way to make setting adjustments on your esc. Such as setting your operating voltages.
Some escs can be programmed without
Got any numbers or anything on the esc?
I'm going to see if I can find how to program the esc without a programmer card.
Hopefully its in an Arrma manual.

How about those power wires? We are going to need battery power when this all goes together again.
Do you have the connector soldered?

 

[CertifiedMike]

Have you verified voltage on your battery as well?

 

[WickedFog]

You need to ditch those butt connectors. They'll melt if you fire up that motor. They can't handle anywhere near the current your electronics are going to draw from that battery, then you'll have a fire, like for sure.

I can't see in the pics what's going on. Can you draw up a diagram of what you have going on there?

 

[JustnWynn]

ok, bud. i have been learning myself how to solder. lol. its stil very bad.. but I've gotten as far as putting solder on these to little guys:

right.. the battery.. confirmed at 12.58v

pretty basic i think..but that doesn't mean its right. lol
I've got the esc hooked to the motor. i had the fan going to ch4. the esc on ch2.
the power cable i HAD the butt connectors on also had a small connector for the servo like what you had suggested t'd into the dean connector side. going to the servo, which has not been hooked up yet.
is that what you're looking for, sir?

 

[WickedFog]

Yeah, that all sounds right. But I am trying to figure why you had a spark. Higher voltage setups, like 4s and up can spark when connecting the battery. But I have never seen it on my 3s stuff. Maybe that's all it was though.

More heat. And get your soldering iron tip nice and tinned first. On bigger wires, I'll often have enough on the iron that it's about to drip. That will help a lot on the bigger stuff.

What soldering iron are you using?

 

[JustnWynn]

its the little battery powered ryobi one. i got in anticipation of the orlandoo hunter stuff you and i had discussed a while back. you think it may not be big enough for this job? also i dont have a chisel tip yet.. so its just the pointy one it comes with

Oh yeah, that will be fine for like 16awg and lower. But for the bigger wires, that soldering iron won't keep up. The bigger wires will soak up that heat faster than the iron can replenish it.

I'd grab an adjustable one that you can crank up to 400°C+. And the bigger the chisel tip you can get in it the better.

@Greywolf grabbed this guy, and this would definitely help on the cheap...

Or a mini torch. I just soldered motor extensions week or so ago on a TP motor using only a mini torch & 63/37 Kester.

That's the way my dad did anything bigger than 10awg.

i like where your head is.. but its too close to everything for that... i beiieve i almost have this bad boy licked.. am i plugging this battery and seeing whats what? no servo, no fan. just the esc, right?
