oil pressure gauge goess off the scale?! help!

[Sleeper_Avant]

will search the WK terminal as its all retrofitted,

Cheers Alex

[Sleeper_Avant]

sender is big fat 2 terminal jobbie yes?

WK is single pin jobbie yes?

Cheers

[Error404]

Nope, the WK terminal is one of the two on the cotton reel looking one

[Sleeper_Avant]

ah, im screwed then as its got speaker wire or summat in there now lol

will have a looksee tomorow and try to rape the breaker

will report back by 2100hours, sir yes sir!

Right ive sorted why it doesnt work right,

it isnt connected and the wiring was all chaffed and kept going off when i wiggled the wires with the console out, shockingly dangerous how it was left if im honest

went to a breakers and cut out the full harness for the gauges

i will do a "how to" retrofit guide if you lads would think it would be of interest

I have the same problem the oil pressure gauge read to max when i turn the ignition key to the on position. What the salution?

If you had read the complete thread, post 2 on page 1 said:

"If I remember correctly, when the oil pressure gauge goes off scale, it means that there is no signal to it, i.e. kind of a warning. Hence no difference when you unplugged it. Broken wire or broken sender."

Look through the complete thread.

Someone else mentioned sensor open circuit. Have you measured the sensor resistance against a known good one ?. Should not be zero, but perhaps a few 10's or hundreds of ohms.

Unlikely to be the wiring ime, though the spade terminals could be corroded and wire open circuit inside the crimp. Recrimp wire ends if in any doubt, as the engine end also takes a fair bit of vibration.

To verify wiring and with ignition switch off, measure continuity and resistance of the sensor wire to the gauge, at the engine end against ground. Should be a few hundred ohms max. Alternatively and with ignition on, measure the voltage at the sensor wire with the wire off. Should show 12 volts or close...
