110cc taotao atv rectifier issue help

[rx41761]

Please help my son's atv died won't start. Found 3 of 4 wires pulled out of rectifier. Not sure where they go back into harness cliff. The diagrams I found show yellow white green and red wires and there location but my harness has black instead of green. Ok to put the black wire in that location? And is this my no start issue? Thanks!
