What’s the deal with these Fans?

[KevinC]

Hi Arrma nation.
I have a handful of these fans from powerhobby that I cannot get to work with my Spektrum SR515.
Any ideas?

The fans have reverse polarity protection, if they are plugged in backwards they will not work. Make sure they are polarized properly, the plugs have a + & - on them.

What he said. If it's not working most likely switching the wires will get it going.

I have no idea why those fans don't work. On the topic of fans not working... where is @arrma only fans? he sure doesn't seem to be working.

Those are great fans. I'd guess you have them plugged in backwards. They do come with an oddly thick port if I remember correctly. I had to sand one side down for the fan plug to fit alongside my throttle and servo plugs.

As far as I can tell, there’s only one way to plug these in. There’s a detent on the plug coming from the fan that prevents plugging it in the wrong way……..so I’m at a loss here.

Yep that’s what I’m talking about. Sand it down and plug it in the other way.

Ok, I’m using the extension as seen in the first picture. Are you saying to sand down the detent on the plug that’s connected to the fan and send it directly to the RX.…..thereby bypassing the extension altogether?
Sorry for the confusion

Yeah bypass the extension to see if that is the culprit.

No, pop out the extension wires (I have done it before and it is easy) and switch them.

I have this fan and the plug isn’t backward, it’s just unusually thick for some reason. I had to sand it down for it fit at all. Switching the wires wouldn’t have helped.

I’ll give it a shot, will report back…..

Fixed guys! Sanded down the plug, works great…..thx for your help!
