Help on Ausmicro spider board

Hi,

In my quest for building a nifty monster, recently I have gotten two spider from Ausmicro to upgrade my monster(and possibly my Awd if the mzm works out).

Without knowing how to spiderfy my AD band board(wrote to Ausmicro and posted here, but so far no news), I brought back my old monster stock board and follow the instruction of the spider installaiton.



What frustried me most is the spider board instruction said the red/black jacketed wires are the power lines, but there are 2 sets of them onboard. And there is no other wiring instruction on Ausmicro site.

And finally, from the nelly website, I found the 2-way wiring config and tried installing spider based on it. But upon installation, virtually a poof of white smoke come out as soon as I turn on the power...and after that, even I turned off the power swith on my battery box, the motor keep going until I disconnect.

Now, I have checked the connection with a multimeter and make sure there is no short between pads and wires beforehand, all wires are connected correctly and I am more than 100% sure there is no misconnecting power lines either(since I use an external source and check those wires with multimeter to double check polarity).


What I'd like to know are:

1) Is my spider board dead? What went wrong?

2) Does anyone know exactly which two wires are the power lines/motor lines on spider? Ausmicro provides no instruction....

3) Anyone has any idea at all how this spider board could work with an AD band board? I use multimeter to figure out the top two fet seems to be stacking each other in pair, and the bottom two are stacked in pair.


Thank you in advance!

I'm not sure how you would install the spider on an AD board as I haven't worked w/ an AD board.

But the bad news is that you may have fried your Spider by connecting the control leads to an AM board the same way as a Nelly... This is because the colour coded wires and the way it should be installed on the board is DIFFERENT from the Nelly.... if you don't have the instructions for the spider's install, I have a copy I can send to you through email. You can email me at locwan@gmail.com

As for the black and red power wires, the set that is on the same side as the control leads is for drawing power to the spider, and the other set which is on it's own opposite the control leads are meant to be soldered onto the motor. Hope that helps.

Locwan,

Thank you for the quick reply, and from your description, I should have it on there correctly--the two wires same side as the control wires are power lines, and the opposite two big wires are to the motors(following the nelly for the big wires only), and I have installed the color coded control lines are exactly installed based on spider instruction...

Yikes, that is sad news. What I'd like to know is what happened...I just couldn't think of any possilbe reason why this happened?

Would it be possible at all the fet inside are shorted out?--I remembered reading from other thread that someone had similar exprience when installing fet onboard of a miniz.

ic what you mean now. I agree that there could be a possibility that the spider was defective to begin with.. perhaps you can contact ausmicro and explain the situation to them and see what happens. I hope things will work out for you.

Still no news after two emails...does anyone has any idea how to reach them besides email them via their site?(like an actual email address?)

Or better yet, any idea what else could have gone wrong? I still have a second board, and I'd like it to be working this time.

Aurora, look for any shorts between adjacent pads on the mini-z PCB, this can cause iossues and is the #1 cause of all nelly and spider faults, lol...

Aaron's spider turbos are made on production quality PCB's, so the error rate would be quite low, although it can happen.

Just shoot him an email aaron@ausmicro.com and he should ge back to you or just post up at ausmicro.

Aaron is a standup guy, most likely he hasn't asnwered since it's Easter holidays at the moment. Us Aussies really like our holidays!!!!

cheers,

ph2t.

ph2t,

Thank you for the rescue.

I too do look forward to putting a nelly/spider onto my cars. For the check, I did use a multimeter to check it before and after the mod, and checked it pad by pad before turning on the power. Thanks for the contact--I will try getting in touch with aaron at ausmicro, and hopefully make proper arrangment with him.
