 |
|
I purchased the board from Bob's site and the components from Digikey.
I then tried to assemble the module as per the instructions here...
http://www.aeroelectric.com/articles/lvwarn/LVWarn-ABMM.pdf
It looks like a simple board, so I thought that I could do it even with
my skills??? Well, DUH!!
When I turn on the master, the 3 amp fuse immediately blows! I have
absolutely no idea how to go about trying to troubleshoot this board.
Can some of you guys give me some leadership here? Please don't talk
about testers more than a cheap volt/ohm meter and be pretty specific
about how to use even that..:>)
Thanks for your help.

Thanks, Bob! My buddy at the airport has offered to look at the board.
He has it now. If he comes up empty handed...(not likely :>))
I will take you up on the offer.

Drop it to me in the mail and I'll trouble shoot
it, fix it and tell you what I found and how I
found it.
I've built a couple hundred of these critters
and can probably find it pretty quick.
On the other hand, if it's blowing fuses, it sounds
like a hard short. Check for solder splashes on the
connector pins. I can't think of any component placement
error that would draw that much current.
