slow fluctuating speedometer

[ghettogeddy]

So I installed a 160amp High Output alternator yesterday and today I noticed while sitting at work idling in the parking lot the needle was slowing jumping up and down and I was not moving. i know these are vss so they run off of voltage but can having a higher output alternator cause this and how do i fix it?

I'm gonna have to look at it all. But we only Undid the power steering line And the fuel fail so I don't know what else could have gotten knocked loose.
