Tach Retro install and grounds

[PbFut]

Just a cautionary post for those doing cluster work. Last summer I installed a retro tach. It was the basic kit using most all of the original cluster, replacing only the printed circuit sheet, plexi window, and adding the tach gauge mechanism. Relatively easy to do if you take your time and don’t force anything. Now to the point of my post. It’s been about 6 months and all has been fine. This past week I get this funky action with the hi beam and turn signal indicator lamps, and the cluster lamps are dead on the left and very dim on the right. My first inkling as to the cause was correct. The grounds on the left side of the circuit sheet have lost their connection. Reaching up to that area and moving the sheet some corrects the problem. To be sure this problem does not return, I’ll have to remove the cluster and do some better cleaning of the grounding contact points of the circuit sheet. Not the end of the world but I should have paid better attention to the issue when assembling the kit. Just passing this on for those who may be thinking of attacking the tachometer weekend project.
