Noticed a few days ago that 2 of my aftermarket gauges, oil pressure and water temp were moving a bit erratically and tonight the speedo stopped working for a couple of minutes. Does anyone know whats wrong? Thanks Steve.

 

Where are the gauges getting their power source from? Maybe there's a dodgy earth connection nearby? Trace them back to see if someone has connected them to a power source behind the clocks and have used those horrible scotch lock connectors. They have a high rate of failing. If so, get rid of them and solder all joints!

 

Thanks for that.I,ll check this weekend, although every thing has been ok since. Steve.
