Recently i swap to my 88 pickup a new sr5 cluster, today i change the original light to new one for gauge, all time the cable was disconected of light sensor ok. Issue its today i change work fine but in middle to my work travel the gauge down, not reading what happen here?

 

Let me try to make sense of this....

You swapped your cluster out with a new one that had an oil pressure gauge instead of just a light, yeah?

It was working fine, then just up and quit, yeah?

Did the gauge slowly go to zero or was it like it instantly lost power and went to zero?

Check all fuses and connections.

 

You need to change the oil pressure switch too. There's one for an oil light and a different one for a gauge.

 

I'm told (on this site) that using the old oil pressure switch (for the oil pressure light) with the gauge will damage the gauge. You have to change the switch for a sensor before you apply power.

 

Yep, i swaped and change the light sensor,for new gauge sensor, gauge work great, but in any moment loose pressure, to cero

 

Check your oil. Check actual oil pressure with a manual oil pressure gauge.

 

I need clarify something, ok when connected the gauge wire to new gauge sensor and switch the key, the oil gauge up to 3/4, not supose gauge take pressure or up when engine its on?

 

When you turn the key to "on," the oil pressure gauge should read zero (because there is no oil pressure when the engine is not running). When you start the engine, the gauge should rise smoothly to somewhere near 1/2 way.

 

Yep, when turn on swithc the gauge up.

זה נשמע כמו בעיה בחיווט. סמן את כל המחברים.

 

So the gauge goes up, then as the engine gets hot the gauge goes down?

 

The hell???

 

I told him to check all wires and connectors. From his grammer and name it seems like he is translating from Hebrew.

 

Lol wow ok.

 

Im sorry my english it very bad, i try.
No only make this when wad connected the firt time, after 10 min go down with engine on, aftet this no up no down i think gauge was fry

 

If it worked fine and then suddenly quit I would recheck all the work you did. Double check to make sure there are no loose/damaged connections, connections that came off, or any damaged wires. Was the sensor you put on new or used? If used I would consider it suspect. I would also verify it is the correct one. There is probably a way to cause the gauge to peg out both ways to verify its operation. Some of the other guys may know how.

 

I check the sensor cable with tester and open circuit the light turn on, but gauge not move from cero

 

Hey Budger
Good news almost the gauge its not fry, today up and down after some minutes

 

I change sensor, for new one original, gauge not up from cero, i ask? Need any groun cable connection? Only have one roun conecction
