i have a 87 r10 pickup. the oil gauge and the amp meter seem to be off. the oil gauge stays at 60 or higher. it will not move lower or higher. the amp meter will tick back and forth when blinkers are on. it also changes dramatically when started, and when the dash lights are turned on. just need some help on what i should do. i have no idea what i am doing. thanks a lot!

Re: gauges on 87
when the key is turned on the oil pressure shoots to 60. when turned off it goes to 0. im not too sure on that, but i think it does that. also, the amp meter has one pin missing from it behind it. what is that piece called?

Re: gauges on 87
Try wiggling the connector on the back of the cluster. They're touchy. I think the amp meter is supposed to be that way, looks like it should have an extra pin, but does not.

Re: gauges on 87
An 87 with an amp meter gauge? Did you install a 73-75 gauge cluster in your 87?

Re: gauges on 87
Hard to explain this all without pictures.. Im not sure what the "amp meter" is. It shows the volts of the battery. I dont know what it says volts or amps. They look like this trucks model gauges . The gauges slide into clips. They are metal looking clips. Usually for each gauge theres about 3-4 metal clips that the back gauge screws go into. I have not installed any different gauges.

Re: gauges on 87
this is an amp gauge,it reads + or - current flow to/from the battery
ok you have an volt gauge(reads all plus) you may have to remove the cluster and make sure the connections are good

Re: gauges on 87
Is that the only thing that could be wrong. What are the clips called that the gauges slide into?

can you meter the actual power at the battery/alt points don't know the clip name,if it needs a clip it will have a board contact point,not just a hole i believe the oil goes high if the sender is off(power works no pressure signal) and seeing the volt gauge bounce when a signal is on,check charging other then that,check the paths on the cluster,shorts do weird things remove cluster? about 12 screws for the outer bezel then screws (in white plastic)around the outside of cluster speedo cable and wire harness plug,shifter needle,gotta be out/disconnected... it should be loose to jiggle up and out
