Title: 3500/10 Motherboard, which pin is positive and negative?
Post by: AekaGSR on April 03, 2016, 12:46:17 PM

I was having issues witch charging, it turns out that the terminals were not seated well in their connector to the motherboard.   I decided to pull the connector out to investigate when the terminals themselves pulled out from the connector.   Unfortunately the motherboard is not labeled as to which pin is positive or negative.    Which pin on the board is positive and which is negative?

This is a LB3500/3510 motherboard.

I don't know why I didn't try my multimeter, so I did and found the correct polarity.  She's running great now!

Good news!  It's very annoying that it is not labeled.  Glad you figured it out!
