"Hi, I have a Volvo MD2020 on
"Hi, I have a Volvo MD2020 on a J105 that we have recently had to replace the alternator on. The problem I have is I didn't record where all the connections were located. I have connected the alternator as per wiring diagram from Volvo but I have a red & blue wire which is not indicated on the diagram. Everything works ok but the tacho now doesn't work. Any thoughts???? Cheers Sammy"
