Howdy my gauge reads 100psi as soon as i turn ignition on wired it up like the destructions said and followed a guide off here just seems odd so was hoping someone might have an idea ? Its an auto gauge electric one by the way cheers jon

 

Mine reads 5-6 bar when ticking over cold, 5-6 bar when running hard, hot, and 2-3 bar ticking over hot.

1 bar = roughly 14psi, so.........

Your 100psi equates to 7+ bar...........is this cold, tickover, what?

 

If its reading that without the engine on then the sensor wire isn't connected. The gauge reads high if the sensor is disconnected. Is 100psi as high as it goes?

 

hiya 100 is top of the scale gonna recheck all the wires and connections then and see what that shows up its when i turn the ignition on without starting

 

Think i got it sorted the sender was shorting out on the altenator thanks for your help

 

think thats right u no mate because on cold mine reads that. with the oil thick its harder to pump therefore more pressure to pump until warm an thin. why they say first 10 seconds is most engine wear because the oil is hard to pump up to the topend
