Cluster problems

Hello Nick-Yes ,you should have 12 volts coming into the center pin that leads to your V/L. Your suppressor will probably tie into this line although I can`t see it in your picture. The other side of your V/L should show an average (the voltage will be intermittent) of 5 volts leading to one side of each of your gauges. Viewing your photo the incoming pins with the glue on them should be L to R- (1)12 volts in to the outside pair of inst. panel lights (2) 12 v. in to center inst.pnl light (3) 12v. in to V/Limiter (4)and(5) 5v. to sending unit for temp/ fuel/ oil? You can ground your sending unit wire leads briefly and have someone watch the gauge to see if they rise. If they do they`re probably okay.Good luck, electrical problems can often be a major pain.
