Circuit board first run Athearn SD70M.

I have got the ditch lights on one of my SD70M Athearn locomotives and the problem is i cant get the four wires to go into the circuit board holes,Can i drill out the holes without hurting the circuit board.Thanks.

They did make those holes a bit small, but it’s possible to get all the wires in without drilling them out. If you twist the ends of the wires all together tightly, they can be slipped in the hole as one large wire. They do fit, but just barely.

You can drill them carefully. I have used an Xacto blade and beveled the hole so that putting the wires through is a lot easier.

UMMMMM, I wouldn’t suggest doing that. Twist the wires tightly and they will go in. You probably got them all bent out of shape trying to get them in.
