    O.k., I pulled the CMS from the dash. Luckily it wasn't too tough. I found that the TD62504P chip looks like a mini volcano, i.e. cracks like it released the magic smoke from inside and also a bit of a scorch mark on the board near the pins. Could this be the reason for my non-functioning CMS?? Also, when I was disassembling things to get to it I found a connector that has 2 red wires and 1 black. It wasn't connected to anything and I can't find where it is supposed to go!! Any ideas??? Steve

    So to remove them, I pull the boot back and then have to unscrew the wire from the plug correct?

    Is there a trick to pulling the wires from the spark plugs?? Do the just pull off or are they screwed in somehow?

    Headlights and tail lights as well as dash, signals and even the light for the CMS all work correctly. Simply no activity on the CMS and intermittent Tach.

    CMS = Computer Monitor System, I believe. The LCD screen for the warning lights on the dash. I'll try cleaning and reseating. Should I resolder the board while I'm at it or can the cleaning be done without removing the CMS?

    Hi all! Just bought myself an 85 Venture xvz12! I'm now in the process of fixing some of the issues it has. The biggest one is the CMS doesn't seem to work! The rest of the gauges seem to be ok except the RPM gauge is intermittent. Nothing at all shows on the lcd. I've tried replacing the 15A fuse but same issue. I have read about the CMS needing to be resoldered but all the posts I've read have some function! Mine has none!! Suggestions?
